Helion Energy, the Seattle‑area startup developing pulsed‑magneto‑inertial fusion reactors, is in advanced talks to supply OpenAI with up to 5 gigawatts of electricity by 2030, with a roadmap that could expand the commitment to 50 GW by 2035. The negotiations, first reported by Axios and corroborated by Bloomberg and GeekWire, would make Helion the first commercial fusion provider to power a major AI operation at scale.
OpenAI’s demand for power has exploded as its models grow larger and training cycles lengthen. The company already sources renewable electricity for its data centres, but the projected compute load for next‑generation systems would outstrip the capacity of conventional grids in many regions. Securing gigawatt‑scale fusion power would give OpenAI a predictable, low‑carbon supply and could lower the marginal cost of training runs that currently depend on spot‑market electricity prices.
The deal matters beyond the two firms. It signals that fusion technology is moving from laboratory proof‑of‑concept toward real‑world commercial contracts, a milestone that could unlock further private investment and accelerate regulatory pathways. For the AI sector, it underscores a growing willingness to lock in long‑term energy sources to sustain the “compute arms race” while addressing climate concerns.
Watch for a formal announcement of the contract terms in the coming weeks, as well as Helion’s timeline for its first commercial plant, slated for early‑mid‑2020s. Equally important will be any joint research initiatives on AI‑driven plasma control, which could improve reactor efficiency and create a feedback loop between the two cutting‑edge fields. The outcome will shape both the economics of large‑scale AI and the commercial trajectory of fusion power.
