Prediction: This quantum computing stock is going to plummet in the second half of 2026 - MSN

Key Points The U.S. government recently announced plans to invest $100 million in Rigetti Computing, which will be spread over the next three years. Rigetti is a leader in the quantum computing industry, but even its best systems still make too many errors to solve complex real-world problems. Rigetti stock is trading at a sky-high valuation, which could result in significant downside in its stock in the second half of 2026. 10 stocks we like better than Rigetti Computing › Last month, the U.S. government announced plans to acquire equity stakes in nine different quantum computing companies, providing $2 billion in total funding to help America build a leadership position in this important industry. Rigetti Computing (NASDAQ: RGTI) will receive a $100 million investment over three years, and its stock has jumped by 20% since the news broke. Quantum computers can use a concept called superposition to simulate multiple solutions to a given problem at once, so they are more efficient at processing specific workloads compared to traditional computers, especially in areas like science and cryptography. Rigetti makes some of the industry's best quantum systems, but they still make far too many errors to solve most real-world problems.
