Quantum computing stocks are experiencing extreme volatility as speculative investors pour into companies such as Rigetti, IonQ, D-Wave Quantum, and Quantum Computing Inc. Shares of these so-called “Quantum 4” firms have jumped over 100% this year, despite limited revenue and persistent losses.
Rigetti’s meteoric rise — from $1 to $58 per share before settling around $36 — illustrates the frenzy. The company now trades at more than 1,000 times its annual sales, dwarfing even high-profile AI names like Nvidia. “Valuing these companies is more art than science,” said Benchmark analyst David Williams, who still rates Rigetti a “buy.”
Analysts say excitement is fueled by the potential for quantum computers to revolutionize industries from finance to medicine. JPMorgan and HSBC recently unveiled quantum-based financial systems, while the U.S. government is reportedly considering funding initiatives in the sector. McKinsey estimates the global quantum computing market could reach $100 billion, though experts caution that commercial breakthroughs remain years away.
“It’s the holy grail of computing,” said Neuberger Berman’s Rick Bradt. “But investors are trying to price in a future that hasn’t arrived yet.”
