Leopold Aschenbrenner's Situational Awareness LP sold every public equity position it held on July 30 after prime brokers forced the unwind of a reportedly 4x-leveraged book, and Bitcoin miners were the unexpected beneficiaries. The long book was concentrated in power, AI compute, and Bitcoin miners: IREN, Core Scientific, Riot Platforms, CleanSpark, Applied Digital, HIVE Digital Technologies, and Bitdeer Technologies were all disclosed positions. The thesis Aschenbrenner built the fund around, that constrained energy and data-center capacity are the scarce input to AI scaling, is exactly what underpins Bitcoin miners' position in the power grid. What is clear: a single, unnamed buyer now holds the entire former Situational Awareness public book, including every disclosed Bitcoin miner position. If the gains hold or extend as the identity of the new book buyer becomes known, the thesis survives the stress test intact.
