Not financial advice. --- # Jane Street Expands Fidelity Bitcoin ETF Stake Eightfold as JPMorgan Buys IBIT Regulatory filings show Jane Street lifted its FBTC holdings to $509 million in the third quarter while JPMorgan Chase cut its direct spot Ether ETF exposure. ## At a glance - **What happened:** Jane Street expanded its Fidelity spot Bitcoin ETF holdings nearly eightfold to $509 million in Q3 2026 while JPMorgan increased its BlackRock IBIT stake. - **Why it matters:** The disclosures show leading institutions balancing their spot ETF provider exposure across competitors while paring back certain Ethereum fund positions. - **Who is affected:** Institutional ETF issuers, market makers, and institutional asset managers. - **Takes effect:** 2026-09-30 - **What's next:** Subsequent mandatory 13F filing windows will detail fourth-quarter balance sheet adjustments by major Wall Street desks. - **Primary source:** [Jane Street boosts Fidelity Bitcoin ETF holdings nearly 8x, trims IBIT](https://cointelegraph.com/news/jane-street-add-fidelity-bitcoin-etf-ibit-cut-q3-2026?utm_source=rss_feed&utm_medium=rss&utm_campaign=rss_partner_inbound) — cointelegraph.com ## Key points - Jane Street expanded its FBTC stake to 7.01 million shares worth $509 million while reducing its IBIT share count by 19% to 20.22 million shares in Q3 [1]. - JPMorgan raised its IBIT position to 11.41 million shares worth $540 million and lifted its Strategy stake by 36% to $131 million [1]. - JPMorgan virtually eliminated its direct ETHA position, cutting its stake from 1.17 million shares to 399 shares [1]. ## Editorial remark - **Context:** Second-quarter institutional disclosures established Jane Street as the primary institutional owner of IBIT after an aggressive 324% share boost. Third-quarter filings indicate that top tier market makers redistributed substantial spot crypto exposure across alternative issuers like Fidelity and 21Shares, even as underlying fund assets expanded. - **Impact:** Market maker and bank capital flows directly alter liquidity distributions across competing ETF products. While BlackRock retains asset supremacy with $56 billion in IBIT, Fidelity's FBTC captured hundreds of millions in fresh institutional backing from major liquidity providers. - **Watch:** Subsequent quarterly 13F filing deadlines will reveal whether institutional desks maintain elevated market maker inventory across spot crypto funds heading into the new fiscal year. Trading firm Jane Street increased its holdings in Fidelity’s spot Bitcoin ETF nearly eightfold during the third quarter of 2026, while trimming its share count in BlackRock’s equivalent fund [1]. At the time of writing, $BTC traded at $68,746, down 6.2% over the previous 24 hours amid broader market pullbacks. Jane Street closed September with 7.01 million shares of the Fidelity Wise Origin Bitcoin Fund (FBTC), up from approximately 887,000 shares at the end of June, according to regulatory filings [1]. The position reached a reported value of $509 million on Sept. 30 [1]. Meanwhile, the firm reduced its share count in BlackRock’s iShares Bitcoin Trust ETF (IBIT) by 19%, lowering its stake to 20.22 million shares from 24.88 million [1].
