Billionaires Have Chosen Their Favorite Quantum Computing Stock, and It's Not IonQ, Rigetti Computing, or D-Wave Quantum - Yahoo Finance

Billionaires are heavily investing in IBM as their top quantum computing stock, bypassing pure-play firms like IonQ, Rigetti, and D-Wave, according to 2026 filings. IBM’s hybrid quantum-classical approach and established enterprise infrastructure give it an edge over niche competitors, attracting high-net-worth investors seeking long-term stability. Analysts compare quantum computing’s potential to AI’s rise, with Defiance ETF executives calling it the "next big play" for tech portfolios post-2025. Unlike speculative startups, IBM’s diversified revenue streams—cloud, AI, and quantum—reduce risk while offering exposure to quantum’s growth through its Qiskit platform. The shift signals a preference for integrated tech giants over volatile pure-play quantum stocks, reflecting broader market caution amid quantum’s prolonged commercialization timeline.
