Summary
Jane Street Group, a preeminent Wall Street trading firm, materially reduced its spot bitcoin ETF exposure during the first quarter of 2026 while simultaneously increasing allocations to Ethereum-focused instruments and selective cryptocurrency equities, according to 13F regulatory filings disclosed in May 2026. The firm's holdings in BlackRock's iShares Bitcoin Trust (IBIT) declined approximately 71% quarter-over-quarter to 5.9 million shares valued at roughly $225 million as of March 31. Additionally, Jane Street cut its position in Fidelity's Wise Origin Bitcoin Fund (FBTC) by around 60% to approximately 2 million shares worth $115 million. The pullback marked a strategic reversal from the aggressive bitcoin positioning the firm had accumulated in late 2025.
The repositioning occurred during a challenging period for digital assets, with bitcoin trading below $80,000 during portions of Q1 2026 amid broader crypto market weakness and sustained selling pressure. Jane Street's reduction in bitcoin exposure stood in sharp contrast to JPMorgan Chase's contrarian positioning. The banking giant increased its Bitcoin ETF holdings by 174% during the same quarter, led by significant additions to BlackRock's IBIT, demonstrating clear institutional divergence in crypto allocation strategies.
Rather than exiting crypto entirely, Jane Street diversified its digital asset exposure. The firm added $82 million to ether-focused ETFs and nearly doubled its position in the iShares Ethereum Trust. The firm also increased holdings in Galaxy Digital Mining to 1.5 million shares while boosting stakes in Riot Blockchain and Coinbase. These moves reflected a strategic shift from concentrated bitcoin exposure toward a more diversified cryptocurrency and crypto-equity portfolio.
Beyond spot ETF positions, Jane Street trimmed exposure to bitcoin mining companies during the quarter. The firm significantly reduced its Strategy Holdings position from approximately 968,000 shares valued at nearly $146 million to roughly 210,000 shares worth $27 million, reversing a prior period increase of more than 470%. Holdings in IREN, Cipher Mining, Terawulf, and Core Scientific were also reduced, signaling a broader pullback from direct mining sector exposure during a period of cryptocurrency market volatility.
