Wall Street market maker Jane Street reduced its exposure to Bitcoin exchange-traded funds (ETFs) in the first quarter of 2026 while increasing positions in Ether funds.
Jane Street cut major Bitcoin ETF holdings in Q1 2026, including BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity Wise Origin Bitcoin Fund (FBTC),accordingto a 13F filing published Tuesday.
IBIT holdings fell about 71% fromQ4 2025to roughly 5.9 million shares valued at about $225 million, while FBTC dropped about 60% to around 2 million shares worth roughly $115 million.
At the same time, Jane Street increased its exposure to Ether (ETH) ETFs, nearly doubling its position in BlackRock’s iShares Ethereum Trust (ETHA) and sharply raising its stake in Fidelity Ethereum Fund (FETH), adding about $82 million combined across the two products over the quarter.
The move comes amid early signs of institutional Ether ETF buying in early 2026,including increased exposure reported at Wells Fargo. The filing points to a reshuffling of Jane Street’s reportable crypto-linked holdings at quarter-end, though 13F disclosures do not show the market maker’s full trading book or net exposure.
Jane Street’s Bitcoin-linked exposure weakened further in Q1 2026 as it reduced its stake in Michael Saylor’s Strategy (MSTR) alongside major ETF cuts.
In Q4 2025, the firm held about 968,000 MSTR shares worth roughly $145.9 million. By Q1 2026, the common stock stake fell to about 210,000 shares valued at roughly $27 million, a decline of about 78% quarter-over-quarter.
