Leopold Aschenbrenner bets billions on ex-Bitcoin miners’ energy assets for AI compute

Leopold Aschenbrenner, the former OpenAI researcher turned hedge fund manager, has placed one of the most provocative bets in recent market history. His fund, Situational Awareness LP, held $13.67 billion in equity exposure as of March 31, 2026, nearly tripling from $5.52 billion at the end of 2025. The core thesis: former Bitcoin miners sitting on massive energy infrastructure are the real bottleneck play for AI scaling.

The 24-year-old’s top holdings read like a who’s who of companies that once ran warehouses full of ASIC rigs. IREN, Core Scientific, Riot Platforms, and CleanSpark all feature prominently in the portfolio, alongside energy firm Bloom Energy and compute company CoreWeave.

Power over chips

Aschenbrenner’s investing philosophy flips the conventional AI narrative on its head. His fund is betting that chips aren’t actually the scarce resource anymore. The real constraints on scaling AI, in his view, are power and land. Securing grid connections, building substations, getting site permits.

Former Bitcoin miners happen to own exactly those assets. They spent years negotiating power purchase agreements, locking down industrial sites near cheap electricity, and building out the cooling and electrical infrastructure needed to run thousands of machines at full tilt. Swapping out mining rigs for GPU clusters is, relatively speaking, the easy part.
