Jane Street overhauled its crypto portfolio allocation in the third quarter of 2026. A Form 13F filing with the US Securities and Exchange Commission (SEC) dated November 12, 2026, shows the Wall Street trading firm increased its stake in Fidelity’s spot Bitcoin ETF (FBTC) nearly eightfold, surging 691%.
An addition of 6,123,272 new shares pushed the firm’s FBTC holdings to 7,010,008 shares as of September 30, 2026, valued at $509.2 million. That represents a sharp rise from its end-of-June position of 886,736 shares worth $45.3 million.
The aggressive buying of Fidelity’s product came alongside a reduction in exposure to the world’s largest asset manager.
Trimming BlackRock Shares Amid Rising Valuations
During the same period, Jane Street offloaded 18.7% of its holdings in BlackRock’s iShares Bitcoin Trust ETF (IBIT). The sale of 4,657,051 shares trimmed its stash from 24,878,191 shares to 20,221,140 shares. Despite holding fewer shares, the dollar value of Jane Street’s IBIT position actually rose from $828.2 million to $957.3 million, buoyed by Bitcoin’s price appreciation during the third quarter.
Beyond direct shares, Jane Street disclosed separate derivative positions on IBIT, holding call options on 34.97 million shares and put options on 45.32 million shares. Combined, the value of Jane Street’s spot Bitcoin ETF holdings across three major issuers - FBTC, IBIT, and ARKB - surged from $926 million at the end of June to $1.79 billion as of late September 2026.
Jane Street’s crypto exposure also expanded into Ethereum. The firm multiplied its holdings in BlackRock’s Ethereum ETF (ETHA) by purchasing an additional 7.83 million shares. This addition brought its total holdings to 15,438,249 shares valued at $310.6 million, up from $90.4 million on June 30.
Opposing Moves from JPMorgan and Global Banks
Jane Street’s capital allocation diverged sharply from JPMorgan Chase’s moves. In the same filing, JPMorgan increased its IBIT holdings by 9.6% to 11.41 million shares valued at $540 million. In Ethereum instruments, however, JPMorgan chose to offload nearly all of its ETHA holdings, dumping 1.17 million shares and leaving just 399 shares behind.
Portfolio reshuffling also took place across international asset management desks. Hong Kong-based investment entity Laurore reduced its IBIT stake by 33% to 3.24 million shares valued at $153.7 million. Conversely, Barclays increased its IBIT position by 48%, while Citigroup began building a new position by scooping up 1.64 million shares of FBTC.
For crypto market participants, these quarterly filings highlight an important reality: major Wall Street institutions do not move in lockstep. While JPMorgan offloaded almost all of its Ethereum exposure to add more Bitcoin, Jane Street chose to expand its positions in both assets simultaneously, blending share accumulation with active options strategies.
