Commonwealth Fusion Systems said it raised $1.8 billion from investors including billionaire Bill Gates and venture capitalist John Doerr in the fusion industry’s largest financing deal.

Tiger Global Management led the Series B funding round, attracting new backers that also included Marc Benioff’s Time Ventures and Emerson Collective, CFS said in a statement Wednesday. The Cambridge, Massachusetts-based company will use the money to build and operate a demonstration system and to begin construction on a commercial fusion reactor that may be complete in the early 2030s.
