D-Wave vs. IonQ Isn’t the Only Quantum Battle — Here’s the Real Race

• D-Wave (QBTS) reported Q4 revenue of $2.75M (missing consensus by 27.6%) with FY2025 revenue of $24.59M, up 179% year-over-year, while Q4 bookings surged to $13.4M sequentially and January 2026 bookings exceeded $30M. IonQ (IONQ) delivered Q4 revenue of $61.89M, beating consensus by 53.7%, with FY2025 revenue of $130.02M (up 202% year-over-year), becoming the first public quantum company to cross $100M in annual GAAP revenue, and issued 2026 guidance of $225M-$245M.

• D-Wave is monetizing near-term optimization solutions for enterprise customers today while expanding into gate-model computing, whereas IonQ is pursuing a full-stack platform strategy by acquiring SkyWater Technology to control its own chip foundry and building national quantum networks globally.

D-Wave Quantum (NYSE:QBTS) and IonQ (NYSE:IONQ) both just reported earnings, revealing two very different bets on how quantum computing reaches commercial scale. D-Wave is selling solutions today. IonQ is building the platform it believes will dominate tomorrow.

D-Wave’s Q4 was soft on headline numbers. Revenue came in at $2.75 million, missing consensus by -27.63%, and full-year 2025 revenue totaled $24.59 million, up 179% year-over-year. The growth is real, but the base is tiny. The bookings story matters more: Q4 bookings hit $13.4 million, up 471% sequentially, and January 2026 alone generated over $30 million in bookings. CEO Alan Baratz put it plainly:

“We are entering 2026 with exceptional momentum: generating over $30 million in Bookings in January alone, expanding our market leadership through the acquisition of gate-model quantum computing company Quantum Circuits, Inc., and securing an eight-figure enterprise QCaaS agreement that underscores growing customer confidence in our technology’s power to transform enterprise operations.”

IonQ’s quarter looked different in scale. Q4 2025 revenue reached $61.89 million, beating consensus by 53.73% and growing 428.5% year-over-year. Full-year 2025 revenue hit $130.02 million, up 202%. IonQ became the first public quantum company to cross $100 million in annual GAAP revenue, separating it from every sector peer.

D-Wave’s thesis is that annealing quantum computers solve real optimization problems now, for real paying customers. The company counts over 135 customers including 70+ commercial enterprises and two dozen Forbes Global 2000 companies. Ford Otosan runs a hybrid-quantum vehicle manufacturing scheduling application in production — not a pilot. D-Wave also acquired Quantum Circuits to add gate-model capability, targeting a 17-qubit system in 2026, scaling to 49 qubits in 2027 and 181 in 2028.

IonQ is playing a larger game. CEO Niccolo de Masi framed it directly: “We have now integrated our capabilities to create powerful operating momentum into 2026.” The company has deployed national quantum networks in Switzerland, Slovakia, and Romania, struck deals with AstraZeneca, NVIDIA, CERN, and South Korea’s KISTI, and is acquiring SkyWater Technology to control its own chip foundry. 2026 guidance calls for $225 million to $245 million in revenue, with the SkyWater deal not yet included.

Both stocks have pulled back hard in 2026. QBTS is down 32.89% year-to-date while IONQ has dropped 26.5% over the same period. Neither is cheap relative to revenue. D-Wave trades at a market cap of roughly 260x its annual revenue. IonQ, despite its scale advantage, still burns cash aggressively, with full-year 2026 adjusted EBITDA losses expected between ($330 million) and ($310 million).

IonQ’s revenue trajectory, customer roster, and platform breadth reflect a company scaling toward commercial infrastructure. D-Wave’s optimization niche, gate-model expansion, and growing bookings reflect a company already generating quantum-derived revenue. Both carry significant dilution risk and pre-profitability losses as the sector matures.

Wall Street is pouring billions into AI, but most investors are buying the wrong stocks. The analyst who first identified NVIDIA as a buy back in 2010 — before its 28,000% run — has just pinpointed 10 new AI companies he believes could deliver outsized returns from here. One dominates a $100 billion equipment market. Another is solving the single biggest bottleneck holding back AI data centers. A third is a pure-play on an optical networking market set to quadruple. Most investors haven’t heard of half these names. Get the free list of all 10 stocks here.
