Jane Street Reports Over $1B in Spot Bitcoin ETF Shares in Q2 13F

Quant trading firm Jane Street reported holding more than $1 billion in U.S. spot Bitcoin ETF shares as of June 30, according to its second-quarter Form 13F. The firm's largest disclosed position was BlackRock's iShares Bitcoin Trust (IBIT), valued at about $828 million, with additional exposure listed in Fidelity's FBTC and Grayscale's GBTC. The filing reflects reportable ETF securities held at quarter-end, not direct Bitcoin ownership, and it does not indicate whether the exposure was hedged. As a market maker and liquidity provider, Jane Street's ETF inventory can be tied to arbitrage, hedging, or client flow rather than a long-term directional view. Jane Street's IBIT position increased sharply from the prior quarter. As of March 31, it reported roughly 5.9 million IBIT shares worth about $225 million. The 13F also does not show when the firm acquired the shares or the prices paid, and it omits much of the broader trading book, including many short positions and derivatives. Bitcoin was up 1.19% over 24 hours to $64,268.03 at the time referenced in the report. Jane Street's next 13F will report positions as of Sept. 30. The SEC lists Nov. 16, 2026, as the deadline for third-quarter filings. Disclaimer: This content is for informational purposes only and does not constitute financial advice.
