Fusion funding hits a record $4.48B in a year — up 69%, total now $14.24B

The Fusion Industry Association's Global Fusion Industry in 2026 report counts $4.48B raised by 56 fusion companies in the 12 months to July — the highest annual total since the survey began in 2021 and 69% above 2025. Cumulative private funding stands at $14.24B, a seven-fold increase since 2021, with the sector employing more than 16,000 people. The survey covers 56 companies (up from 23 in 2021), six of them new entrants this year; 28 are US-based, including all five companies that have raised over $1B.

Why it matters

The 69% jump is the aggregate behind the individual data points this newsroom has been logging — Proxima's €411M record European round, General Fusion's SPAC, Thea's $100M — and it lands the same week fusion got its first public stock ticker (General Fusion's GFUZ). The concentration detail matters most for investors: five companies hold the billion-dollar club, all American, meaning the field-wide number is really a bet on a handful of reactor designs reaching net energy first.

What to watch

Whether the funding pace survives a year without a headline physics result, and which of the six new entrants attract follow-on capital.
