The U.S. government will acquire minority equity stakes in D-Wave Quantum, Rigetti Computing, and Quantinuum through a combined $300 million CHIPS Act funding deal administered by the Department of Commerce. Each company will receive $100 million structured as research-and-development grants aimed at scaling domestic quantum-computing hardware and semiconductor supply chains. The announcement sent shares of all three firms higher in premarket trading Tuesday, with Quantinuum rising 3.9% to $51.56, D-Wave up 5.4% to $17.48, and Rigetti gaining 7.4% to $16.33.

Rigetti plans to deploy funds to address technical bottlenecks in scaling superconducting quantum processors, expand cryogenic capacity, and accelerate manufacturing at specialized facilities. British Columbia-based D-Wave will advance microelectronics R&D for prototyping advanced semiconductor technology and scalable high-performance quantum hardware. Quantinuum will focus on building scalable, reliable integrated photonics engines through domestic partnerships, collaborating with Global Foundries to fabricate next-generation ion traps and with Monarch Quantum to manufacture integrated lasers and optical components.
