Jane Street's latest disclosure to the SEC shows a trading firm leaning back into crypto ETFs after pulling back earlier in the year. The quant trading giant's Q2 2026 Form 13F, covering positions as of June 30, shows roughly $990 million in spot Bitcoin ETF holdings, with $828 million concentrated in BlackRock's iShares Bitcoin Trust and the remainder split across Fidelity's Wise Origin Bitcoin Fund and Grayscale's Bitcoin Trust. The full breakdown is laid out in Jane Street Group's 13F-HR filing on SEC EDGAR.
The jump is notable set against Q1: Jane Street had trimmed its IBIT position from roughly 20.3 million shares worth close to $790 million down to about 5.9 million shares worth $225 million during the first-quarter sell-off. The Q2 filing shows that retreat reversing, with the firm's overall Bitcoin ETF exposure climbing back toward the billion-dollar mark.
The bigger surprise is in XRP
Bitcoin wasn't the only crypto ETF category where Jane Street built up exposure. The firm's position in Bitwise's spot XRP ETF grew from just 20,605 shares at the end of Q1 to more than 1.2 million shares by June 30 — roughly a 60-fold increase in a single quarter. Jane Street also disclosed smaller XRP ETF positions through products from Franklin Templeton, Grayscale, Canary Capital and 21Shares, suggesting the buildup wasn't isolated to one issuer's product.

Market-making, not necessarily conviction
It's worth being precise about what a 13F position actually represents for a firm like Jane Street. As an authorized participant in these ETFs, Jane Street's holdings reflect its role creating and redeeming ETF shares to keep prices aligned with underlying assets, plus whatever inventory it carries to facilitate client and market flow — not necessarily a directional bet on price. That distinction matters for reading the filing correctly, even as the scale of the increase still points to real client demand flowing through Jane Street's desks for both Bitcoin and XRP exposure over the quarter.
Part of a wider institutional pattern
Jane Street's rebound mirrors a broader theme in Q2 crypto ETF flows: after the Q1 drawdown pushed several large holders to trim positions, many of the same names — Jane Street included — added back in over the following quarter as prices stabilized. BlackRock has argued that Bitcoin's investment case survives drawdowns like this one, and Jane Street's Q2 buildup is one of the clearer signs that at least some institutional money is trading on that logic. Whether the pattern holds through Q3, with Bitcoin still down sharply from its October highs, will show up in the next round of 13F filings due in November.
