Jane Street expands Fidelity Bitcoin ETF position nearly eightfold while reducing IBIT exposure

The trading firm concluded Q3 holding 19% fewer shares of BlackRock's Bitcoin ETF, though rising prices pushed the position's value up to $957 million.

The trading firm Jane Street dramatically increased its position in Fidelity's spot Bitcoin exchange-traded fund (ETF) during the third quarter by nearly eightfold, even as it reduced its exposure to BlackRock's competing fund by 19%.

By the conclusion of September, the trading powerhouse held 7.01 million shares of the Fidelity Wise Origin Bitcoin Fund (FBTC), a substantial increase from approximately 887,000 shares held at June's end. Based on its second-quarter and third-quarter regulatory filings, the position carried a value of $509 million as of Sept. 30.

Meanwhile, Jane Street's position in the iShares Bitcoin Trust ETF (IBIT) from BlackRock decreased to 20.22 million shares from the previous 24.88 million. Despite this reduction in share count, an increase in the share price boosted the disclosed value of this holding to $957 million, up from $828 million.

By the conclusion of June, Jane Street ranked as the largest disclosed institutional shareholder of BlackRock's Bitcoin ETF following a 324% increase in its share count during Q2, based on data from 13F Pro. With $56 billion in net assets as of Thursday, IBIT holds the distinction of being the world's largest spot Bitcoin ETF.

Additionally, the firm purchased nearly 9 million shares (valued at approximately $249 million) of the ARK 21Shares Bitcoin ETF (ARKB), and more than doubled its stake in BlackRock's iShares Ethereum Trust ETF (ETHA) by acquiring 7.83 million shares (valued at roughly $158 million).

JPMorgan adds IBIT shares as Laurore cuts stake

During the third quarter, JPMorgan Chase expanded its IBIT holdings by 9.6%, purchasing approximately 1 million additional shares to bring its total to 11.41 million. The American banking behemoth's disclosed IBIT position climbed to roughly $540 million.

Conversely, JPMorgan almost completely eliminated its direct stake in BlackRock's ETHA, slashing its position from 1.17 million shares held at the close of June to a mere 399 shares.

Additionally, the bank expanded its holdings in Strategy, a Bitcoin treasury company, by 36% to reach nearly 849,000 shares, representing approximately $131 million in value at Q3's conclusion.

Laurore, an entity that reports a Hong Kong business address in its SEC filing, decreased its IBIT holdings by 33%, reducing its position by 1.6 million shares to reach 3.25 million, valued at approximately $154 million by Q3's end. The firm garnered significant attention in February 2026 following the disclosure of an IBIT position valued at $436 million at the conclusion of 2025.
