Jane Street Slashes Bitcoin ETF Holdings, Adds Ether Funds In Q1 2026

Authored by Helen Partz via CoinTelegraph.com,

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), according to a 13F filing published Tuesday.

IBIT holdings fell about 71% from Q4 2025 to 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.

Bitcoin exposure weakens further as Strategy stake falls

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.

Strategy selling followed significant buying in the previous quarter as Jane Street reportedly increased MSTR position by 473% in Q4 2025.

In Q1 2026, the company also trimmed exposure across several Bitcoin mining stocks, including IREN, Cipher Mining, TeraWulf and Core Scientific.

Increased exposure to Coinbase, Galaxy and Riot

Despite broad downside pressure on Bitcoin-related assets, Jane Street increased exposure to several crypto-linked equities over the quarter, suggesting more selective positioning in crypto-related equities rather than a broad exit from the sector.

Jane Street raised its stake in the crypto mining company Riot Platforms (RIOT) to about 7.4 million shares, up from 5 million, increasing its value to roughly $91 million from $63 million.

It also increased its position in Coinbase (COIN) to about 888,000 shares from 778,000, with the value rising to about $155 million from $176 million in the prior quarter.

Galaxy Digital (GLXY) saw the sharpest expansion, jumping to about 1.5 million shares from just around 17,000, lifting its value to roughly $28 million from around $380,000.

Jane Street posted a record $16.1 billion in Q1 trading revenue, according to Reuters, as volatile markets and gains tied to artificial intelligence-related investments boosted financial results.
