Fusion has crossed from physics experiment to capitalised industry — over $14B raised and AI hyperscalers signing offtake — but it remains a pre-revenue, mostly-private call option on engineering milestones still years from net commercial electricity.
📈 What changed: Commonwealth Fusion Systems' SPARC reached ~75% construction complete by April 2026 (up from ~60%), with first plasma now firmly targeted for 2027 rather than late-2026, per CFS c…
| Indicator | Score | Reading |
|---|---|---|
| Maturity higher is better · high confidence | 24/100 | Research/prototype stage; many competing architectures, no commercial plant. |
| Evidence Strength higher is better · high confidence | 75/100 | Underlying physics peer-reviewed; investment claims rest on reputable trade press. |
| Commercial Proximity higher is better · high confidence | 27/100 | Pre-revenue; offtake commitments exist but no power delivered. |
| Capital & Policy Support higher is better · high confidence | 62/100 | Strong capital formation and national programmes; regulation an enabler, not a driver. |
| Crowding Risk lower is better · high confidence | 68/100 | Intense private interest and stretched valuations; limited public positioning. |
| Reflexivity Risk lower is better · medium confidence | 82/100 | Archetypal frontier reflexivity: milestone-driven, celebrity-backed, pre-revenue. |
