1,900% Stock Gains and Hate Mail: Welcome to Quantum Investing - Bloomberg.com

Quantum computing stocks surged up to 1,900% in 2025, attracting aggressive retail investors despite warnings from analysts about volatile, speculative markets. Early-stage quantum firms—many pre-revenue—drew billions in capital as traders bet on breakthroughs in cryptography, drug discovery, and AI acceleration. Critics argue the sector’s hype outpaces reality, with most companies years from commercial viability, sparking backlash against promoters and financial influencers. Hedge funds and institutional investors now clash with retail traders over quantum’s long-term potential, fueling market turbulence and regulatory scrutiny. The boom has triggered ethical debates over misleading claims, as some firms face lawsuits for overstating quantum capabilities amid the frenzy.
