What the current evidence supports

Human editorial judgment · 2026-06-28

Too early to adopt

Why
Real measured milestones (150M C, Sandia-confirmed >13 keV D-T fusion, first private D-T/tritium regulatory approval) but the headline electricity-generation claim is unmet, the company has a documented history of missed deadlines, and credentialed experts publicly doubt the 2028 Microsoft commitment; a smaller fallback testbed signals unresolved physics.
Next
Watch for an independently corroborated net-electricity announcement from Polaris and progress on the Orion/Microsoft 2028 50 MWe obligation; treat the 2028 PPA (with financial penalties) as the falsifiable checkpoint.
