Leopold Aschenbrenner's $20 billion AI fund is asking for fresh capital after a rough July, FT reports

Situational Awareness, the roughly $20 billion hedge fund former OpenAI researcher Leopold Aschenbrenner built in under two years on a 439% net return through the first half of 2026, has approached existing investors and lenders for fresh capital after a sharp July reversal in AI stocks, the Financial Times reported. Some investors were reportedly offered the option to buy portfolio assets directly rather than commit new cash outright. The reporting traces entirely to FT's review of an internal letter — neither Aschenbrenner nor the fund has commented publicly, and independent confirmation beyond that reporting was not possible.

Per FT's reporting, the fund's Q1 2026 portfolio disclosures showed concentrated positions including Bloom Energy, CoreWeave, and Nebius — all hit hard in the rout — plus a new $43.9 million stake in T1 Energy, a 92.4% increase in its Bitdeer Technologies holding, and 3.39 million shares of HIVE Digital Technologies. Goldman Sachs and JPMorgan Chase separately issued margin calls to hedge funds holding concentrated AI positions during the same selloff, a sign the pressure wasn't unique to this one fund.

In a July 24 letter FT reviewed, Aschenbrenner reportedly framed the downturn as a buying opportunity and pointed to a potential [Anthropic](#/company/anthropic) IPO as a forward catalyst for the sector, while inviting investors to commit additional capital starting August 1. That framing is reported content from the fund's own letter, presented as such — not an assessment of whether the fund's positions will actually recover.
