Are quantum stocks a good buy?

At this point, there is no established leader in quantum computing. Dozens of companies, including several tech giants, are researching its potential and experimenting with real-world uses. Developing quantum hardware that accurately performs computations and meets reasonable return-on-investment thresholds is still ongoing. So, there are no clear long-term winners to invest in at this point, apart from the established tech giants who can treat quantum computing as a promising side gig. Smaller quantum computing experts such as D-Wave, Rigetti, and IonQ might deliver great long-term returns -- but they also face significant risks without a financial safety net. All things considered, quantum computing is best approached with care. Established winners and exchange-traded funds (ETFs) can limit your risks, and direct bets on the smaller experts in this field should be fairly small. Those are high-risk, high-reward long-term bets.

How does quantum computing affect the stock market?

So far, it's mostly hype cycles and volatility. It's a different story in the long term, though. Quantum could revolutionize finance through faster risk modeling, portfolio optimization, and cracking current encryption. But it's not there yet. Today, it's a speculative bet on tomorrow's infrastructure.

Does Warren Buffett invest in quantum computing?

Berkshire Hathaway's portfolio does not include any pure-play quantum computing companies, such as IonQ, Rigetti, or D-Wave. The closest connection is Berkshire's stake in Apple (NASDAQ: AAPL), which has conducted research into quantum-resistant cryptography. Furthermore, Warren Buffett is a private investor these days. Buffett retired as Berkshire's CEO in 2025, so his future influence on the company's investments is unclear. During his tenure, he generally avoided early-stage technology with unproven business models. So far, quantum computing falls in that category.

What company has the most quantum computing patents?

IBM is the front-runner, with more than 2,500 patent filings in quantum computing. Runner-up Alphabet has some catching up to do, having filed 1,500 quantum patents as of January 2026.

Can I invest in quantum computing?

Yes, but only a small handful of quantum computing pure plays exist at this point, and they all lose money. However, investors who want a more balanced bet on the future of quantum computing can invest in the shares of tech giants with an interest in the space.

Are quantum computing stocks risky?

Quantum systems are slowly becoming more usable for solving real-world computing problems. However, it will still take many years to commercialize this industry meaningfully. Tech giants like Microsoft, Alphabet, and Nvidia offer possibilities for this exciting field, while smaller specialists such as D-Wave and IonQ are more direct bets on this technology. The big names are safer, while the small ones carry greater financial risks.

Is there a quantum computing ETF?

Yes. The Defiance Quantum Computing ETF has been around since 2018 and mirrors the components of the BlueStar Machine Learning and Quantum Computing Index. The equal-weighted stock list includes tech titans and quantum computing specialists. The fund was a strong performer in 2025, reflecting the surging market interest in quantum computing stocks.

IonQ develops quantum computing hardware and is the first to have its systems available across all major public cloud services. It plans to build a network of quantum computers accessible via the cloud and is targeting rapid growth in 2026 as researchers begin using its hardware at a greater scale.

The company partners with Microsoft (MSFT +3.04%), Amazon (AMZN -1.19%) Web Services (AWS), and Alphabet's (GOOG -1.03%) (GOOGL -1.15%) Google Cloud. Japanese telecommunications company and tech investor SoftBank Group (SFTBF -4.26%) has also invested in IonQ.

SoftBank is partnering with IonQ to bring quantum computing power to the many other tech companies in its portfolio. IonQ's most powerful computer, Aria, has been available via an AWS service since May 2023.

IonQ has generated minimal revenue so far and is not yet profitable. It will need to continue spending heavily to develop its products and business for at least a few more years.

Investing in this start-up is a speculative play. If IonQ's research efforts are successful, the stock could be a profitable way to invest in quantum computing, but investors should act with prudence. This is still a start-up business, and its valuation is often sky-high.
