Summary
Jane Street substantially increased its cryptocurrency ETF exposure in the second quarter of 2026, disclosing significantly expanded positions in both Bitcoin and XRP instruments through its latest 13F regulatory filing. The quantitative trading firm's Bitcoin ETF holdings nearly doubled to $1.01 billion as of June 30, compared with $438.4 million three months prior—representing a $570 million net increase or 130% quarter-over-quarter growth.
The trading firm's Bitcoin strategy centers on BlackRock's iShares Bitcoin Trust (IBIT), which accounted for approximately $800.5 million of its total Bitcoin ETF exposure. This substantial position in IBIT persists despite Jane Street having reduced its IBIT stake by 71% in the preceding quarter, indicating a strategic rebalancing and reinvestment in the largest institutional Bitcoin ETF product. Beyond IBIT, Jane Street maintained diversified Bitcoin exposure through additional ETF holdings in Fidelity Wise Origin Bitcoin Fund (FBTC), ARK 21Shares Bitcoin ETF (ARKB), Bitwise Bitcoin ETF (BITB), and Grayscale Bitcoin Trust (GBTC).
More dramatically, Jane Street's exposure to XRP ETFs expanded more than fivefold in Q2, reaching approximately $17 million from $3.3 million in Q1—a $13.7 million increase representing 420% growth. The firm's largest XRP position comprised approximately $14.1 million held in the Bitwise XRP ETF, reflecting aggressive positioning in the emerging XRP spot ETF market alongside secondary holdings in additional XRP-focused exchange-traded products.
The scale of Jane Street's cryptocurrency ETF acquisitions, combined with its established role as an authorized participant in the Bitcoin and XRP ETF markets, indicates institutional adoption of spot crypto products has accelerated materially during the second quarter. The firm's simultaneous expansion across multiple Bitcoin ETF issuers and its rapid build-out of XRP exposure suggest continued confidence in both established and emerging cryptocurrency instruments among sophisticated market makers and quantitative trading operations.
