Quantum Pure Plays Drop 41–65% as Infrastructure Players Wait

Rigetti Computing reported third-quarter revenue of $1.4 million, a 28% decline that missed analyst estimates by 60%, while pure-play quantum stocks lost between 41% and 65% of their value over the year ending November 10, 2026. The earnings season has clarified an awkward split. Quantum hardware is advancing; the business models behind it are not.

The four listed pure plays — IonQ, Rigetti, D-Wave Quantum and Quantum Computing Inc. — fell between 41.05% and 64.54% over one year, according to data from The Information Network. Quantum Computing Inc. sits 98.63% below its historical peak, though that figure may reflect corporate-action adjustments rather than a clean one-year return.

Nvidia CEO Jensen Huang said in January 2025 that highly useful quantum computers might be roughly 20 years away. His comment triggered a selloff at the time. It also framed the question the current results answer: the classical infrastructure around quantum can pay off long before broad quantum usefulness arrives.

What did the pure plays actually report?

Rigetti posted a $33.2 million operating loss, about 23.7 times quarterly sales. Its $3.1 million GAAP net loss reflected nonoperating accounting effects, not an improvement in the underlying business. Management guided to roughly $20 million in full-year revenue, contingent on acceptance of a system supplied to India's Centre for Development of Advanced Computing — about 11.5% below the $22.6 million analyst expectation.

D-Wave reported $4.5 million in revenue, up 21% year over year, with nine-month bookings of $37.4 million, up 611%. The detail matters: third-quarter bookings fell 19% year over year to $1.9 million. Operating expenses of $55.9 million ran more than twelve times revenue, and adjusted EBITDA loss reached $37.7 million. The company holds about $503 million in cash and securities.

IonQ reported $173.8 million in revenue, up 336% — but $83.5 million, roughly 48%, came from its acquired SkyWater foundry business. Adjusted EBITDA loss was $133.6 million, with about $1.7 billion in cash and investments at September 30, lifted to roughly $3.7 billion pro forma by a subsequent equity offering.

Quantum Computing Inc. grew revenue to $9.5 million from $384,000, mostly through its acquisitions of Luminar Semiconductor, NuCrypt and NHanced Semiconductors. Gross profit was $428,000 — a 4.5% gross margin — against $29 million in operating expenses. It reported a $39.1 million backlog and about $1.3 billion in cash.

Where does the technical progress stand?

Rigetti reported 99.5% median two-qubit gate fidelity on a 108-qubit system and ended September with approximately $497 million in cash. The milestone is real. So is the gap between demonstration and durable commercial economics.

Why do IBM, Intel and Nvidia look better positioned?

IBM announced an operational Quantum System Two at the University of Chicago's Hyde Park Labs on November 6, integrating processors, control electronics, cryogenics and classical computing. Its roadmap targets a fault-tolerant system in 2029 with 200 logical qubits and 100 million quantum gates — a plan, not a proven outcome, and IBM discloses no quantum-specific revenue.

Intel's proposed acquisition of Classiq adds quantum software to its silicon spin-qubit work; quantum remains an option, not a remedy for foundry economics. Nvidia's CUDA-Q and NVQLink link quantum processors to accelerated computing for simulation, calibration and error correction, so the company profits whichever architecture wins.

The division of labor now looks set: processor developers need packaging, software, control systems and classical computing, and the diversified suppliers of those inputs can capture value without betting on any single qubit design. Whether that value becomes material revenue for the incumbents — or the pure plays reach self-sustaining economics first — will show up in gross margins and recognized revenue, not in qubit counts.
