D-Wave's $4.5B valuation looks stretched: bearish case sees stock worth just $850M by 2031

D-Wave Quantum (NASDAQ: QBTS) has a real business, but its valuation of nearly $4.5 billion assumes far faster growth than its sales suggest. Revenue was $3.1 million last quarter, flat year over year. The company's backlog stands at $40.7 million, including a $20 million system sale booked in the first quarter. It lost $48 million in the second quarter and ended June with $546.2 million in cash and securities. D-Wave's quantum annealing technology suits optimisation tasks such as scheduling and routing. It is now pursuing gate-based systems after acquiring Quantum Circuits. A bullish case of 50% annual sales growth would lift 2031 revenue to about $323 million. A bearish case of 15% growth would yield about $85 million; at 10 times sales, D-Wave would be worth only $850 million.

The company expects most of its 2026 revenue in the fourth quarter, when it plans to ship two annealing quantum computer systems. D-Wave prices each at $20 million to $40 million, while its revenue for the twelve months to June 30, 2026 was $12.4 million, down 44.2%. Cloud customers are moving into production. Production applications made up over 37% of first-half cloud subscription revenue, against 9.8% a year earlier, and second-quarter subscription revenue rose 50% to $1.9 million. D-Wave held $546 million in cash and short-term investments against $48.1 million of debt. It burned $120 million over the twelve months, leaving about 4.5 years of cash.

D-Wave Quantum faces securities class action; lead plaintiff deadline December 14, 2026

Investors in D-Wave Quantum (NASDAQ: QBTS) have until December 14, 2026 to seek lead plaintiff status in a federal securities class action against the company. The suit covers those who bought the company's securities between February 26, 2026 and August 25, 2026. The complaint alleges D-Wave and its executives overstated the company's business and financial prospects, making public statements that were false or misleading. On August 6, D-Wave reported second-quarter revenue of $3.08 million, down from $3.1 million a year earlier and below analyst estimates of $4.03 million to $4.08 million. The stock fell 9.28% to $19.41. On August 25, the company said chief financial officer John Markovich was retiring effective September 2. The shares fell 9.51% to $17.51 the next day.

D-Wave's flat $3.1M quarterly revenue clashes with its $5.4B valuation as system sales lag

D-Wave Quantum (QBTS) reported second-quarter 2026 revenue of $3.1 million, essentially flat on a year earlier. The stock carries a $5.4 billion valuation, or 434.9 times sales. Systems revenue was only about $300,000, as each annealing system, priced at $20 million to $40 million, takes time to site, build, install, and calibrate. Cloud subscriptions rose 50% and professional services climbed more than 18%. Adjusted EBITDA loss widened 85%, and gross margin fell to 55.4% from 63.8%. Backlog reached $40.7 million on June 30, up 668%, and management expects about 57% of it to become revenue within twelve months. It plans to ship two systems in 2026, probably in the fourth quarter. D-Wave held $546.2 million in cash and marketable securities at the end of June.
