Helion will supply OpenAI with 5 gigawatts of fusion electricity by 2030 (roughly 100 Helion 50-MW reactors, equivalent to ~73% of Grand Coulee Dam) — a 100x step-up from Helion's existing Microsoft commitment.

Helion will supply OpenAI with 5 gigawatts of fusion electricity by 2030 (roughly 100 Helion 50-MW reactors, equivalent to ~73% of Grand Coulee Dam) — a 100x step-up from Helion's existing Microsoft commitment. | Helion commercial electricity milestone

Key catalyst: Helion commercial electricity milestone

Watch events: OpenAI-Helion definitive agreement; Helion Orion commissioning; site selection

Deal reported March 2026 by Axios; framework conditional on site selection and Helion breakeven. 100 reactors by 2030 requires unprecedented manufacturing scale-up.
