Aschenbrenner shorts chip stocks

Leopold Aschenbrenner’s hedge fund used its latest U.S. regulatory filing to show a very specific AI-market view: hedge the chip layer, own more of the infrastructure beneath it. A May 18 Form 13F from Situational Awareness LP, the San Francisco fund run by the former OpenAI researcher, showed new put positions tied to major semiconductor names and the VanEck Semiconductor ETF, while outside reports tied the same portfolio shift to larger bets on miners and energy-linked infrastructure. The filing landed two days before Nvidia’s scheduled earnings, giving traders a fresh data point on how one closely watched AI investor is repositioning. Reports from Benzinga, TradingKey and CoinDesk all described the move as a rotation away from pure chip exposure and toward compute, power and physical buildout. ### Which positions made this filing stand out? Situational Awareness LP filed its latest 13F on May 18 for holdings as of March 31, according to SEC records. Third-party summaries of the filing said the fund added put exposure worth about $8 billion to $8.5 billion in notional value against parts of the semiconductor complex, including Nvidia, Broadcom, AMD and the VanEck Semiconductor ETF. Benzinga also said Oracle was among the names targeted. (sec.gov) CoinDesk reported on May 18 that Aschenbrenner had also increased bets on bitcoin miners and AI infrastructure companies. TradingKey, citing CoinDesk, said the portfolio shift reflected a view that the “second half” of the AI race would be more about power than chips. ### Why would an AI investor short chips while staying in the theme? (sec.gov) Leopold Aschenbrenner has been publicly associated with the view that advanced AI progress will be constrained by real-world bottlenecks, not only model research. The new filing does not spell out a narrative in his own words, but market coverage around the disclosure converged on the same explanation: the fund appears to be hedging richly valued chip stocks while keeping exposure to the broader AI buildout through adjacent infrastructure. (coindesk.com) That is an inference from the portfolio mix and outside reporting, not a direct quote from the filing itself. DIGITIMES reported that OpenAI had surpassed 900 million weekly active ChatGPT users and had signaled possible additional fundraising as compute demand outstripped available resources. That report offered a separate, contemporaneous marker for the same market concern: demand for AI services is rising faster than available compute and supporting capacity. ### Why are miners and energy names part of this trade? (benzinga.com) CoinDesk said Aschenbrenner’s fund increased bets on bitcoin miners and AI infrastructure companies, and follow-on market coverage linked the move to companies that can supply power, sites or power-dense facilities for AI workloads. In current market logic, miners are relevant because some already control large electrical loads, data-center-style facilities or power contracts that can be repurposed for AI compute. (digitimes.com) Benzinga’s report framed the shift as a wager that electricity and physical infrastructure could become tighter constraints than additional chip demand alone. TradingKey used nearly the same framing in describing the book as a pivot from semiconductors toward “miners and AI energy.” (coindesk.com) ### What can and can’t a 13F actually tell you? A 13F shows long U.S. equity holdings and certain listed options as of a quarter-end date, not real-time positions. The May 18 filing therefore captures Situational Awareness LP’s book as of March 31, and it does not reveal whether positions have since been trimmed, expanded or offset elsewhere. WhaleWisdom, which tracks 13F disclosures, said Situational Awareness LP’s latest filing covered about $13.68 billion in 13F securities, while its Form ADV listed about $9.28 billion in discretionary assets under management as of April 27. (benzinga.com) Those figures help explain why the options notional attached to the short-chip theme drew attention across trading desks. (sec.gov) ### What happens next? Nvidia is due to report earnings this week, and the timing matters because Aschenbrenner’s filing arrived just before one of the market’s most important AI readouts. The next formal update from Situational Awareness LP will come with its subsequent 13F filing after the June quarter, while the current filing remains available on SEC EDGAR and the trade thesis is already being parsed across market outlets.
