Traders on X (formerly Twitter) suspect AI researcher and investor Leopold Aschenbrenner, known for running hedge fund Situational Awareness, is behind a recent $96 million purchase of call options on AI stocks including SanDisk, Micron, Intel, and Marvell. These options are set to expire in two weeks on October 2. Although SEC filings have not yet disclosed the buyer, commentators like Jim Cramer and ZeroHedge have pointed to Aschenbrenner's past trading patterns and his fund's previous highly leveraged positions in the AI sector. Situational Awareness famously lost billions in a downturn in AI stock prices, leading JPMorgan Chase to terminate its lending relationship with the fund. The theory is based on pattern-matching rather than definitive proof, but SanDisk and Micron were among Aschenbrenner's largest positions in his fund's latest regulatory disclosure.
