D-Wave Quantum announced it has entered into a definitive agreement to acquire Quantum Circuits Inc. in a transaction valued at $550 million. The consideration consists of $300 million in newly issued D-Wave shares and $250 million in cash. D-Wave plans to integrate Quantum Circuits’ error-corrected gate-model technology into its product lineup and target the launch of superconducting gate-model systems by 2026. The deal is subject to regulatory clearance and is expected to close in late January 2026, bolstering D-Wave’s capabilities across both annealing and gate-model architectures.

On December 5, 2025, D-Wave director John D. DiLullo sold 8,000 directly held shares for a total transaction value of $218,890, reducing his direct stake from 35,803 to 27,803 shares. This sale represented 22.3% of his direct holdings and follows a period in which the company’s stock appreciated 567.52% over the prior 12 months. DiLullo’s recent sales have consistently involved 8,000-share disposals, and he retains approximately 27.6% of his original direct position, suggesting a measured approach to profit-taking rather than a complete exit.

D-Wave achieved an industry first by demonstrating scalable on-chip cryogenic control of gate-model qubits, leveraging multiplexed digital-to-analog converters originally developed for its annealing systems. The multichip package integrates high-coherence fluxonium qubit chips with a multilayer control chip fabricated in partnership with NASA’s Jet Propulsion Laboratory. This breakthrough reduces wiring complexity—controlling tens of thousands of qubits with just 200 bias lines—while preserving qubit fidelity, positioning D-Wave to deliver the first commercially viable gate-model quantum computers with a smaller footprint and lower cryogenic overhead.

In 2025, D-Wave shares gained 211%, driven by growing adoption of its quantum annealing services and strategic government deployments. Recurring revenue from the Leap cloud platform remained a pillar of stability, alongside periodic hardware sales of its Advantage2 system, which features a 4,400-qubit QPU capable of solving complex optimization tasks thousands of times faster than its predecessor. Analysts forecast net sales rising from $8.83 million in 2024 to $39.83 million in 2026 and $78.28 million in 2027. With over 200 million problem submissions to date and a global client base spanning manufacturing, logistics and life sciences, D-Wave is positioned for continued momentum as it expands both its annealing and gate-model offerings.
