Citadel snaps up Anthropic assets after fund margin call
- Leopold Aschenbrenner's $45 billion fund collapsed after debt-heavy tech bets triggered automatic bank sell-offs.
- Citadel bought the liquidated portfolio at deep discounts, securing private stakes in Anthropic and compute facilities.
- Wall Street funds shorted Aschenbrenner’s holdings, turning a temporary price dip into a permanent liquidation.
The liquidation was instantaneous. Lenders didn't ask questions before selling off Leopold Aschenbrenner's portfolio.
Former OpenAI researcher Leopold Aschenbrenner built his Situational Awareness fund from $225 million in 2024 to a peak of $45 billion. But running four dollars of debt for every dollar of cash left no room for error. When chip stocks took a 20 percent hit in a single month following a hawkish tone from the Federal Reserve, automatic margin calls kicked in. Lenders stepped in immediately, clearing out public holdings to shield their balance sheets.
Wall Street sharks quickly turned the forced unwind into a targeted squeeze. On Forward Guidance, the discussion highlighted how rival funds shorted every position listed in Aschenbrenner’s public filings, accelerating the drop. Ken Griffin’s Citadel moved in at the bottom, scooping up the entire liquidated portfolio at a steep discount - including private stakes in Anthropic.
The fallout extends far beyond paper equities. On Simon Dixon Hard Talk, Simon Dixon explained that Citadel’s buying spree focused heavily on physical compute and power allocations. Citadel secured a cornerstone stake in Ionic Digital, a former Bitcoin miner that pivoted into high-performance AI computing following the Celsius bankruptcy. Controlling the underlying data centers and energy contracts provides a permanent advantage that outlasts short-term market swings.
The disaster exposed the danger of using borrowed cash to chase market momentum. On All-In, David Sacks noted that the semiconductor crash was driven by over-extended traders rather than failing technology. Meanwhile, on This Week in Startups, Jason Calacanis pointed out that taking on excessive debt left Aschenbrenner defenseless when volatility struck. Even with vast private assets intact, the forced liquidation wiped out public gains in days.
That psychological damage will take months for tech investors to digest. As David Friedberg argued on All-In, surging Treasury yields reflect mounting fiscal pressures that only massive AI productivity gains can offset. But as capital concentrates among institutional giants who bought up distressed infrastructure, power over the AI economy shifts from visionary founders to balance-sheet titans.
In the end, momentum built the fund, but debt destroyed it.

Markets (5)
- The AI trade unwind saw Leopold Ashbrer's fund, which grew from an initial $225 million to billions, forced to liquidate its public and some private market positions, with Ken Griffin's Citadel reportedly buying the assets.
- The Host notes that the AI trade's prior growth was heavily driven by leverage, including 3x retail ETFs and Korean margin calls, suggesting that a return to peak levels would be difficult without similar leverage.
- Quinn points out that the first meaningful earnings miss from SK Hynix coincided with maximum leverage in the system and increased short-selling activity by firms targeting large, vulnerable players.
- The Host emphasizes that market price often drives narrative, rather than the reverse, evidenced by varied explanations for the AI trade's decline until leverage liquidations became the clear cause.
- Quinn highlights that while nominal yields across the curve didn't show the full picture, the 30-year duration saw higher real yields, aligning with the argument that the long end has been suppressed by Fed intervention.
Fed (6)
- The Fed, led by Kevin Worsh, paused interest rate hikes with three dissents, despite market odds suggesting a 60% chance of a pause and 40% for a hike, unsettling bond investors with perceived communication issues.
- Nick Timiraos, citing Marabana from Bank of America, characterized the Fed's communication as a 'classic central bank credibility shock,' causing the long end of the curve and stocks to turn as investors doubted the chairman's willingness to deliver further hikes.
- Kevin Worsh's press conference unsettled investors due to uncertainty regarding the Fed's inflation gauge, with Worsh stating his own 'lens is broader' than the official PCE and suggesting the central bank's strategy statement could change.
- The Host argues that Worsh clearly signaled a desire to remove balance sheet accommodation from the long end of the Treasury market to allow free market pricing, which would restrict financing conditions and widen credit spreads.
- The Host asserts that Worsh's strategy implies that allowing the long end to reprice higher by 50-100 basis points, without direct rate hikes, would sufficiently slow the economy and inflation, making aggressive front-end hikes unnecessary.
- Quinn speculates that by avoiding a hike today, the Fed is making a bet that tightening financial conditions through long-end focus, combined with external factors like the Iran war, will stabilize the economy by the September meeting, allowing them to avoid a pre-midterm hike.
Macro (1)
- The Host believes many 'big boosts' to growth, such as the World Cup, 'one beautiful bill' stimulus, and stock market wealth effects, are evaporating, suggesting growth estimates will likely decline over the next two to three quarters.
Politics (1)
- The Host suggests that the current administration has a history of creating volatility events to achieve policy goals and will likely manufacture favorable outcomes, especially as midterms approach, rather than maintaining long-term hawkish resolve.
Why AI has no taste and how to fix it (w/ Thais Castello Branco) | E2319 • Jul 31
- Jason describes using "Athena assistants" (AI) to aggregate data from sources like Monocle magazine and specific searches to generate personalized "cool hunting" reports for travel and design preferences, acting as his curated stack.
- Leopold Aschenbrenner's AI hedge fund, Situational Awareness, amassed $45 billion AUM and a 439% return, but 4x leverage led to margin calls and a public portfolio sale to Citadel. Jason attributes this to Aschenbrenner's inexperience and "pile-on" tactics.
- Google integrated its "Nano Banana" AI image generator into Google Earth, allowing users to manipulate satellite and Street View images. Lon and Jason express concern over the significant misinformation potential, citing examples like generating fake refugee camps.
- LinkedIn removed its "enhance with AI" button due to low-quality content, while Substack implemented anti-AI tools, fearing an influx of "AI slop." Jason suggests platforms should shadowban AI-generated posts, noting young people already perceive AI as "lame."
