Source Summary
Global private investment in nuclear fusion reached $4.48 billion in 2025, a 69% increase from the previous year, marking a shift from laboratory research to commercial deployment. Major energy companies including Italian firm Eni are moving beyond startup backing to plan their own commercial fusion plants, with Eni targeting deployment in Europe by the early 2040s or sooner.
Why it matters
The record funding and major energy companies' direct involvement signal that nuclear fusion is transitioning from speculative research to a technology expected to contribute to the commercial energy grid.
