Shares of IREN, CleanSpark, Core Scientific, Riot Platforms, Bitdeer and HIVE Digital jumped as much as 27% after reports that Situational Awareness, the hedge fund founded by Leopold Aschenbrenner, had liquidated its public-stock portfolio. Situational Awareness's most recent 13F filing showed positions in all six names as of March 31, confirming the fund held sizable bets across bitcoin mining and AI data infrastructure.
Why it matters
The move matters less for who sold than for the positioning it implies. A $1 billion unwind by a fund that had publicly framed AI infrastructure as the dominant trade of the decade forces anyone short these names to rethink the catalyst that drove the bearish case. If the named underwriter of the AI-capex thesis is exiting publicly traded vehicles, the marginal seller is no longer an insider with information advantage. The squeeze is a positioning event.
Market impact
The names clustered around bitcoin mining plus AI data center exposure saw the largest moves, with IREN and Core Scientific leading the rally. Read-through is broader than the six: any small/mid-cap that pivoted from pure BTC mining into AI compute has been a crowded short in 2025 on thesis uncertainty about power contracts and hyperscaler demand. A clean unwind by a marquee holder removes one leg of that short.
Frequently asked questions
-
Who is Leopold Aschenbrenner and what is Situational Awareness?
Leopold Aschenbrenner is the founder of Situational Awareness, a hedge fund that built a public thesis around AI infrastructure as the dominant macro trade of the decade. The fund's recent 13F disclosed positions across bitcoin mining and AI compute names.
-
Which stocks surged on the liquidation report?
Shares of IREN, CleanSpark, Core Scientific, Riot Platforms, Bitdeer and HIVE Digital jumped as much as 27% after the news. Each appeared in Situational Awareness's most recent 13F filing dated March 31.
-
Why did bitcoin mining stocks spike on an AI fund selling?
Several of the names straddled bitcoin mining and AI data center exposure, so the fund's exit removed a major holder from a previously crowded-then-shorted trade. With the marquee seller gone, short sellers were forced to cover, driving the squeeze.
-
How large was the portfolio being unwound?
Reports pegged the Situational Awareness public-stock portfolio at roughly $1 billion, spread across the six bitcoin mining and AI infrastructure names disclosed in the 13F.
-
Does this affect Bitcoin's price directly?
Not directly. The move is an equity-flow event tied to a hedge fund's positioning in mining and AI infrastructure stocks, not a spot BTC supply or demand shift. The read-through for BTC is sentiment around the mining sector, not market structure.
