Leopold Aschenbrenner, Founder at Situational Awareness LP

AI infrastructure investing, the disclosed Bloom position, and the Citadel portfolio transaction

What is known now

The SEC confirms what Situational Awareness reported holding on March 31. Reuters and Axios confirm a later sale of the public-stock portfolio to Citadel after losses. The exact four-times leverage and margin-call sequence come from commentary and remain unverified.

What JMM tracks
The difference between the Situational Awareness essay and fund, what its Q1 2026 Form 13F disclosed, what Reuters and Axios reported about the later Citadel deal, and why the exact leverage and margin-call story is still not established.

Three evidence layers that should not be merged

Every statement carries its quote, its source, its date and its review state. A verdict only ever comes from a documented record, per the publication standard.

Filing record Open
At March 31, Situational Awareness disclosed Bloom common stock and Bloom call-option exposure on Form 13F.

The filing lists common stock at $878,707,930 and 6,485,408 shares, plus calls with a reported value of $55,347,665 and 408,500 underlying shares. A 13F is a delayed quarter-end snapshot. It does not disclose the later sale price, the fund’s full portfolio, its financing, or whether it still owned the position after March 31.

Source record Open
Reuters reported that Situational Awareness sold the bulk of its stock portfolio to Citadel after heavy technology losses.

Reuters reported the transaction through sources familiar with the matter. Crucially, its report said it was unclear whether margin calls preceded the deal. That sentence rules out presenting a margin call as settled fact.

Source record Open
Axios reported that the public-equities portfolio was sold to Citadel while the fund was dealing with losses and seeking fresh capital.

Axios described a sale of all public equities. That does not establish that every asset of the firm was sold. Public stocks, private investments, cash, liabilities, and the management company are different things.

Attributed paraphrase Under review
Camillo estimated roughly four-times exposure and described a margin-call chain, but those details are not independently established.

Attributed paraphrase from 04:35 and 06:06 of the August 9 interview. Camillo also described a roughly 40% drawdown at 02:25. JMM has not located a lender notice, fund statement, or regulatory record proving those exact figures. Reuters expressly left the margin-call timing unclear.

The playbook, sourced

The essay explains an AI-infrastructure thesis. The filing shows selected quarter-end holdings. Neither one discloses the financing that determined how long the fund could hold them.

Treat compute and power as the bottleneck

Aschenbrenner’s 2024 essay argues that scaling advanced AI requires a very large buildout of chips, data centers, and electricity. The Q1 2026 filing is consistent with an infrastructure theme, but a 13F cannot prove why each security was owned or how it was financed.

Where the rules stop working

Every rule above is a shortcut that holds inside a range of circumstances. These are the edges. Entries carrying a link are somebody else's published objection; the rest are JMM's own reading of the arithmetic.

The desk's read

The clean story is not that an AI thesis was disproved. It is that a concentrated portfolio can lose control of its own timeline. A manager can be right about a decade and still be unable to hold through a month.

The filing, the transaction, and the margin-call narrative belong in three separate boxes. Combining them produces a vivid story. Keeping them separate produces a reliable one.

Opinion, not a rating. JMM publishes no reputation score for any person, and nothing here is personalised advice.
