What happened

Fusion startups have raised a total of $7.1 billion to date. The majority of the capital has gone to a small number of companies in the sector.

Why it matters

Capital concentration in deeptech hardware indicates that investors are placing massive bets on a few category leaders rather than spreading risk across early-stage experiments. The long deployment timelines of fusion require sustained follow-on capacity from sovereign and institutional capital.

What to watch

Milestone progress toward commercial net energy gain and private-public co-funding structures.
