D-Wave Quantum Slips 8.2% as Valuation Doubts, Lawsuit and Tech-Wide Retreat Converge
Published on 10/17/2026 at 14:51 | Editorial boerse-global.de
D-Wave Quantum shares came under heavy selling pressure on Friday, closing at EUR 10.49 for a loss of 8.2% as a broad retreat from growth-oriented technology names compounded company-specific worries. The decline left the quantum computing specialist just 3.6% above its 52-week low of EUR 10.13.
The downdraft was not tied to any single corporate announcement. Instead, it reflected a wider pullback across the tech sector: the Nasdaq closed 2.1% lower, and 68 of the 75 technology constituents in the S&P 500 finished in the red, according to AP. Market watchers pinned the caution on doubts over the sustainability of heavy spending on artificial intelligence infrastructure, with rising government bond yields adding further pressure on capital-intensive growth companies.
Legal Headwinds and Insider Share Withholding
Beyond the sector-wide gloom, D-Wave faced its own set of distractions. A securities class action was filed against the company and certain executives on Thursday, alleging that management overstated the business and financial prospects of the quantum computing group. The claims remain unproven.
Separately, mandatory filings with the US Securities and Exchange Commission disclosed changes in executive shareholdings. CEO Alan E. Baratz had 52,320 shares withheld on Thursday, while Acting CFO Gregory Golkov saw 15,859 shares withheld. Both transactions were tax-withholding arrangements triggered by the vesting of restricted stock units, not discretionary sales.
Should investors sell immediately? Or is it worth buying D-Wave Quantum?
Delivery Milestone in Como
On the operational front, D-Wave completed a tangible European milestone. Its Advantage2 quantum computer, a system boasting more than 4,400 qubits, arrived for installation at Villa Saporiti in Como, in Italy's Lombardy region — the company's first commercial annealing quantum machine in the country.
The deployment is funded by Swiss Quantum Technology SA under a EUR 10 million agreement. As part of that contract, the Swiss firm secured 50% of the system's computing capacity over a five-year term and holds an option to acquire the machine outright.
SkyWater Partnership Extended
D-Wave also extended its manufacturing partnership with SkyWater Technology, continuing the production of superconducting quantum chips at SkyWater's facility in the US state of Minnesota under a multi-year agreement. Contractual clauses safeguard D-Wave's intellectual property; the parties did not disclose financial terms.
The collaboration has already produced a pilot project on maintenance scheduling. According to the company, the trial cut process-related delays at the fab by up to 30%.
None of it was enough to steady the stock before the weekend. With valuation questions lingering over a company still posting operating losses, the technical wins and the Como installation faded into the background as investors focused on the broader tech selloff and the newly filed lawsuit.
