In a period of five days in late September and early October 2025, shares of popular quantum computing firm D-Wave Quantum Inc. (NYSE: QBTS) spiked by nearly 22%, capping off a stellar month in which the stock more than doubled. While QBTS shares stand out across the broader market, quantum rivals like Rigetti Computing (NASDAQ: RGTI) performed even better during those periods. D-Wave's latest gains are largely attributable to two factors: a suggestion to investors that the company's annealing quantum tech has broad marketability and sector-wide momentum driven by encouraging news posted by others in the space.
For many investors, the industry-wide gains of recent weeks may signal that it's time to invest in a quantum tech-focused exchange-traded fund (ETF) to capture a wide swath of the gains in this sphere. But for those primarily focused on individual names, the question becomes whether D-Wave will continue to stand out and if its torrid growth will continue despite significant overvaluation risk.
