New York, January 8, 2026, 06:15 EST — Premarket
- D-Wave slipped in premarket trade after agreeing to buy Quantum Circuits in a $550 million cash-and-stock deal
- SEC filings laid out a stock-price collar for the equity portion, a key focus for dilution-sensitive traders
- Peers IonQ, Rigetti, Quantum Computing Inc and Arqit also edged lower in early trading
Quantum computing stocks were lower in U.S. premarket trading on Thursday after D-Wave Quantum said it had agreed to buy Quantum Circuits in a $550 million deal, sending its shares down 3.5% to $30.20. IonQ fell 1.9%, Rigetti slipped 0.8%, Quantum Computing Inc dropped 4.0% and Arqit Quantum eased 2.1%.
Traders focused on the dilution math as much as the headline price tag, with the sector prone to sharp swings and fast reversals. An SEC filing showed the stock portion will be priced off a 10-session volume-weighted average price (VWAP), with a $22.30 to $39.03 collar, and the agreement can be terminated if the closing has not occurred by April 6.
D-Wave said it will pay $300 million in stock and $250 million in cash for Quantum Circuits, a privately held developer of error-corrected superconducting “gate-model” systems — the general-purpose approach to quantum computing — alongside D-Wave’s annealing machines, which are used mainly for optimization. Chief executive Alan Baratz called the deal “a pivotal milestone,” while Quantum Circuits co-founder Rob Schoelkopf said, “Fault-tolerant error-corrected quantum computing is within our reach.” Business Wire
The buyer has also been pushing hardware claims meant to make bigger quantum processors easier to build. On Tuesday, D-Wave said it had demonstrated scalable “on-chip cryogenic control” for gate-model qubits, a move it said could cut wiring inside the ultracold systems that keep quantum processors stable; chief development officer Trevor Lanting said useful systems otherwise require “an impractically large amount of wiring.” Business Wire
Most listed quantum specialists pitch qubits — quantum bits that can hold more than one state — as the route to solving certain problems that overwhelm classical computers. This week’s CES conference circuit is also keeping the theme in front of investors, with Quantum Computing Inc listing CES Foundry appearances on Jan. 7-8 in Las Vegas.
But the trade can turn quickly. The technology is hard to scale, the path to recurring revenue is still uneven across the group, and cash-and-stock deals can weigh on shares if investors start to price in more dilution or a longer timeline to commercial payback.
D-Wave told regulators it hosted a press conference on Wednesday and filed a presentation as part of an 8-K disclosure, giving the market another set of slides to parse before the open. The next test comes at its Qubits user conference on Jan. 27-28, where the company has said it will outline its product roadmap.
