Quantum Computing Inc. (QUBT): 2025’s Wild 3,200% Quantum Stock Surge – Boom or Bubble?

QUBT’s share price has been on a rollercoaster in 2025, reflecting both speculative hype and sudden reversals. After an explosive rally in late 2024, QUBT entered 2025 at lofty levels and promptly cratered: shares plunged about –37% in January 2025 and –42% in February 2025 Portfolioslab, wiping out roughly two-thirds of its value in the first two months. This steep pullback from the late-2024 peak was likely a combination of profit-taking and sober reflection on the minimal fundamentals supporting the price. However, the volatility didn’t end there. QUBT staged another dramatic comeback in Q2 2025: the stock rebounded +68% in May and +69% in June 2025 Portfolioslab amid renewed enthusiasm for quantum tech. Notably, on June 11, 2025, QUBT spiked as much as +38% intraday after Nvidia CEO Jensen Huang publicly hailed quantum computing as nearing “an inflection point” Nasdaq Nasdaq. Huang’s endorsement, coupled with a cooler inflation report, ignited a sector-wide quantum rally that day – with QUBT leading the pack Nasdaq Nasdaq. This exemplifies QUBT’s high beta and sensitivity to macro sentiment: any whiff of positive news can trigger outsized gains, while disappointments or dilutive financing can send it diving.
