IonQ, Inc.

Key Points
Quantum computing stocks are on fire over the trailing-12-months, with IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. soaring by up to 3,140%!
The Trump administration is rumored to want equity stakes in Wall Street's high-flying quantum computing pure-play stocks, which would open up a can of worms.
History tells us quantum computing stocks are bound to face growing pains.
Though artificial intelligence (AI) has been the hottest game-changing innovation on Wall Street since the advent and proliferation of the internet in the mid-1990s, it's not the only next-big-thing trend fueling investor excitement at the moment. The evolution of quantum computing is playing a close second fiddle to AI.
Investors need only look at the trailing-12-month returns of quantum computing pure-play stocks to gauge the level of excitement for this innovation. Shares of IonQ (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), D-Wave Quantum (NYSE: QBTS), and Quantum Computing Inc. (NASDAQ: QUBT) have respectively soared by 284%, 3,140%, 2,760%, and 1,310%.

Quantum computers have the potential to tackle complex problems that today's classical computers wouldn't be able to solve in our lifetime, or flat-out can't do. This includes running molecular simulations to help drug developers target treatments, assisting cybersecurity companies to make their platforms more secure, and speeding up the learning process of AI algorithms. It's a technology with high-ceiling potential.
It's also an innovation that may be piquing the interest of President Donald Trump's administration. Based on a report from The Wall Street Journal last week, the Trump administration is tinkering with idea of taking equity stakes in IonQ, Rigetti Computing, and D-Wave Quantum. While this might sound great on paper, it would very likely be terrible news for investors.
Government stakes in quantum computing stocks would be troublesome
Let me preface the following discussion by making clear that the WSJ report is a rumor, with a U.S. Commerce Department official telling CNBC last week that it's not in discussion with quantum computing pure-play stocks to take equity stakes. Nevertheless, IonQ, Rigetti, D-Wave, and Quantum Computing Inc. all rallied significantly following the report.
With all four of these companies actively looking to expand the reach of their quantum computing infrastructure and maintain a healthy level of research and development spending to improve the efficacy and speed of their computing solutions, investments from the federal government would certainly help. These are businesses that, by Wall Street's consensus expectations, will lose money and burn cash through 2028, if not considerably longer.
We've also witnessed the willingness of the Trump administration to take equity stakes in public businesses to ensure everything from domestic chip fabrication to access to rare-earth metals. Thus far, federal government equity stakes have been taken in chipmaker Intel, along with MP Materials, Lithium Americas, and Trilogy Metals.
But even if the Trump administration did take equity stakes in one or more of Wall Street's quantum computing darlings, it would come at a price.
Firstly, there would be an expected issuance of shares to the federal government. Common stock offerings are dilutive to existing shareholders, which would possibly put near-term pressure on the share price of IonQ, Rigetti Computing, and/or D-Wave Quantum.
Perhaps the bigger issue is that government equity stakes in public companies may put the interests of the government ahead of what's best for these companies over the long run. Although the Trump administration's stakes are designed to be passive, elected officials in Washington, D.C., ultimately establish the laws that impact these businesses.
We've witnessed instances during President Trump's second term where he's used American businesses as bargaining chips when negotiating tariff and trade deals. Government stakes wouldn't be ideal for IonQ, Rigetti Computing, D-Wave Quantum, or their investors.
But wait -- there's more
Unfortunately, rumors of the Trump administration wanting stakes in quantum computing pure-plays is just the tip of the iceberg of potential red flags and headwinds with these stocks.
Arguably the top headwind for companies like IonQ, Rigetti, D-Wave, and Quantum Computing Inc. is history. While history has paved the way for numerous next-big-thing technologies to positively alter the growth arc for corporate America, there's no mistaking that early stage bubbles have been a given for every game-changing technology since the mid-1990s.
Including the internet, we've watched numerous hyped innovations fail to live up to expectations in the early going, including nanotechnology, 3D printing, blockchain technology, and the metaverse, to name a few. Investors have a habit of overestimating how quickly a hyped technology will be used on a mainstream basis, which eventually results in lofty growth projections not being met.
Quantum computing remains a nascent technology that has plenty of potential on paper, but isn't being commercialized on a broad scale, as of yet. It's probably going to need multiple years to evolve and mature.
The other headwind that investors simply won't be able to sweep under the rug has to do with the valuation of quantum computing pure-play stocks.
The dot-com era led to the most expensive stock market in history, spanning more than 150 years, according to the Shiller price-to-earnings ratio. In the months leading up to the internet bubble bursting, market-leading stocks like Cisco Systems and Microsoft were consistently peaking at trailing-12-month (TTM) price-to-sales (P/S) ratios of 30 to 40.
As of the closing bell on Oct. 24, the respective TTM P/S ratios for Wall Street's four hottest quantum computing stocks are:
IonQ: 263
Rigetti Computing: 1,243
D-Wave Quantum: 375
Quantum Computing Inc.: 7,322
Not even a high-double-digit or triple-digit annual sales growth rate can sustain or justify P/S ratios tipping the scales between 263 and 7,322!
Though it's possible these quantum computing stocks will be long-term success stories, historical precedent points to eventual significant drawdowns for all four companies in the quarters and years to come.

The Donald Trump Administration May Want Stakes in Quantum Computing Stocks IonQ, Rigetti Computing, and D-Wave Quantum -- and That May Be Terrible News

Seagate (STX) came out with quarterly earnings of $2.61 per share, beating the Zacks Consensus Estimate of $2.36 per share. This compares to earnings of $1.58 per share a year ago. These figures are adjusted for non-recurring items.
This quarterly report represents an earnings surprise of +10.59%. A quarter ago, it was expected that this electronic storage maker would post earnings of $2.46 per share when it actually produced earnings of $2.59, delivering a surprise of +5.28%.
Over the last four quarters, the company has surpassed consensus EPS estimates four times.
Seagate, which belongs to the Zacks Computer - Integrated Systems industry, posted revenues of $2.63 billion for the quarter ended September 2025, surpassing the Zacks Consensus Estimate by 3.93%. This compares to year-ago revenues of $2.17 billion. The company has topped consensus revenue estimates four times over the last four quarters.
The sustainability of the stock's immediate price movement based on the recently-released numbers and future earnings expectations will mostly depend on management's commentary on the earnings call.
Seagate shares have added about 166.9% since the beginning of the year versus the S&P 500's gain of 16.9%.
What's Next for Seagate?
While Seagate has outperformed the market so far this year, the question that comes to investors' minds is: what's next for the stock?
There are no easy answers to this key question, but one reliable measure that can help investors address this is the company's earnings outlook. Not only does this include current consensus earnings expectations for the coming quarter(s), but also how these expectations have changed lately.
Empirical research shows a strong correlation between near-term stock movements and trends in earnings estimate revisions. Investors can track such revisions by themselves or rely on a tried-and-tested rating tool like the Zacks Rank, which has an impressive track record of harnessing the power of earnings estimate revisions.
Ahead of this earnings release, the estimate revisions trend for Seagate was favorable. While the magnitude and direction of estimate revisions could change following the company's just-released earnings report, the current status translates into a Zacks Rank #2 (Buy) for the stock. So, the shares are expected to outperform the market in the near future. You can see the complete list of today's Zacks #1 Rank (Strong Buy) stocks here.
It will be interesting to see how estimates for the coming quarters and the current fiscal year change in the days ahead. The current consensus EPS estimate is $2.53 on $2.59 billion in revenues for the coming quarter and $10.55 on $10.34 billion in revenues for the current fiscal year.
Investors should be mindful of the fact that the outlook for the industry can have a material impact on the performance of the stock as well.

Seagate (STX) Q1 Earnings and Revenues Surpass Estimates

Key Points
Pure-play quantum stocks have delivered monstrous returns over 12 months, as governments see encryption vulnerability as a security priority.
"Q-Day" (when quantum computing breaks most standard encryption methods), now estimated for 2030, is accelerating spending.
Despite steep losses, billion-dollar funding and technical breakthroughs signal that quantum computing is moving from research to commercial deployment.
Industry experts still treat quantum computing as speculative science, but the smartest capital allocators are betting billions that it's the next trillion-dollar frontier. BlackRock, Temasek, and Nvidia just backed PsiQuantum's $1 billion funding round at a $7 billion valuation. When Nvidia, which saw the potential of artificial intelligence (AI) before anyone else, starts writing checks to quantum start-ups, it's validation of the ecosystem.
The disconnect between public market skepticism and private market euphoria creates opportunity. Governments are treating quantum supremacy as existential, terrified of losing encryption advantage when "Q-Day" arrives.

That's the point when quantum computers become powerful enough to break widely used encryption standards. Enterprises are already paying for quantum services today, proving demand exists before the technology even matures.
The three pure-play quantum stocks -- IonQ (NYSE: IONQ), D-Wave Quantum (NYSE: QBTS), and Rigetti Computing (NASDAQ: RGTI) -- have delivered staggering returns over the trailing 12 months, respectively, underscoring Wall Street's sudden interest in this group.
Read on to find out more about these top quantum computing stocks.
The acquisition engine pushing quantum infrastructure
IonQ agreed to acquire Oxford Ionics for $1.075 billion and received U.K. Investment Security Unit approval in September. Oxford Ionics' Electronic Qubit Control integrates ion-trap control onto a classical chip, strengthening IonQ's trapped-ion road map.
The company also moved to build quantum networking via acquisitions of Lightsynq and Capella, and in July, it completed a $1 billion equity offering, bringing pro forma cash and investments to about $1.6 billion as of July 9.
With strong cash reserves and aggressive acquisitions building both hardware and quantum networking infrastructure, IonQ scans as a top infrastructure play in the quantum computing landscape.
The contrarian play making money
D-Wave Quantum skipped the race for universal quantum computers and doubled down on quantum annealing, a practical approach to optimization problems that enterprises can use today. Its new Advantage2 system (Zephyr topology) increases qubit connectivity from 15 to 20, improving embeddings and solution quality for supply chains, portfolio management, and research and development.
Over the last four quarters, more than 100 customers generated revenue, proving demand exists beyond pilots. With approximately $819 million in cash as of June 30, 2025, D-Wave has a runway to keep building. It isn't profitable yet, but it's the contrarian quantum play with real systems, real customers, and early commercial traction.
The pure-play on quantum supremacy
Rigetti Computing is the high-stakes quantum play with one of the boldest road maps. The company recently hit a technical milestone: Its Cepheus-1-36Q system, launched in August, achieved about 99.5% median two-qubit gate fidelity, halving the two-qubit error rate versus the prior Ankaa-3 system.
With $571.6 million in cash and investments as of June 30 -- after completing a $350 million at-the-market equity offering in the second quarter -- Rigetti has a long runway to push its superconducting, chiplet-based scaling strategy.
For investors, this is high risk, high reward: If even one road map breakthrough sticks, upside could be substantial. The company's vertical integration -- allowing it to design and fabricate quantum chips in-house at its Fab-1 facility -- gives complete control over innovation cycles.
The quantum leap worth taking
Billion-dollar funding rounds, rapid regulatory clearances, defense urgency around encryption, and (most crucially) the number of paying customers are all stacking up. These dynamics echo early AI investments circa 2015: outrageous until they weren't.
The risks remain obvious: The technology could stay perpetually "five years away" while conventional systems keep advancing. But with businesses deploying quantum computing for optimization, governments treating it as strategic, and big tech validating the ecosystem, the technology is moving from theoretical to tactical.
IonQ offers infrastructure dominance, D-Wave provides near-term revenue, and Rigetti has moonshot upside. Buying a small position in each of these names and holding them indefinitely could generate life-changing returns, given the tech's awe-inspiring potential.

3 Quantum Computing Stocks to Buy Now and Hold Forever

Key Points
IonQ's CEO believes its technology will replace GPUs.
Nvidia is slated to rapidly grow thanks to increased data center spending.
Nvidia (NASDAQ: NVDA) has been the undisputed king of AI investing, although some competition has started to emerge recently. However, these are traditional computing companies, not quantum computing businesses like IonQ (NYSE: IONQ). Quantum computing stocks have heavily sold off in the past few days, making them far more attractive than they were just a few weeks ago.
With quantum computing potentially threatening traditional computing's dominance in the artificial intelligence sector, is IonQ the better investment over the long term versus Nvidia?

IonQ made a bold prediction about its future
IonQ's CEO Niccolo de Masi stated in an interview that he believes quantum processing units will eventually replace graphics processing units (GPUs) in accelerated computing applications. He compared the rise of quantum processing units to how GPUs replaced CPUs in situations where more computing power was needed.
That's a bold proclamation, but it could have huge ramifications if it pans out. Nvidia is the world's largest company and is putting up huge growth figures because its GPUs are in such high demand for AI computing applications. If IonQ could rise to replace Nvidia, that would result in monstrous returns that would turn meager investments in IonQ into more than a million dollars.
But is this realistic?
There's no guarantee IonQ will be the winner
The AI computing market is massive. Nvidia projected that global data center capital expenditures will total $600 billion in 2025, but rise to $3 trillion to $4 trillion in annual spending by 2030. That's a monstrous market, and if Nvidia can keep its market share, it will be slated to deliver massive growth for investors.
But could IonQ take some of that massive buildout figure? Likely not. IonQ and its quantum computing peers point toward 2030 as the turning point for the commercial viability of quantum computing. This means that most quantum computing companies won't see significant sales until this time frame. That's already after the bulk of the AI infrastructure has been built out, so it's unlikely that IonQ will be able to have a massive effect on the AI arms race, although it could allow companies to push into the next frontier of AI in the years following.
From a market standpoint, one of IonQ's competitors, Rigetti Computing (NASDAQ: RGTI), notes that it expects a $15 billion to $30 billion annual market to emerge between 2030 and 2040. IonQ believes the total addressable quantum computing market will reach about $87 billion by 2035 (that's a cumulative figure). Nvidia generated $41 billion in data center GPU sales alone during Q2, so it's clear that Nvidia will likely generate more money than these quantum computing companies even a decade from now.
Furthermore, there's no guarantee that IonQ's approach will be the ultimate winner. While IonQ is a leader now, it's possible that it loses that leadership position over the net in the future.
Additionally, there are many potential competitors in the quantum computing arms race, and companies like Alphabet have nearly unlimited resources to spend on this technology, unlike IonQ. It's an uphill battle for IonQ, but if it pans out, it will still make investors a ton of money, although there's no guarantee of success.
Between Nvidia and IonQ, I think there's a clear winner as to which stock is the better AI computing play: Nvidia. Nvidia is still rapidly growing and making money from each GPU it sells. We're still a ways out from quantum computing becoming relevant, even though IonQ looks like a promising pick in this space. IonQ is a long-shot investment that could pay off, but if the AI market is as large as Nvidia says it is (alongside many other companies involved in this space), Nvidia will pay off.

Is IonQ or Nvidia the Better AI Computing Stock to Buy Now?

Key Points
Alphabet's technology is best-in-class.
Alphabet has massive cash flow to finance its quantum computing investments.
Quantum computing stocks were all the rage on Wall Street up until a few days ago. Now, quantum computing stocks have sustained heavy losses as investors readjust their expectations of when quantum computing could become a viable alternative.
The most popular quantum computing stocks by far are pure plays like IonQ (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), and D-Wave Quantum (NYSE: QBTS). However, these three are long-shot investments that may or may not pay off.

Instead of this trio, I think investors should look at an under-the-radar quantum computing alternative: Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL). While Alphabet may not be an under-the-radar company in general (it's the fourth-largest company in the world by market cap), it has mostly been forgotten about in the quantum computing realm. I've got three reasons investors should consider Alphabet as a quantum computing investment, and I wouldn't be surprised to see Alphabet outperform some of its quantum computing pure-play competition over the next few years.
1. Alphabet is a leader in quantum computing
While many point toward the quantum computing pure plays as being leaders in the quantum computing industry, Alphabet challenged that notion a few days ago when it released some of the latest results of its Willow quantum computing chip.
On Oct. 22, Google announced that its Willow quantum computing chip successfully ran a verifiable algorithm on its quantum computer at a speed 13,000 times faster than a traditional computer. It did this on a 105-qubit system, one of the largest and most powerful currently known. For reference, Rigetti Computing made headlines when two companies purchased its Novera quantum computing system, which has four sets of nine qubits.
Alphabet is clearly a leader in this field, and it has the results to prove it. Alphabet may wipe the floor with its competition, making it the smartest quantum computing company to invest in.
2. Alphabet has plenty of cash to fund its quantum computing investments
Unlike its quantum computing pure-play competition, Alphabet has nearly unlimited resources to pour into its quantum computing aspirations. This isn't a cheap technology by any means, so having massive cash flow to fund research is critical. Over the past 12 months, Alphabet has generated around $66 billion in free cash flow.
It's using a huge chunk of that for building out artificial intelligence data centers, but it could also shift those funds to finance its quantum aspirations as well. For reference, IonQ's revenue for Q2 totaled $20.7 million, and it currently has just over half a billion in cash and short-term investments on its balance sheet.
While David and Goliath stories exist for a reason, this seems to be one where David doesn't have enough funding to compete with the Goliath in the industry. I think this gives Alphabet a serious competitive advantage, and it's one that the pure plays may not be able to overcome.
3. Alphabet isn't an all-or-nothing quantum computing play
Lastly, there's no guarantee that quantum computing will work out. Although many companies are starting to prove meaningful applications, it's unknown how large the real-world application truly is for quantum technology. Additionally, these pure-play quantum computing investments are just that, pure plays. It's an all-or-nothing bet that they will achieve quantum computing supremacy. If they don't succeed, there's a significant chance of the investment going to $0.
Alphabet isn't like that. It has a strong advertising business based on its Google family of products, as well as a strong cloud computing offering. If quantum computing doesn't pan out or another competitor beats out Alphabet, it will still be a viable investment. This significantly reduces the risk of the overall investment, making me more confident in backing Alphabet as a quantum computing investment than any other stock in this industry.

3 Reasons to Buy This Under-the-Radar Quantum Computing Stock Today

Key Points
The long-term impact of quantum computing could be several trillion dollars.
IonQ has been developing its technology for 30 years.
The company says its push into quantum networking will double the company's addressable market.
Quantum computing is expected to be the next wave of innovation beyond artificial intelligence (AI) that could lead to major technological breakthroughs that traditional computers are not capable of executing. The enthusiasm for its potential has sent share prices of IonQ (NYSE: IONQ) soaring more than 300% over the past year.
Given that steep (and quick) rise, it's natural for investors to feel like they have missed their chance with such a stock, but great companies don't just double or triple; they deliver multibagger returns over decades. IonQ might just be getting started.

IonQ just recently made a huge breakthrough that could lead to tremendous growth over the next decade and beyond.
IonQ's opportunity could be bigger than anyone thinks
IonQ has been developing quantum computing for 30 years, and it could be on the verge of accelerating the commercialization of its technology. The goal is to expand into quantum networking, which could unlock tremendous upside for the company's revenue.
In September, IonQ announced it had successfully transformed visible-wavelength photons into telecom wavelengths. This paves the way for isolated quantum computers separated by long distances to link together over existing fiber optic networks, ultimately paving the way for a quantum internet.
The long-term economic impact of quantum computing is estimated to eventually reach into the trillions. He didn't provide a specific estimate, but CEO Niccolo de Masi recently said quantum networking will at least double the company's market opportunity.
Given the transformative effect this could have on the economy, IonQ's current $18 billion market cap doesn't appear all that expensive, but it is currently trading at a very high multiple of its trailing revenue. Investors will have to be prepared for volatility in the share price, but for an investor who can patiently hold the stock for 10 years, it is not too late to invest in IonQ.

Key Points
Google just announced a new breakthrough with its Willow quantum chip.
Pure-play quantum stocks fell on the news.
Investors seem to be sensing a change in the sector.
Quantum computing stocks have been some of the biggest winners over the last year.
In fact, it's hard to find a group of stocks that have done better than the four development-stage companies: IonQ (NYSE: IONQ), D-Wave Quantum (NYSE: QBTS), Rigetti Computing (NASDAQ: RGTI), and Quantum Computing (NASDAQ: QUBT). As you can see from the chart below, these four stocks have skyrocketed over the last year.

A basket of all four of these stocks would have returned a whopping 1,600% over the last year even though they still have minimal revenue.
While the pure-play quantum computing companies have yet to generate significant financial results, excitement is building for the new technology. In the wake of the breakthrough in artificial intelligence (AI), investors are looking for the next potentially disruptive technology, and quantum computing has caught their eye.
Quantum computing, based on quantum physics, is much more powerful than traditional computing. Attention on this new technology has soared as a number of tech luminaries, including Nvidia CEO Jensen Huang, have acknowledged that useful quantum computing could be here sooner than expected. A milestone achieved by Alphabet's (NASDAQ: GOOG) (NASDAQ: GOOGL) Willow quantum chip last December also helped drive interest in quantum computing and sent those four stocks soaring.
Now, it seems that Google has taken another step forward in its quantum ambitions.
Google's latest quantum breakthrough
Nearly a year ago, Google said that its Willow quantum chip achieved a benchmark computation in less than five minutes that would have taken one of today's fastest supercomputers 10 septillion years.
On Wednesday, Google said that Willow had demonstrated "the first-ever algorithm to achieve verifiable quantum advantage on hardware." Google said that the breakthrough is a significant step toward the first real-world application for the technology.
The algorithm, which it calls Quantum Echoes, is useful in learning how systems in nature are structured, including molecules, magnets, and black holes. Willow also runs the algorithm 13,000 times faster than a comparable algorithm would on one of the world's fastest supercomputers. It's the first time in history that a quantum computer has run a verifiable algorithm faster than conventional supercomputers.
In a separate experiment, Google also developed a new technique it calls a "molecular ruler" that can measure longer distances than conventional methods used today.
What it means for pure-play quantum stocks
As you might expect, the pure-play quantum computing stocks didn't react well to the news, as the development seems to show them getting left behind by Google. All four of the stocks were down at least 7% on Wednesday.
For all the excitement around the quantum computing stocks, Alphabet still looks like the clear leader in the industry. Not only is it making a significant scientific achievement with Willow, but the chip also has more qubits, a measure of quantum computing power, than any quantum processors used by the smaller companies.
Willow has 105 qubits, while IonQ's biggest processor, Forte, has 36 qubits. IonQ and its peers are working on developing computers with thousands of qubits, but Google clearly has the lead for now.
What's also notable about Wednesday's sell-off is that these stocks had the opposite response when the original Willow news was announced last December. Quantum computing stocks are much more valuable now, but investors no longer see Google pioneering a market that smaller operators will benefit from. Instead, they seem to sense that a bubble has been created and that Google's technological achievements don't directly benefit companies like IonQ.
The best quantum computing stock to buy
At this stage, Alphabet looks like the best quantum computing stock to buy, hands down. At a market cap of around $3 trillion, it won't deliver the kind of multibagging returns that the pure plays are capable of, but it's the clear technological leader in quantum computing right now. It has the deep pockets and business relationships to continue funding its ambition and to find customers, and it has a track record of success in emerging technologies with products like Waymo autonomous vehicles and its Gemini AI chatbot.
That may be disappointing to investors in the earlier-stage companies, but these four companies now have a combined market cap of nearly $50 billion with little in the way of revenue.
If you're looking for a smart quantum computing stock to buy, Alphabet is the best choice. Not only is it the pacesetter in technological development in quantum computing, but it also has much less downside risk than stocks like IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing.
It's already one of the most profitable companies in the world. Quantum computing could make it even more powerful.

What's the Best Quantum Computing Stock to Buy? It Just Became Crystal Clear (Hint: It's Not IonQ).

Key Points
The Trump administration is reportedly in discussions with quantum computing companies D-Wave, IonQ, and Rigetti about taking an equity stake in exchange for federal funding.
Grand View Research estimates businesses will spend 600 times more on cloud computing (versus quantum computing) in 2030.
D-Wave, IonQ, and Rigetti burned between two and six times as much cash as they earned in revenue during the past year, and all three stocks trade at absurdly expensive valuations.
The Trump administration has already taken a stake in Intel and three minerals companies, and it recently turned its attention to quantum computing. The Commerce Department is reportedly in talks with D-Wave Quantum (NYSE: QBTS), IonQ (NYSE: IONQ), and Rigetti Computing (NASDAQ: RGTI) about the government receiving an equity position in exchange for funding, according to The Wall Street Journal.

Quantum computing may be a decade away (or more) from mainstream utility
Quantum computers cannot speed up everyday computing tasks, but they can solve some problems that would be very time-consuming (if not impossible) for classical computers. For instance, quantum computers are particularly good at optimizing processes with many complex variables, which has use cases across drug discovery, finance, materials science, and supply chain management.
However, quantum computing is still experimental and most organizations would get little (if any) value from the technology today. Quantum computers are not only expensive, but also difficult to scale and limited by high error rates. Alphabet CEO Sundar Pichai recently said practical applications are at least five to 10 years away, and he compared the state of the industry to artificial intelligence in the 2010s.
Nvidia CEO Jensen Huang has made similar comments, estimating commercially useful quantum computers could be two decades away. Investors should consider this context: The cloud computing market is forecast to reach $2.4 trillion by 2030, but the quantum computing industry will be worth just $4 billion (600 times less), according to Grand View Research.
Valuations across the quantum computing industry are sky-high
D-Wave, IonQ, and Rigetti are deeply unprofitable. Over the past year, the first two companies burned twice as much cash as they earned in revenue, and Rigetti burned six times as much cash. The other problem is their valuations. All three stocks trade at price-to-sales (PS) ratios that are nonsensical when compared to forecasted sales growth.
D-Wave Quantum currently trades at 500 time sales. Wall Street expects sales to grow at 57% annually to reach $109 million in 2028. If that happens, the stock would still trade at 103 times sales even with no share price appreciation.
IonQ currently trades at 340 times sales. Wall Street expects sales to grow at 90% annually to reach $492 million in 2028. If that happens, the stock would still trade at 36 times sales even with no share price appreciation.
Rigetti Computing current trades at 1,590 times sales. Wall Street expects sales to grow at 90% annually to reach $75 million in 2028. If that happens, the stock would still trade at 168 times sales even with no share price appreciation.
Here is context for those valuations: Currently, 498 stocks in the S&P 500 have PS multiples below 35. That means D-Wave, IonQ, and Rigetti would still be very expensive three-plus years from now even if their stock prices stay the same. And even that disappointing outcome is contingent upon these companies meeting very high expectations on Wall Street.
Better buying opportunities will likely to arise in the future
Quantum computing promises to be a transformative technology. But with mainstream use cases still several years away and valuations inflated across the industry, D-Wave, IonQ, and Rigetti are almost certainly in a bubble right now. The stocks may keep climbing in the near term, especially if the Trump administration takes a stake, but a major crash is almost unavoidable at some point.
Anecdotally, Nvidia dominates the artificial intelligence infrastructure market today, but its share price dropped more than 50% on three separate occasions during the last 15 years. All three crashes were fantastic buying opportunities in hindsight. So, investors who want exposure to quantum computing should wait for a similar opportunity with D-Wave, IonQ, and/or Rigetti.
Should you invest $1,000 in Rigetti Computing right now?
Before you buy stock in Rigetti Computing, consider this:

Quantum Computing Stocks D-Wave, IonQ, and Rigetti Talk With Trump Administration About Equity Stakes. Is It Time to Buy?

Key Points
Shares of IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. have surged by up to 2,720% over the trailing year.
Though quantum computing pure-play stocks are popular among investors, they're rife with historical red flags.
There's a far more "magnificent" way to gain exposure to the evolution of quantum computing without the outsize risk of pure-play stocks.
Over the last three years, the evolution of artificial intelligence (AI) has fueled the rally on Wall Street. However, AI isn't the only can't-miss trend that has investors eager to open their wallets and press the buy button in their brokerage accounts.
Arguably nothing has been hotter than quantum computing pure-play stocks in 2025. Shares of IonQ (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), D-Wave Quantum (NYSE: QBTS), and Quantum Computing Inc. (NASDAQ: QUBT), have respectively skyrocketed higher by 276%, 2,720%, 2,150%, and 1,200% over the trailing 12-month period, as of the closing bell on Oct. 22.

Quantum computing uses specialized computers and the theories of quantum mechanics to solve complex problems that existing computers aren't capable of solving. Quantum computers may have the ability to speed up AI algorithm learning capabilities, and can narrow down best courses of action for drug developers using molecular simulations, to name a few real-world applications.
According to online publication The Quantum Insider, this technology could create $1 trillion in global economic value by 2035. A figure this large would support a long list of potential winners.
However, relying on Wall Street's pure-play quantum computing stocks may not be the smartest way to invest in the evolution of this technology. Instead, there's a far more "magnificent" way to gain exposure to quantum computing and safely grow your wealth.
Quantum computing pure-play stocks have well-defined shortcomings
While there have been bright spots for these quantum computing stocks, including IonQ and Rigetti having their respective computers used by Amazon (NASDAQ: AMZN) in its quantum cloud computing service known as Braket, there are far more headwinds than tailwinds for this quartet at the moment.
History might be the biggest hurdle IonQ, Rigetti, D-Wave, and Quantum Computing Inc. would need to overcome.
For more than 30 years, every game-changing technology or hyped innovation has worked its way through an early stage bubble-bursting event. From the internet to hyped innovations like 3D printing, blockchain technology, and the metaverse, investors have persistently overestimated how quickly consumers and/or businesses would adopt, utilize, and optimize a new technology. By overshooting, investors expose themselves -- and the leading stocks involved with these trends -- to eventual disappointment. Nothing suggests that quantum computing stocks will avoid this same fate.
Historical precedent also tells us that quantum computing stocks are richly valued. As of the closing bell on Oct. 22, their respective trailing 12-month (TTM) price-to-sales (P/S) ratios are:
IonQ: 241
Rigetti Computing: 1,154
D-Wave Quantum: 313
Quantum Computing Inc.: 7,013
For context, companies that led previous game-changing innovative trends often topped out with P/S ratios in the range of 30 to 40. No industry leader has ever been able to sustain a TTM P/S ratio of 30 for any extended period, let alone TTM P/S ratios ranging from 241 to north of 7,000!
With an unfavorable risk-versus-reward profile for IonQ, Rigetti, D-Wave, and Quantum Computing Inc., the smartest way to gain exposure to a coming quantum computing revolution is through the "Magnificent Seven."
Ancillary exposure through the Mag 7 is a genius way to wager on quantum computing
Although the applications for quantum computers and quantum hardware are exciting, this is a technology that's a very long way from maturing. Aside from Amazon offering access to IonQ's and Rigetti's quantum computers through Braket on Amazon Web Services (AWS), and Microsoft (NASDAQ: MSFT) offering quantum services on its cloud infrastructure service platform via Azure Quantum, it's not clear if this technology is being adopted on any broad commercial scale.
Furthermore, there's not any clear evidence that quantum computing solutions are being optimized as of yet, or are helping businesses using these solutions generate a recurring profit. In other words, it can't be emphasized enough how early this technology is in the commercialization and evolutionary process.
While quantum computers evolve and become commercialized, IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. are likely to lose money hand over fist. They'll also be issuing common stock and/or debt (if accessible) to bolster their balance sheets amid ongoing investments and operating losses.
In comparison, all members of the Magnificent Seven have established and well-defined competitive advantages -- sometimes in more than one industry. For example, Amazon is the undisputed leader in e-commerce, and the leader in global cloud infrastructure service spending with AWS. All members of the Mag 7 also have sizable piles of cash, cash equivalents, and marketable securities, and most are generating more cash from operations than they know what to do with.
When new technologies and game-changing innovations come along, Magnificent Seven businesses have demonstrated a desire to get their piece of the pie.
For instance, Meta Platforms (NASDAQ: META) has put tens of billions of dollars to work in the metaverse, which is the 3D virtual world where users can interact with each other and their surroundings. Meta CEO Mark Zuckerberg is well aware that these investments may not pay off for multiple years, given that the metaverse needs time to develop and mature. Meta is one of the few publicly traded companies with enough cash and operating cash flow to make these aggressive investments without hurting its bottom line or harming future innovation in other areas.
We've also witnessed Microsoft and Alphabet (NASDAQ: GOOGL)(NASDAQ: GOOG) introduce quantum computing chips. Last week, Alphabet confirmed that its Willow chip ran a quantum algorithm that operated 13,000 times faster than the quickest supercomputers on the planet. Meanwhile, Microsoft's Majorana 1 quantum processing unit was introduced in mid-February.
Though quantum hardware may be years away from generating meaningful revenue, Microsoft and Alphabet (along with other Mag 7 members) have plenty of other operating segments to grow their respective sales and profits in the meantime while investors wait.
