Quantitative trading firm Jane Street disclosed $990 million in U.S. spot Bitcoin ETF holdings as of June 30, according to a Securities and Exchange Commission filing, with roughly $828 million allocated to BlackRock's IBIT and the remainder split across Fidelity's FBTC and Grayscale products.
The disclosure covers one of the largest known institutional positions in Bitcoin ETFs by a single trading operation. Jane Street's holdings are shares in the ETF vehicles themselves rather than direct Bitcoin ownership, meaning the firm's exposure runs through the fund structure and custodians rather than self-hosted wallets. The filing was announced August 17, 2026, covering the second quarter period.
Jane Street's IBIT allocation of $828 million tracks with BlackRock's product dominance in institutional Bitcoin ETF adoption since its January 2024 launch. BlackRock's IBIT has accumulated roughly $20 billion in assets under management, making it the largest spot Bitcoin ETF on the market. Fidelity's FBTC, which launched the same month, holds approximately $9 billion. Grayscale's GBTC, the legacy Bitcoin trust converted to an ETF structure in January 2024, manages around $30 billion but carries higher expense ratios than the newer competitors.
Quantitative trading firms like Jane Street typically allocate to Bitcoin ETFs for transparent pricing feeds for algorithmic trading and the ability to hold positions across multiple registered investment accounts. Since the SEC approved the first U.S. spot Bitcoin ETFs in January 2024, inflows to the products have exceeded $30 billion from institutions and high-net-worth accounts.
Jane Street's $990 million Bitcoin ETF position is roughly 0.5 percent of the total assets under management across all U.S. spot Bitcoin ETFs, currently near $200 billion combined. The firm split holdings across three separate ETF providers. The IBIT allocation is $828 million of the $990 million total.
