Jane Street significantly reduced its Bitcoin-linked holdings in Q1 2026, cutting its positions in major Bitcoin ETFs and MicroStrategy (MSTR) shares. The firm slashed its stake in BlackRock’s iShares Bitcoin Trust by 71% to 5.9 million shares, valued at $225 million, and reduced its Fidelity Wise Origin Bitcoin Fund holdings by 60% to 2 million shares, worth $115 million. Additionally, Jane Street decreased its MSTR shares from 968,000 to 210,000, reflecting a strategic portfolio adjustment amid volatile markets. Conversely, Jane Street increased its exposure to Ethereum ETFs, nearly doubling its position in BlackRock’s iShares Ethereum Trust and adding to Fidelity’s Ethereum fund, totaling $82 million in new investments. The firm also boosted its holdings in crypto equities like Riot Platforms, Coinbase, and Galaxy Digital, indicating selective investment shifts rather than a complete exit from crypto assets. Jane Street's trading revenue reached a record $16.1 billion in Q1 2026, driven by market volatility and AI investments.
