New Nuclear Ventures Aim to Meet Soaring Electricity Demand Amid AI Boom
Nuclear startups, including Aalo and Valar Atomics, are racing to develop small reactors to meet increasing electricity demands driven by AI. In 2025, over $4 billion has been invested in U.S. nuclear ventures, a significant rise from $500 million in 2020. Aalo has raised $136 million, while Valar broke ground on its first reactor in Utah. The nuclear sector sees renewed support and potential for resurgence, with analysts predicting a doubling of data center energy needs by 2030, creating opportunities for nuclear to fill gaps left by other energy sources.
Nuclear startups are rapidly advancing to meet surging electricity demands, particularly from AI-driven data centers. In 2025, investments in U.S. nuclear ventures exceeded $4 billion, a stark increase from $500 million in 2020.
AI-curated by TheiaAalo, led by Loszak, plans to establish a Gigafactory to produce reactors by 2027, while Valar Atomics recently broke ground on its first reactor in Utah. Analysts forecast that data centers may require double their current power usage by 2030, creating a significant opportunity for nuclear energy.
Increased regulatory support under the Trump administration is further fostering this resurgence, with tax credits for new nuclear designs and expedited approvals. Other startups like Kairos Power and Oklo are also making strides, with plans to deploy innovative reactor technologies to meet future energy needs.
