Summary
Leopold Aschenbrenner's hedge fund, Situational Awareness, has established a substantial bearish options strategy against leading semiconductor and AI infrastructure companies, according to regulatory filings disclosed on May 18, 2026. The fund accumulated over $1.5 billion in put options on Nvidia during the first quarter of 2026, alongside approximately $2 billion in puts on the VanEck Semiconductor ETF (SMH). Puts represent bets that underlying asset prices will decline, making this positioning a direct counter to the technology sector's AI-driven rally that has dominated market sentiment.
Beyond Nvidia, the fund's 13F filing reveals extensive bearish positions across the semiconductor supply chain. Notable put positions include $1.07 billion against Oracle, $1 billion against Broadcom, $969.2 million against Advanced Micro Devices, $535.1 million against Taiwan Semiconductor Manufacturing Company (TSMC), $494.1 million against ASML Holding, and $159.1 million against Intel. These positions aggregate to several billion dollars in bearish bets against foundational AI infrastructure companies.
Aschenbrenner's credibility within AI research circles lends institutional weight to this contrarian stance. The former member of OpenAI's alignment team gained prominence in 2024 with his white paper "Situational Awareness: The Decade Ahead," which articulated systemic concerns regarding rapid AI advancement. He launched Situational Awareness hedge fund approximately three months after the paper's publication, establishing a vehicle to operationalize his strategic views on technology sector trajectories.
The fund's positioning reflects a nuanced outlook rather than blanket bearishness. Concurrent long positions and call options on other segments of the AI infrastructure ecosystem suggest Aschenbrenner maintains bullish conviction in specific areas of artificial intelligence development and deployment, despite his aggressive shorts against chip manufacturers. This selective strategy indicates differentiated views on which subsectors of the AI trade face overvaluation or fundamental headwinds.
The disclosure arrives as institutional skepticism toward the semiconductor rally has intensified among sophisticated investors, signaling potential reassessment of valuations and growth assumptions embedded in current AI hardware stocks. Aschenbrenner's positioning represents a high-profile institutional bet against consensus market direction in a sector that has benefited substantially from retail and institutional capital rotation into AI-related equities.
