Unverified

Credibly-reported claims — analyst notes, sourcing citing “people familiar with the matter,” deals where the companies involved declined to comment — that haven't been officially confirmed. Kept structurally separate from the sourced evidence above; treat as a lead worth researching further, not an established fact.

Reportedly negotiating a large-scale power supply deal with OpenAI

40% confidence

Helion Energy was reported to be negotiating a deal to supply OpenAI with substantial power from fusion generation -- described as 5 gigawatts by 2030 ramping to 50 gigawatts by 2035 -- according to a source familiar with the talks.

Reported by Axios (via GeekWire) citing an unnamed source familiar with the talks; neither Helion nor OpenAI has confirmed definitive contract terms at this scale, and Helion has not yet demonstrated grid-scale fusion power generation.
