Summary

Jane Street increased its Fidelity Bitcoin ETF holdings by 691%, reaching 7.01 million shares worth $509.2 million.
The trading firm reduced its BlackRock IBIT share count by 18.7%, although the stake’s value rose to $957.3 million.

Jane Street increases Fidelity Bitcoin ETF shares by 691%

The addition of 6,123,272 FBTC shares represents an approximately 691% increase in the number held during Q3. The September position was almost 7.9 times the June figure, making Fidelity a much larger part of Jane Street’s reported Bitcoin ETF holdings.

The latest change reverses part of the firm’s earlier retreat from Fidelity’s fund. As crypto.news previously reported, Jane Street reduced its FBTC shareholding by around 60% in the first quarter, when it cut its BlackRock Bitcoin ETF exposure.

Its second-quarter filing showed an increase in BlackRock shares to nearly 24.88 million, with that holding worth $828.2 million at June 30. Jane Street’s combined Bitcoin ETF holdings had already exceeded $1 billion by then, led by IBIT.

The Q3 data reveal a different distribution among the funds. Based on the share positions reported for FBTC, IBIT and ARK 21Shares Bitcoin ETF (ARKB), their combined quarter-end value rose from approximately $926 million in June to $1.79 billion in September.

BlackRock IBIT shares fall even as stake value grows

In BlackRock’s iShares Bitcoin Trust ETF (IBIT), Jane Street reported 20,221,140 shares at the end of September, down from 24,878,191 at June 30. The reduction of 4,657,051 shares works out to 18.7% of its earlier holdings.

Despite that decline, the reported value increased to $957.3 million from $828.2 million.

The same 13F filing listed options related to IBIT separately from the ordinary fund shares. Jane Street reported call options referencing 34.97 million IBIT shares and put options referencing 45.32 million.

BlackRock listed approximately $56.3 billion in net assets for IBIT as of November 12, making it the largest U.S. spot Bitcoin ETF by assets.

Moreover, the firm’s ARKB holding grew from 2,700,151 shares at the end of June to 11,689,194 shares by September 30. It added nearly 8.99 million shares over the quarter, leaving a position valued at $323.7 million, compared with $52.5 million previously.

Jane Street expanded its holding in BlackRock’s iShares Ethereum Trust ETF (ETHA) as well. The reported share count rose from 7,606,021 to 15,438,249, a gain of approximately 7.83 million shares. At September’s close, the ETHA stake was valued at about $310.6 million, against $90.4 million at June 30.

JPMorgan raises IBIT holdings while Laurore reduces them

Other institutions reported different changes in BlackRock’s Bitcoin fund. JPMorgan Chase’s November 12 13F filing showed 11.41 million IBIT shares worth approximately $540 million, up about 1 million shares, or 9.6%, from the previous quarter.

The bank’s BlackRock Ethereum ETF share position fell to just 399 shares from roughly 1.17 million at the end of June.

Meanwhile, Hong Kong-based Laurore cut its IBIT position by 1.6 million shares to 3,246,279, worth approximately $153.7 million. That was a 33% drop in its share count during the quarter.

The latest disclosures follow Barclays’ reported 48% increase in IBIT shares and Citigroup’s new 1.64 million-share FBTC position at September 30. Both banks filed their third-quarter holdings before Jane Street’s November 12 submission.
