New York, Jan 8, 2026, 15:12 (EST) — Regular session
- D-Wave Quantum shares fell in afternoon trading as investors weighed a $550 million acquisition and its cash-and-stock mix.
- The company says the deal expands its push into “gate-model” quantum systems, a more general approach than see-it-now “annealing” machines.
- Traders are looking to the Jan. 27-28 Qubits 2026 conference for the next roadmap update.
D-Wave Quantum Inc shares were down 3.8% at $29.05 on Thursday, a day after the company unveiled a $550 million agreement to buy Quantum Circuits, a private developer of gate-model quantum hardware.
The move matters because D-Wave is trying to prove it can turn quantum computing from demos into sales, and the acquisition is a costly way to speed that pitch. Gate-model systems are designed to run broader classes of quantum algorithms, while D-Wave’s annealing machines are built mainly to tackle optimization problems.
Investors are also fixated on the deal math. D-Wave will pay $250 million in cash and $300 million in stock, and the share portion will be set off a 10-day volume-weighted average price — an average that gives more weight to heavier trading days — with a collar between $22.30 and $39.03 per share, a filing showed.
D-Wave’s chief executive Alan Baratz said the tie-up should accelerate a “dual-platform” strategy that spans both annealing and gate-model systems, while Quantum Circuits chief scientist and co-founder Rob Schoelkopf said fault-tolerant, error-corrected quantum computing was “within our reach.” Quantum Circuits CEO Ray Smets said the deal would speed the push toward commercially viable gate-model machines.

The acquisition follows a separate technical update this week. D-Wave said it had demonstrated scalable, on-chip cryogenic control of gate-model qubits — the basic units of quantum computers — in an effort to cut the amount of wiring needed inside ultra-cold systems.
Elsewhere in the sector, IonQ was up about 2.3% while Quantum Computing Inc added about 1.9%; Rigetti was roughly flat. The mixed tape underlined how stock moves in the group can swing on deal terms and the next claimed milestone, not just the broader market mood.
But there are clear ways this can go wrong. The acquisition still needs U.S. antitrust clearance under the Hart-Scott-Rodino process and approval to list the new shares, and D-Wave’s dilution could shift with its stock price into closing.
What comes next is more concrete. D-Wave has pointed investors to its Qubits 2026 conference on Jan. 27-28 in Boca Raton, Florida, where it plans to lay out its product roadmap — a near-term test of whether the Quantum Circuits deal and this week’s hardware claims change the timeline in a way the market will pay for.
