Jane Street Cuts Bitcoin Exposure by 71% as Ether Position Rises to $82M in Q1
"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. The pullback came during a turbulent stretch for digital assets, with bitcoin trading below $80,000 during parts of the quarter as broader crypto markets faced sustained selling pressure."
"Jane Street also cut exposure to Strategy, with the firm reducing its Strategy position from roughly 968,000 shares to about 210,000 shares, lowering the reported value of the stake from nearly $146 million to approximately $27 million. The reversal was notable given that earlier filings showed Jane Street had increased its Strategy holdings by more than 470% in the previous quarter. The firm additionally trimmed positions in several bitcoin mining companies, including IREN, Cipher Mining, Terawulf, and Core Scientific."
"At the same time, Jane Street increased its exposure to ether-related investments. Holdings in Blackrock’s Ishares Ethereum Trust nearly doubled during the quarter, while the firm also expanded its position in Fidelity’s ethereum fund. 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."
