How to Invest in Quantum Computing Stocks and Funds

What quantum computing stocks and funds actually are

Quantum computing is a real technology in development, not a speculative concept. Companies are building quantum computers and the infrastructure around them. You can own shares in those companies through individual stocks or through funds that hold multiple quantum-related businesses.

The catch: quantum computing is still in early stages. Most companies in this space are not yet profitable. You are betting on future demand and technological breakthroughs that may or may not happen on the timeline the market expects. This is higher-risk investing than buying shares in an established tech company with current revenue.

There are three main routes: buy individual stocks of quantum computing companies, buy exchange-traded funds (ETFs) that focus on quantum technology, or buy shares in larger tech companies that have quantum divisions alongside their main business. Each has different risk and diversification profiles.

Key Takeaways

• Quantum computing companies exist as standalone businesses and as divisions within larger tech firms, and you can own either through stocks or sector-focused ETFs.
• Most pure-play quantum companies are not yet profitable, so stock prices move on investor sentiment about future breakthroughs rather than current earnings.
• ETFs that track quantum computing reduce the risk of betting on a single company but still expose you to the risk that the entire sector underperforms expectations.
• Larger tech companies like IBM and Microsoft have quantum divisions but generate most revenue elsewhere, so their stock price is not driven by quantum progress alone.
• Quantum computing stocks are volatile and suitable only for investors who can tolerate significant short-term losses without needing the money soon.

Individual quantum computing stocks and what they do

The main publicly traded companies focused on quantum computing include IonQ, Rigetti Computing, D-Wave Systems, and Quantum Computing Inc. Each has a different approach to building quantum hardware or software. IonQ uses trapped-ion technology. D-Wave focuses on quantum annealing for optimization problems. Rigetti builds superconducting quantum processors. These are not interchangeable bets—they are bets on different technical paths, and some paths may prove more commercially viable than others.

IBM and Microsoft also have quantum computing divisions, but they are divisions, not the whole company. IBM's quantum business is part of its broader infrastructure and software offerings. Microsoft's quantum effort is similarly one piece of a much larger business. When you buy IBM or Microsoft stock, you are buying the entire company, and quantum progress is one factor among many affecting the stock price.

Before buying any individual stock, read the company's latest quarterly earnings report and investor presentation. These documents explain what the company has actually built, what customers are paying for it (if any), and what the company's path to profitability looks like. Many quantum companies have no revenue yet or revenue measured in millions while burning tens of millions annually. That is not inherently disqualifying—many successful tech companies operated that way early on—but it means you are funding research, not buying a cash-generating business.

Quantum computing ETFs and sector funds

Several ETFs track quantum computing and related technologies. The Defiance Quantum ETF (ticker QTUM) and the Roundhill Quantum Computing ETF (ticker QCMP) are two examples. These funds hold a basket of companies involved in quantum hardware, software, and supporting infrastructure. By owning the fund, you own a piece of many quantum bets at once, which reduces the risk that you picked the wrong company but does not reduce the risk that the sector as a whole disappoints.

ETFs are simpler to buy than individual stocks—you purchase them through any brokerage account the same way you would buy a stock—but you should still read the fund's prospectus to understand which companies it holds and how much of the fund's assets go to each one. Some quantum ETFs are heavily weighted toward a few large holdings; others spread the money more evenly. The fund's expense ratio (the annual fee charged as a percentage of assets) also matters. A 0.5% annual fee is typical for sector ETFs; some charge more.

Check the fund's holdings list before you buy. If the fund holds mostly large tech companies with small quantum divisions, you are not really getting a quantum bet—you are getting a tech fund with a quantum label. If it holds mostly unprofitable early-stage quantum companies, you are taking on concentrated risk. Neither is wrong, but they are different bets.

How quantum computing stocks move and why they are volatile

Quantum computing stocks do not move on earnings reports the way mature tech stocks do, because most quantum companies have no earnings. They move on announcements about technical breakthroughs, funding rounds, partnerships with large companies, or shifts in investor sentiment about whether quantum computing will ever be commercially useful.

A single announcement—that a company achieved a new record for quantum processor stability, or that a major corporation signed a contract to use a quantum service—can cause the stock to jump or fall sharply. Conversely, a competitor's breakthrough or a published paper suggesting a technical approach will not work can send prices down. This volatility is much higher than the stock market as a whole.

This volatility means quantum computing stocks are not suitable for money you need within the next few years or money you cannot afford to lose. They are suitable only for investors with a long time horizon, a high risk tolerance, and a portfolio large enough that a quantum position is a small percentage of the total. A common rule of thumb is to limit speculative positions like this to 5% or less of your total portfolio.

Where to buy quantum computing stocks and ETFs

You buy quantum computing stocks and ETFs through the same brokerage account you would use for any stock investment. Open an account with a major brokerage—Fidelity, Charles Schwab, Vanguard, E-Trade, or others—and search for the ticker symbol of the stock or ETF you want to buy. Place a market order (buy at the current price) or a limit order (buy only if the price falls to a level you specify). The transaction settles in two business days.

Do not use a brokerage that charges per-trade commissions; most major brokerages offer commission-free stock and ETF trades. Do not use a brokerage that restricts which stocks you can buy or that requires a minimum account balance you cannot meet. Stick to regulated brokerages registered with the Securities and Exchange Commission (SEC).

Tax treatment of quantum computing investments

If you hold quantum stocks or ETFs in a regular taxable brokerage account, you owe capital gains tax when you sell at a profit. If you hold them for more than one year before selling, the gain is taxed as long-term capital gains, which is usually taxed at a lower rate than short-term gains. If you hold them for one year or less, the gain is taxed as ordinary income at your regular tax rate.

If you hold quantum stocks or ETFs in a tax-advantaged account—a 401(k), IRA, or similar—you do not owe tax on gains until you withdraw the money from the account (or in the case of a Roth IRA, possibly never). This makes tax-advantaged accounts a good place for volatile, speculative investments like quantum stocks, because you avoid the tax hit if the investment loses value and then recovers.

Alternatives to direct quantum stock ownership

If you want exposure to quantum computing but do not want to pick individual stocks or quantum-specific ETFs, you can buy a broad technology ETF that holds some quantum-related companies alongside many others. An S&P 500 index fund holds IBM and Microsoft, both of which have quantum divisions. A technology sector ETF holds a wider range of tech companies, some of which work on quantum problems. This approach gives you quantum exposure without concentrating your bet on the sector.

You can also wait. Quantum computing is not going anywhere. If the technology matures and becomes commercially important, more companies will enter the space, more ETFs will launch, and the investment landscape will be clearer. There is no penalty for waiting until you understand the sector better or until the technology is further along.

Frequently Asked Questions

Is quantum computing a real technology or hype?

Quantum computing is real technology in active development by major companies and research institutions. IBM, Google, Microsoft, and others have built working quantum computers. The question is not whether quantum computing exists, but whether it will solve commercially important problems faster than classical computers and whether that will happen soon enough to justify current stock prices.

Can I buy quantum computing stocks in my 401(k) or IRA?

Yes, if your 401(k) or IRA is a self-directed account that allows you to choose individual stocks and ETFs. Most employer 401(k) plans offer only a limited menu of mutual funds and ETFs, so you may not have access to quantum-specific funds. An IRA through a brokerage like Fidelity or Schwab gives you access to any publicly traded stock or ETF.

What is the difference between quantum computing stocks and quantum computing ETFs?

Individual stocks let you bet on one company's success or failure; if that company's technology works and becomes valuable, the stock can rise sharply, but if the company fails, you lose your investment. ETFs spread your money across many companies, so the failure of one does not wipe out your position, but you also do not benefit as much if one company becomes hugely successful.

How much of my portfolio should I put in quantum computing?

Quantum computing is a speculative, high-risk sector. Most financial advisors suggest limiting speculative positions to 5% or less of your total portfolio. If you cannot afford to lose that amount without affecting your financial goals, the position is too large.

Should I buy quantum stocks now or wait?

That depends on your risk tolerance, time horizon, and conviction about the technology. If you believe quantum computing will be important and you can tolerate significant short-term losses, now is a reasonable time to start a small position. If you are uncertain or need the money within five years, waiting is also reasonable. There is no single right answer.
