The technology riding high on a surge of record orders and deep-pocketed federal backing is also fighting a rear-guard action to defend its core scientific thesis. D-Wave Quantum finds itself in the unusual position of touting a near-2,000% leap in bookings while simultaneously refuting a challenge to the very principle of quantum supremacy that underpins much of its valuation.
Over the past week, the company’s technical credibility came under fire from researchers at the Flatiron Institute, who published a study suggesting that classical simulation algorithms could match the performance of D-Wave’s quantum processors. D-Wave hit back sharply, arguing that the algorithms tested had failed on the most complex three-dimensional spin-glass problems involving cubic and diamond lattices. The company stood by its “beyond-classical” benchmarks, pointing to peer-reviewed results published in the journal Science. For a sector where sentiment can shift on a single piece of analysis, the rebuttal helped steady the stock after an intraweek wobble.
That stock has been on a tear despite the turbulence. D-Wave shares closed at €23.75 on Wednesday, good for a 54% monthly gain, though still 38% below the 52-week high of €38.48. The 30-day annualised volatility has clocked in at 133%, a figure that confirms the equity inhabits the most speculative corner of the growth-stock universe. The market capitalisation hovers around $10.3 billion — a multiple that relies almost entirely on the eventual conversion of a towering order backlog.
Should investors sell immediately? Or is it worth buying D-Wave Quantum?
The scale of that backlog was laid bare in the first quarter of 2026, which delivered a dramatic split screen. Bookings hit a record $33.4 million, up roughly 2,000% from the year-earlier period. But realised revenue came in at just $2.86 million, missing the consensus estimate of $4.14 million and falling 81% year over year. The drop was largely distortion from a one-time system sale in the prior-year period. On the bottom line, D-Wave beat expectations with a per-share loss of $0.05 versus the $0.08 forecast, providing a sliver of operational comfort.
Away from the numbers, the company continues to benefit from the U.S. government’s push to secure domestic leadership in advanced microelectronics. D-Wave secured second-year funding for its SQFab project — “Improved Materials for Superconducting Qubits with Scalable Fabrication” — through the Northeast Regional Defense Technology Hub, part of the $25 million Microelectronics Commons programme awarded across four projects. More substantially, the company signed a non-binding letter of intent with the U.S. Department of Commerce for roughly $100 million under the CHIPS and Science Act, in exchange for an equity stake. The capital is earmarked for developing a 100,000-qubit annealing system and a 10,000-qubit gate-model machine.
Investors will have a chance to gauge the commercial trajectory when D-Wave presents at the TD Cowen Sustainability & Industrial Innovation Conference today, but the next major milestone is already on the calendar. On June 18, the company will host Qubits Europe 2026 in London, where it plans to demonstrate practical use cases on its dual-platform architecture across logistics, artificial intelligence and materials science. For a stock priced almost entirely on future expectations rather than present revenue, tangible proof that the record bookings can become recurring revenue will carry far more weight than any quarterly number. The scientific row may fade, but the conversion challenge remains the harder test.
