Jane Street Discloses $990 Million Bitcoin ETF Stake as $15 Billion July Loss Clouds Snapshot
1 articles · Updated · Yahoo Finance · Aug 18
Summary
$990 million in bitcoin ETF holdings appeared in Jane Street’s June 30 SEC filing, with its biggest disclosed position in BlackRock’s iShares Bitcoin Trust.
The stake is a Form 13F snapshot of long ETF positions six weeks earlier and does not show current exposure; Jane Street acts mainly as a market maker and authorized participant, not a directional bitcoin investor.
Jane Street had already cut its IBIT stake by 71% in the first quarter while building ether ETF exposure, suggesting inventory rotation and hedging flow rather than a fresh bullish call on bitcoin.
The filing surfaced the same week Jane Street confirmed a $15 billion July trading loss—its worst month in about a decade—largely tied to its Situational Awareness AI hedge fund stake and weak Asian equity bets.
Even after that hit, Jane Street has generated more than $40 billion in trading revenue this year, above its full-year 2025 record of $39.6 billion; its next 13F is due in November.
