NextFin News - OpenAI is in advanced negotiations to secure a massive, multi-decade supply of electricity from Helion Energy, the fusion startup backed by U.S. President Trump’s prominent tech ally and OpenAI CEO Sam Altman. According to a person familiar with the situation, the framework of the deal involves OpenAI receiving an initial 12.5% of Helion’s production, with the ambition of securing 5 gigawatts of power by 2030. The scale of the agreement is staggering, reportedly aiming for 50 gigawatts by 2035—a volume of energy that would dwarf the current consumption of entire mid-sized nations and signal a radical bet on the commercial viability of nuclear fusion.
The timing of the talks coincides with a period of unprecedented energy anxiety within the artificial intelligence sector. As OpenAI scales its compute clusters to train next-generation models, the traditional power grid has become a primary bottleneck. By moving toward a direct purchase agreement with Helion, OpenAI is attempting to bypass the constraints of aging infrastructure and the rising costs of fossil-fuel-based electricity. The deal also highlights the complex web of interests surrounding Altman, who led Helion’s $500 million Series E round in 2021 and remains a significant shareholder. To mitigate conflict-of-interest concerns, Altman has reportedly stepped down as Helion’s board chair and recused himself from the formal negotiations between the two companies.
Helion’s technological progress has provided the necessary momentum for these discussions. In February 2026, the company’s Polaris prototype achieved plasma temperatures of 150 million degrees Celsius—ten times hotter than the sun’s core—and became the first private venture to demonstrate measurable deuterium-tritium fusion. While Helion’s ultimate goal is to use a deuterium-helium-3 fuel mix for more efficient direct electricity conversion, the recent milestones suggest the company is nearing "scientific breakeven," the point where a reactor produces more energy than it consumes. No private entity has yet reached this threshold, making OpenAI’s 50-gigawatt target a high-stakes gamble on a technology that has remained "thirty years away" for the better part of a century.
The competitive landscape for clean energy in Silicon Valley is rapidly intensifying. Google has already secured agreements with Commonwealth Fusion Systems, including a 200-megawatt power purchase deal, while Microsoft signed a 50-megawatt contract with Helion back in 2023. OpenAI’s proposed 5-gigawatt starting point represents a ten-fold increase in ambition compared to its peers, reflecting the company’s belief that the future of AI is inextricably linked to the mastery of abundant, carbon-free energy. If Helion can deliver on its 2028 goal of providing power to the grid in Washington State, OpenAI will have secured a first-mover advantage in the most important commodity market of the 21st century.
However, the path to 50 gigawatts is fraught with regulatory and engineering hurdles. Beyond the physics of fusion, Helion must still finalize site selections and navigate a complex permitting environment that has historically slowed nuclear projects. The "basic framework" currently under discussion remains conditional on Helion hitting specific performance benchmarks. For OpenAI, the risk of failure is balanced by the existential necessity of power; without a breakthrough in energy generation, the exponential growth of AI intelligence may eventually collide with the physical limits of the Earth's power capacity. The deal is less a standard procurement contract and more a strategic alliance intended to ensure that the lights stay on as the models get smarter.
