Crypto: Ex-openai Researcher’s Hedge Fund Reveals Big Bitcoin Miner Bets In...

Leopold Aschenbrenner’s hedge fund Situational Awareness LP has scaled to $5.52 billion in equity exposure in less than a year by betting on power, data centers and Bitcoin miners.

Leopold Aschenbrenner has built a US stock portfolio heavily concentrated in companies that supply the power and infrastructure behind the artificial intelligence boom.

The former OpenAI researcher, who left the lab’s superalignment team to launch San Francisco-based hedge fund Situational Awareness LP, has expanded it from $383 million in assets in early 2025 to a reported $5.52 billion in equity positions in its latest 13F filing with the US Securities and Exchange Commission.

The fund’s 13F filing for Q4 2025 shows a highly concentrated portfolio built around betting that the real winners of the AI boom won’t be chatbots, but the power plants and data centers that feed them. Situational Awareness reported $5.52 billion in US equity positions across 29 holdings, with a large share of that value clustered in a handful of AI infrastructure names.

Those include graphics processing unit (GPU) cloud provider CoreWeave, fuel cell and power specialist Bloom Energy, Intel, optics maker Lumentum and Bitcoin (BTC) miner-turned-AI infrastructure play Core Scientific.

Aschenbrenner first drew attention as a precocious AI thinker after publishing a widely read “Situational Awareness” manifesto on the race to advanced AI, then quickly parlayed that profile into capital. His San Francisco-based AI hedge fund now manages more than $1.5 billion, backed by prominent tech founders, family offices and institutions.

Aschenbrenner has been a substantial net buyer quarter-on-quarter, with Situational Awareness’ 13-F reported US equity and options portfolio increasing from about $254 million in Q4 2024 to more than $5.5 billion by Q4 2025. Over that period, the fund built sizable positions in Bitcoin miners and related energy infrastructure firms including IREN, Cipher Mining, Riot Platforms, Bitdeer and Applied Digital.

The bet aligns with a broader shift already reshaping Bitcoin mining. After the latest halving squeezed block rewards, large miners have started repurposing their high-density, power-rich sites as AI hosting hubs, treating megawatts and data center space as scarce assets in the new compute economy rather than just hashrate.
