Griffin: Citadel has offloaded over 80% of portfolio risk, buying at a discount is not about assets, but others' time pressure
Ken Griffin sent a letter to clients confirming that Citadel has offloaded over 80% of the overall risk from its original portfolio acquired from Situational Awareness through nearly 100 block trades, with a total market value exceeding $4 billion, and has quickly exited most of its vega risk.
In the letter, Griffin noted that discussions with Situational Awareness began on July 29, aimed at acquiring significant positions to strengthen the counterpart's balance sheet and reduce tail risk; the team completed a global portfolio analysis and pricing in just a few hours. The transaction was completed after a significant pullback in AI stocks and following margin calls faced by the counterpart, with an acquisition price at about a 10% discount.
The letter disclosed that nearly 100 block trades included the largest intraday block trade sizes for 10 different stocks that year. In the U.S. market, Citadel quickly exited the vast majority of its vega risk (the impact of expected volatility changes on the value of options positions), saving a substantial amount of capital. Griffin particularly thanked the trading and prime brokerage teams from both banks for their full cooperation, stating that such a large-scale portfolio transfer could not have been completed without their focused efforts.
Citadel's flagship multi-strategy Wellington Fund achieved a return of 5.94% in July, marking its best single-month performance since 2022, with a year-to-date return of about 12%. This acquisition occurred against the backdrop of Situational Awareness publicly disclosing a stock portfolio of approximately $16 billion, with about 4 times leverage and a portfolio value loss of about 67% in July, while retaining private holdings including shares of Anthropic.
AI-related stocks rebounded after Citadel's intervention, with the timing of Situational Awareness's sale close to the bottom of the sell-off that began in June. Citadel actively absorbed positions during market dislocations, leveraging its trading infrastructure and balance sheet capabilities, and quickly reduced market exposure after absorbing positions.
From a market mechanism perspective, Citadel, as a buyer, absorbed forced sales of AI-related stocks and options risk at discounted prices, subsequently reallocating through block trades to the market, with funds flowing from high-leverage AI thematic positions to more diversified risk bearers; the event-driven nature is evident, benefiting large multi-strategy institutions with rapid pricing and execution capabilities, while high-leverage single-theme funds and their financing banks are under pressure.

Citadel has previously absorbed distressed positions at discounted prices during market dislocations, including early interventions in Enron-related assets and providing liquidity support when other hedge funds faced forced liquidations; Griffin's team has repeatedly emphasized maintaining a "forward-leaning" posture during periods of stress over nearly 36 years, rather than relying on simple stop-loss mechanisms.
This capital path shows that Citadel mobilized its balance sheet quickly through its prime brokerage network and counterparties, completing the closed loop from due diligence to settlement within 24 hours, motivated by locking in high-volatility AI thematic exposure at a discount and quickly de-risking for profit during the rebound window, with resource mobilization focused on repricing and redistributing equity, options, and volatility instruments.
Similar cases can be seen with institutions like Millennium choosing to wait during similar sell-offs, while Jane Street experienced significant losses during the same AI pullback; the hedge fund industry is currently in a phase of transitioning from concentrated thematic strategies to diversified multi-strategy risk, with the rapid expansion and sudden contraction of single AI narrative funds highlighting mismatches in scale and liquidity.
Essentially, this is about capital concentration: a few large institutions with pricing, execution, and financing advantages absorb and redistribute risk during tail events, with the mechanism being the liquidity premium formed when high-leverage funds are forced to sell, allowing capital to shift from high-concentration thematic positions to platforms with infrastructure advantages.
