Commonwealth Fusion Systems (CFS) is the best-funded fusion power startup, having raised $4 billion from investors over the last seven years, including the $1 billion the company has raised now. But given the progress at CFS (and Kim’s recent arrival, protestations notwithstanding), the startup is likely to go public sooner than that. If CFS goes public in the coming years, it will still have several years of heavy expenditures ahead. One fusion company, General Fusion, went public via a SPAC deal earlier this month, and another, TAE Technologies, will do so by merging with Trump Media and Technology Group. CFS knows this, having already sold half the output of its first power plant to Google.
