Jane Street Reports $15B July Losses From AI Fund Pullback

Jane Street incurred $15B in July losses due to Situational Awareness fund drawdowns, yet annual trading revenue has already surpassed the $39.6B target.

Woofun AI reports that Jane Street recorded approximately $15 billion in losses during July, primarily driven by a sharp correction in its investment in the AI-focused hedge fund Situational Awareness and other technology equities. Despite this monthly deficit, the firm's cumulative trading revenue for the year has exceeded $40 billion, surpassing its full-year 2025 target of $39.6 billion and outperforming major global banks.

An internal memo described July as a "terrible month," noting that Situational Awareness had expanded positions following strong first-half performance before facing significant margin calls amid the AI sector downturn. The fund subsequently sold most stock positions to Citadel. Jane Street also cited losses from long positions in Asian non-AI stocks and a roughly 50% decline in large storage and semiconductor shares, though returns on the AI investments remain above initial cost basis.
