Who's actually funding fusion — and who's getting rich

Fusion has pulled in $7.1 billion so far, but the money isn't spread thin. A small group of companies is eating most of it — and the list of those who've cleared $100 million is shorter than most people think.

The big names on the list are backed by OpenAI, Sam Altman's Founders Fund, and a handful of other well-known Silicon Valley investors. That's the usual crowd: tech billionaires betting on the next energy revolution. The rest of the 40-plus fusion startups are split among smaller rounds, and most haven't reached $100 million yet.

This isn't a story about the future of clean energy — it's a story about capital concentration. A few funds and a few founders are controlling the narrative, the patents, and the headlines. The actual promise — a cleaner grid, cheaper power, energy independence — sits behind a wall of private equity.

Why this matters for us: fusion won't be a public utility we all share; it'll be a private asset owned by a handful of investors, and the benefits won't trickle down to working people unless we push for open access and public oversight from the start.
