Overview
A Sam Altman-backed fusion energy company that signed the world's first fusion power purchase agreement, committing to supply Microsoft with 50+ megawatts from its Orion power plant by 2028. Helion raised $465 million in June 2026 (bringing total funding to over $1.5 billion) at a $15.5 billion valuation and broke ground on Orion in Chelan County, Washington, chosen for its transmission access and energy-innovation legacy.

Strategic Risks
- Commercial fusion power remains unproven at grid scale; Orion is Helion's first-ever power plant
- 2028 delivery timeline for the Microsoft PPA leaves limited margin for technical delays
Future Outlook
- Orion plant construction and eventual grid connection expected to be the key proof point for Helion's fusion approach
- Success or failure of the Microsoft PPA is likely to set the tone for hyperscaler appetite for fusion power deals more broadly
- Chelan County Conditional Use Permit clears the way for fusion generator building construction to proceed
