Why Is D-WAVE QUANTUM INC (QBTS) Stock Down Today?

QBTS stock fell 8.39% to $18.68 in morning trading, driven by a recent earnings miss and broader weakness in the quantum computing sector. The company reported second-quarter results that fell short of expectations, with revenue and earnings below estimates. This decline occurred amid a broader sell-off in quantum computing stocks, including IonQ and Rigetti, as investors reassessed the sector's growth potential.

What Happened

D-Wave Quantum reported Q2 earnings per share of $(0.13), missing the estimated $(0.10), and revenue of $3.076 million, which was below the expected $4.025 million. This performance followed a Q2 earnings report that had already signaled challenges, with the stock dropping after the results were released. The company also faces the broader issue of declining revenue year over year, with a 44.2% drop in trailing twelve-month revenue. Despite a growing order book, the company's struggles to convert that into revenue have raised concerns among investors.

The recent earnings report coincided with a broader downturn in quantum computing stocks. IonQ and Rigetti also saw significant declines, suggesting a sector-wide reassessment of growth expectations. Additionally, insiders have been selling shares, with eight transactions totaling $35.4 million in the last 90 days. The most recent sale occurred on July 21, 2026, further signaling caution from company executives.

What The Data Shows

The stock has declined 11.9% over the last eight sessions, moving from $21.21 to $18.68. Over the past 52 weeks, it has traded between $12.75 and $46.75, with 35 fresh 52-week lows recorded on August 25. Unusual options activity in the last 36 hours included a notable call option print of $137,000, with no put activity. The stock's beta of 2.16 indicates it is more volatile than the broader market.

What To Watch

The company is not scheduled to report earnings in the near term. Investors should monitor the breadth of sector coverage and whether quantum computing stocks stabilize or continue their downward trend.
