12:14 PM EDT, 08/28/2025 (MT Newswires) -- Nvidia ( NVDA ) , through its venture capital arm Nventures, has joined existing investor Alphabet's Google ( GOOG ) in financing Commonwealth Fusion Systems and its goal of delivering a functioning fusion power plant.

Commonwealth raised $863 million in an oversubscribed series B2 fundraising, which it will use to complete its fusion demonstration machine in Devens, Massachusetts, and advance development work on its first ARC power plant in Chesterfield County, Virginia, the private fusion company said Thursday.

Commonwealth said it aims to build the world's first grid-scale fusion power plant in the early 2030s, supported by strategic partnerships with Dominion Energy ( D ) and Google ( GOOG ), which has also agreed to buy half the power produced by the plant.

The company's fusion demonstration machine, called SPARC, is around 65% complete and on track to achieve a critical technical milestone in 2027, Bloomberg cited company CEO Bob Mumgaard as saying in a conference call.
