Quantum computing stocks and funds are the most practical entry point for most investors
If you want to invest money in quantum computing, you have three realistic paths: buy shares in established companies that are building quantum hardware or software, buy shares in funds that hold a basket of quantum-related companies, or invest directly in private quantum startups if you have significant capital and can meet accreditation requirements. Most individual investors use the first two routes because they require no special status and you can start with small amounts.
Quantum computing is still in early stages—no quantum computer has yet solved a real-world problem faster than a classical computer can. That means the field is speculative. Companies working on quantum hardware (IBM, IonQ, Rigetti) are not yet profitable from quantum work itself. They survive on venture funding, government contracts, or revenue from other business lines. Before you invest any money, understand that you are betting on the technology maturing over years or decades, not on when ready returns.
Key Takeaways
- Quantum computing stocks trade on regular exchanges like NASDAQ and NYSE, and you can buy them through any brokerage account without special permission.
- Quantum-focused exchange-traded funds (ETFs) let you own shares in multiple quantum companies at once, spreading your risk across the sector.
- Private quantum startups require you to be an accredited investor (usually $200,000+ annual income or $1 million in assets) and accept illiquidity—your money may be locked in for years.
- Quantum computing remains experimental; no quantum computer has yet outperformed classical computers on practical problems, so treat these investments as high-risk and long-term.
- Research the company's funding stage, revenue model, and technical approach before investing, because many quantum firms have no clear path to profitability.
Public quantum computing stocks you can buy through any brokerage
IBM (ticker: IBM) is the largest and most established player. IBM has been researching quantum for decades and now offers cloud access to quantum processors through IBM Quantum. The company is not primarily a quantum business—most revenue comes from software and services—but quantum is a growing division. You buy IBM stock the same way you buy any stock: through a brokerage account (Fidelity, Charles Schwab, E-Trade, or others), with no minimum investment beyond what the brokerage requires.
IonQ (ticker: IONQ) is a pure-play quantum hardware company. It went public in 2021 through a merger and trades on NASDAQ. IonQ builds quantum computers using trapped-ion technology and sells access to them through cloud platforms. The company has no revenue yet and operates at a loss, so this is a speculative bet on the technology working at scale.
Rigetti Computing (ticker: RGTI) also trades publicly and builds superconducting quantum processors. Like IonQ, Rigetti is pre-revenue and funded by venture capital and government grants. Both IonQ and Rigetti are much smaller and riskier than IBM.
Other companies with quantum divisions include Google (ticker: GOOGL), which has a quantum AI lab but is not a quantum-focused company, and Microsoft (ticker: MSFT), which is developing quantum software and hardware but derives almost all revenue elsewhere. If you buy Google or Microsoft for quantum exposure, you are mostly buying a diversified tech company that happens to have a quantum team.
Quantum-focused ETFs that hold multiple companies
An exchange-traded fund (ETF) is a basket of stocks that trades like a single stock. Several ETFs focus on quantum computing and related fields. The Defiance Quantum ETF (ticker: QTUM) holds companies involved in quantum computing, quantum networking, and quantum sensing. The Roundhill Quantum Computing ETF (ticker: QCMP) takes a similar approach. These funds typically hold 30 to 50 stocks, including IBM, IonQ, Rigetti, and companies that supply materials or software to the quantum industry.
The advantage of an ETF is diversification: if one quantum company fails, your entire investment does not disappear. The disadvantage is that you own a slice of many companies, some of which may never produce quantum revenue. You also pay an annual fee (usually 0.5% to 0.75% of your holdings per year) to the fund manager.
You buy quantum ETFs the same way you buy individual stocks—through any brokerage account. There is no minimum investment beyond what the brokerage requires, and you can sell anytime the market is open.
Private quantum startups and venture capital routes
If you have substantial wealth, you can invest directly in private quantum startups through venture capital funds or equity crowdfunding platforms. Companies like Atom Computing, PsiQuantum, and D-Wave (which is now public but was private for years) have raised hundreds of millions from venture investors.
To invest in private quantum companies, you typically must be an accredited investor. The SEC defines this as someone with annual income above $200,000 (or $300,000 with a spouse) for the past two years, or net worth above $1 million excluding your home. You prove this through your brokerage or the investment platform.
Private investments are illiquid, meaning you cannot sell your shares easily. Your money may be locked in for 5 to 10 years or longer while the company develops its technology and seeks an exit (acquisition or IPO). If the company fails, you lose your investment with no public market to sell into.
Platforms like AngelList and Forge let accredited investors buy shares in private companies, including some quantum startups. You can also invest through venture capital funds that focus on quantum, though these typically require larger minimums ($25,000 to $100,000+).
Understanding the quantum computing business models
Quantum companies make money in different ways, and understanding this helps you evaluate the investment. Hardware companies like IonQ and Rigetti build the quantum computers themselves and sell access through cloud platforms—customers pay per use or per subscription. This model is similar to how AWS sells cloud computing, but quantum is far less mature.
Software and tools companies build the programming languages, algorithms, and applications that run on quantum hardware. Companies like Zapata Computing and Cambridge Quantum (now part of Quantinuum) focus here. Their revenue comes from licensing software or consulting.
Hybrid companies like IBM offer both hardware and software, plus classical computing services. IBM's quantum division is a small part of a much larger business, which gives it stability but also means quantum is not the main driver of the stock price.
The critical question for any quantum investment is: what is the path to profitability? Most pure-play quantum companies have no clear answer yet. They are betting that quantum computers will become useful enough that customers will pay for access. That could happen in 5 years or 20 years—or it might not happen at all if the technical barriers prove insurmountable.
How to research quantum companies before investing
Start with the company's latest earnings report or investor presentation. For public companies, these are filed with the SEC and available free on the company's investor relations website or on SEC.gov. Look for revenue (do they have any?), funding sources (venture capital, government grants, or profitable operations?), and what they are actually building.
Read the company's technical papers and announcements. Quantum is a field where marketing often outpaces reality. A company might claim a breakthrough in quantum error correction, but the paper might show a tiny proof-of-concept in a lab. Understand the difference between a lab result and a product customers can use.
Check who is funding the company. If a quantum startup is funded by serious venture firms (Sequoia, Andreessen Horowitz, Khosla Ventures) or government agencies (DARPA, the Department of Energy), that is a signal that experts believe in the technology. It is not a may provide, but it is worth noting.
Look at the team. Quantum computing requires deep informed in physics, mathematics, and engineering. If the founders and leadership team have published research in quantum computing or worked at established quantum labs, that is a positive sign. If they are career entrepreneurs with no quantum background, that is a red flag.
Tax and account considerations for quantum investments
Quantum stocks and ETFs held in a regular taxable brokerage account are subject to capital gains tax. If you hold them for more than one year before selling, you pay long-term capital gains tax (usually 15% or 20% depending on income). If you hold them for less than one year, you pay short-term capital gains tax at your ordinary income rate, which is higher.
If you hold quantum stocks or ETFs in a retirement account (401k, IRA, Roth IRA), you do not pay capital gains tax when you sell them inside the account. You only pay tax when you withdraw money from the account (or never, in the case of a Roth IRA). This makes retirement accounts a tax-efficient way to hold speculative investments like quantum stocks.
Private equity investments in quantum startups have different tax treatment. You may be able to deduct losses if the investment fails, and some venture funds offer tax advantages like opportunity zone benefits. Consult a tax professional before investing in private quantum companies.
Frequently Asked Questions
Is quantum computing a good investment right now?
Quantum computing is speculative and early-stage. No quantum computer has yet solved a practical problem faster than a classical computer. If you invest, treat it as a long-term, high-risk bet on the technology maturing over many years. Do not invest money you cannot afford to lose.
Should I buy individual quantum stocks or a quantum ETF?
An ETF spreads your risk across many companies, which is safer if you are unsure which quantum company will succeed. Individual stocks offer higher upside if you pick a winner, but higher downside if you pick wrong. Most investors benefit from the diversification of an ETF.
Can I invest in quantum computing with a small amount of money?
Yes. You can buy a single share of a quantum stock or ETF through most brokerages with no minimum investment. Some brokerages allow fractional shares, so you can invest even smaller amounts. Private quantum startups, however, typically require accreditation and larger minimums.
What is the difference between IBM quantum and a pure-play quantum company like IonQ?
IBM is a diversified technology company where quantum is one division among many. IonQ is a startup focused entirely on quantum hardware. IBM is less risky because it has other revenue sources, but IonQ offers more direct exposure to quantum technology. Your choice depends on your risk tolerance.
How do I know if a quantum company is legitimate?
Check whether the company is publicly traded (SEC filings are public), who funds it (reputable venture firms or government agencies), and whether the leadership has published quantum research. Be skeptical of companies making grand claims without peer-reviewed papers or customer contracts to back them up.
