In this article, we will look at the 10 Best Quantum Computing Stocks to Buy and Hold Forever.
The quantum computing sector came under the spotlight recently in May 2026 after the US government announced a $2 billion grant for nine companies in the sector. According to CNBC, The Wall Street Journal first broke the story, which highlighted that the National Institute of Standards and Technology signed letters of intent with the companies and took a minority, non-controlling stake in them.
According to the report, International Business Machines (IBM) received the largest award, roughly $1 billion, and its shares rose around 12% on the news. This funding is said to back Anderon, a new IBM-founded company building a 300-millimeter quantum wafer foundry in Albany, New York. The report also noted that IBM is matching the grant with its own $1 billion investment.
In addition to IBM, GlobalFoundries got $375 million, while D-Wave, Rigetti, and Infleqtion each got $100 million each. Two other companies, including PsiQuantum and a startup Diraq, also got a $100 million grant.
The news was taken positively by the investors as the stocks that received the grant rose significantly following the announcement. CNBC noted that this grant comes from the 2022 CHIPS and Science Act, though the deals still need to be finalized. While the Commerce Department didn’t give a public reply, IBM framed the initiative as critical to US competitiveness. It said quantum computing could generate up to $850 billion in economic value by 2040 while strengthening national security.
Against this backdrop, lets take a look at some of the best quantum computing stocks to buy and hold.
