Jane Street sharply reduced several major bitcoin-linked positions during the first quarter while increasing exposure to ether ETFs and selected crypto equities. The portfolio changes came amid heightened market volatility and shifting institutional sentiment toward digital assets.
Key Takeaways:
Jane Street Group, one of Wall Street’s most influential trading firms, cut back key bitcoin-related investments during the first quarter of 2026 while increasing exposure to ether-focused funds and select crypto equities, according to a new regulatory filing.
The firm’s latest 13F filing showed significant reductions in spot bitcoin exchange-traded funds managed by Blackrock and Fidelity, reversing part of the aggressive positioning it had built late last year.
Holdings in Blackrock’s iShares Bitcoin Trust fell roughly 71% quarter over quarter to about 5.9 million shares, valued at approximately $225 million at the end of March. Jane Street also reduced its stake in Fidelity’s Wise Origin Bitcoin Fund by around 60% to nearly 2 million shares, worth about $115 million.
