Key Takeaways
- • Situational Awareness held approximately $11 billion in combined positions in Micron Technology and SanDisk as of June 30, 2026, representing roughly 25% of the hedge fund's net assets, according to Bloomberg's analysis of portfolio disclosures.
- • The fund reduced options positions in major AI beneficiaries including Nvidia, Broadcom, and Advanced Micro Devices during the second quarter, but maintained and increased exposure to memory-chip makers Micron and SanDisk ahead of the July technology selloff.
- • Micron declined approximately 29% during July's semiconductor rout, while SanDisk plunged 47%, inflicting substantial losses on the highly leveraged fund despite its tactical repositioning efforts.
- • Accelerating losses on technology investments forced Situational Awareness to liquidate public equities, with Citadel subsequently acquiring a significant portion of the fund's AI-related stock holdings.
- • The portfolio adjustments, intended to derisk from peak valuations in Nvidia and peer stocks, proved insufficient to insulate the fund from the broader semiconductor sector collapse that followed in July.
Summary
Situational Awareness, the highly leveraged hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, maintained substantial exposure to semiconductor stocks Micron Technology and SanDisk heading into July's technology sector selloff. According to Bloomberg's review of portfolio disclosures, the fund held approximately $11 billion in combined positions across these two memory-chip makers as of June 30, 2026—a concentration representing roughly one-quarter of the fund's net assets at that time.
The fund's second-quarter portfolio adjustments reveal a deliberate tactical shift within the technology sector. While Situational Awareness trimmed options positions tied to prominent AI infrastructure beneficiaries—including Nvidia, Broadcom, and Advanced Micro Devices—it simultaneously increased its holdings in Micron and SanDisk. This rebalancing reflected the fund's aggressive positioning around semiconductor infrastructure underpinning the artificial intelligence boom. However, the strategy failed to provide meaningful downside protection when markets reversed sharply in July.
The July technology selloff inflicted severe losses on the concentrated positions. Micron declined approximately 29% during the month, while SanDisk experienced a more severe 47% plunge. These declines, combined with broader losses across technology investments, forced Situational Awareness to liquidate public equities as portfolio damage accelerated. The fund's leverage amplified the impact of these equity declines, ultimately necessitating asset sales. Citadel, the multi-strategy fund founded by Ken Griffin, subsequently acquired a substantial portion of Situational Awareness's AI-related stock holdings, capitalizing on the distressed positioning.
The episode underscores the risks inherent in concentrated sector exposure and the limitations of tactical portfolio adjustments when executed immediately before sector-wide reversals. While Situational Awareness's reduction of options exposure to peak-valued names like Nvidia demonstrated risk-management awareness, its oversized allocation to memory-chip makers left the fund vulnerable to semiconductor sector weakness during the broader technology correction.
