QBTS Exits Q3 With Big Catalysts — But Is the Quantum Hype Priced In?

D-Wave Quantum (QBTS) closed out its third quarter with a string of announcements that, on paper, look like a quantum computing company hitting its stride. The headline number: bookings grew 1,120% year over year, a staggering jump that suggests customers are finally moving from pilots to purchase orders. The company also secured $100 million in CHIPS Act funding, a stamp of approval from the U.S. government that carries both cash and credibility.

The AT&T partnership expanded during the quarter, with the two companies demonstrating a practical application: reducing network optimization time from one hour to just 15 seconds. That's not a lab experiment — it's a real-world use case that gives D-Wave a reference customer in a massive industry. On top of that, D-Wave published research in Nature, a peer-reviewed journal, which lends scientific weight to its annealing-based approach at a time when the quantum sector is crowded with hype.

But the market's reaction has been brutal. QBTS stock is down 55.3% over the past year, and Zacks currently rates it a #4 (Sell). The disconnect between operational progress and stock performance is the central tension here. Investors are clearly asking whether the company's commercial traction can ever justify its valuation, or whether the quantum trade has simply run out of momentum.

It's worth noting that the broader quantum computing sector has been volatile. IonQ (IONQ) has held up better, while Rigetti (RGTI) trades in a similar speculative bucket. D-Wave's quarter, then, is less about whether the technology works — the AT&T demo suggests it does — and more about whether the business can scale fast enough to satisfy a market that has already priced in a lot of future success.

The single most important number in D-Wave's quarter isn't the 1,120% booking growth — it's the 81.42x forward price-to-sales ratio. For context, the industry average is around 4.40x. That means investors are paying roughly 18 times the sector multiple for D-Wave's future revenue. Even if bookings keep growing at triple-digit rates, it will take years of flawless execution to grow into that valuation.

This matters because quantum computing is still a pre-revenue-at-scale industry. D-Wave's bookings are impressive in percentage terms, but the absolute dollar amounts remain small relative to its market cap. The $100 million in CHIPS funding helps extend the runway, but it's not recurring revenue — it's a one-time grant that buys time, not a business model. The AT&T partnership is promising, but telecom network optimization is a niche application; it doesn't yet prove D-Wave can win across logistics, finance, or drug discovery.

The stock's 55% decline over the past year tells you the market has already started repricing quantum names. Investors who bought the hype in 2023 and 2024 are now demanding evidence of commercial scale. D-Wave's Q3 provides evidence of progress, but not proof of a sustainable business. Until bookings convert into recognized revenue and gross margins stabilize, the stock will likely remain a high-beta bet on sentiment rather than fundamentals.

For the broader sector, D-Wave's mixed quarter is a cautionary tale. IonQ's recent moves — the SkyWater acquisition and raised 2026 guidance — show that some quantum players are consolidating and setting clearer revenue targets. D-Wave, by contrast, is still in the "promising but unproven" phase. That distinction matters for investors deciding where to place their quantum bets.
