Oklo Frees Up with Altman's Departure as Board Chair
Company - People | Apr 22, 2025 | EIN

Sam Altman, head of OpenAI, is stepping down as chairman of Oklo, a nuclear startup, after facilitating its public entry via a merger with his special purpose acquisition company, AltC Acquisition Corp., in May 2024. This move is intended to allow Oklo, which specializes in advanced nuclear reactors, the freedom to engage more deeply with AI companies, including potentially OpenAI. Oklo’s Aurora reactors are noted for their simple and scalable designs, providing 75 to 100 megawatts of power, and the company recently signed a deal to provide significant power to data center company Switch. However, it is still in pursuit of contracts with major cloud infrastructure companies, known as hyperscalers, who have shown interest in their emissions-free power. Oklo aims to launch its primary reactor at Idaho National Laboratory before the decade ends. Following Altman’s announcement, Oklo’s stock fell by 12%. Caroline Cochran, Oklo’s co-founder and COO, emphasized continuing strategic partnerships to support AI deployment. Meanwhile, CNBC highlights its upcoming Pro LIVE event aimed at financial professionals, emphasizing networking opportunities to navigate uncertain markets.
