Quantum computing stocks have erupted in recent months, with several names doubling or even tripling in value as speculative momentum grips the market. The rally isn't tied to a single catalyst but fueled by surging investor enthusiasm, short-covering, and a growing belief that the industry is nearing its commercial breakthrough.
The current outlook for quantum computing stocks is undeniably interesting. D-Wave Quantum stock (NYSE: QBTS), for instance, has increased by over 200% this year, drawing substantial interest from retail investors.
It's been a wild 24 hours for the stock prices of America's “big four” publicly traded quantum computing companies, which include D-Wave, IonQ, Quantum Computing Inc., and Rigetti.
IonQ, Rigetti Computing and D-Wave Quantum are all in talks about granting shares to the Commerce Department, according to The Wall Street Journal.
Arqit Quantum Inc. offers quantum-safe cybersecurity solutions, positioning itself in a less crowded, high-potential niche compared to quantum computing startups. ARQQ's revenue is growing rapidly, with contracts expected to drive over 100% revenue growth in FY2026 and a strengthened cash position. ARQQ stock has soared over 600% in twelve months, yet its market cap remains modest relative to quantum computing peers, reflecting investor optimism.
Recently, all three of Wall Street's major stock indexes climbed to fresh record-closing highs. The primary catalyst fueling these gains is investor optimism tied to game-changing technological advances, such as the evolution of artificial intelligence (AI).
U.S. quantum computing firm D-Wave Quantum has struck a deal with a company called Swiss Quantum Technology (SQT) to bring D-Wave's Advantage2 quantum computer to Europe.
Rigetti Computing has emerged as a leading player in quantum computing, driving significant momentum in its stock and related ETFs. The Defiance Daily Target 2X Long RGTI ETF offers leveraged exposure to RGTI but is highly speculative and amplifies both gains and losses. Recent catalysts for RGTI include major contract wins, private sector sales, and industry validation, fueling a sharp rally in the stock.
Churchill Capital Corp X is merging with Infleqtion, a quantum tech firm already generating revenue from quantum sensing products. CCCX offers a unique investment thesis, combining commercialized sensing products with a long-term roadmap to scalable quantum computing. Infleqtion's valuation is attractive, trading at less than half the multiples of quantum peers, with a fair value estimate of $55 per share.
Shares in America's “Quantum Four” quantum computing companies surged again yesterday. D-Wave, IonQ, Quantum Computing, and Rigetti all saw their stock prices jump by double-digit percentages.
Despite the Friday sell-off, Wall Street's strongest industry themes reasserted themselves Monday. Quantum computing, rare earth, and AI energy stocks led the way.
IONQ, RGTI, and QBTS strengthen liquidity, hit key tech milestones and expand partnerships ahead of Q3 earnings.
