Jane Street increased its holdings of Fidelity’s Wise Origin Bitcoin Fund (FBTC) from 886,736 to 7,010,008 shares between the end of June and September 30, 2026, raising their value from $45.3 million to $509.2 million. The firm simultaneously cut its stake in BlackRock’s iShares Bitcoin Trust (IBIT) by 19%, although the position’s value rose from $828.2 million to $957.3 million as ETF prices advanced. It also acquired nearly 9 million shares of ARK 21Shares Bitcoin ETF (ARKB), worth around $249 million, and more than doubled its position in iShares Ethereum Trust (ETHA). Jane Street’s combined holdings of FBTC, IBIT and ARKB were worth approximately $1.79 billion, according to its SEC Form 13F filed on November 12, 2026. These positions, measured as of September 30, may partly reflect Jane Street’s inventory as a market maker and authorized participant rather than a straightforward directional view on Bitcoin.
