Jane Street Group expanded its spot Bitcoin exchange-traded fund exposure by $630 million in the second quarter of 2026, bringing total reported holdings to $1.06 billion, according to its latest 13F-HR filing with the U.S. Securities and Exchange Commission.
The increase reverses a prior reduction in the first quarter, when the firm reportedly cut its Bitcoin ETF position by 71%. The latest filing captures positions as of the end of June and does not specify which funds were purchased, though major products such as BlackRock’s iShares Bitcoin Trust and Fidelity’s Wise Origin Bitcoin Fund are seen as likely candidates. Jane Street’s crypto-linked activity has also included strategic investments in Bitcoin miners and a previously disclosed position related to an XRP ETF.
The disclosure highlights still-mixed institutional behavior. Graham Capital cut its Bitcoin ETF position by 75% during the same period, while UBS raised its BlackRock Bitcoin ETF stake toward $90 million. Analysts view Jane Street’s move as a sign that regulated Bitcoin exposure continues to gain traction among traditional financial institutions, though 13F snapshots reflect a point-in-time allocation rather than a direct price signal. The filing does not include a fund-by-fund breakdown or commentary on the firm’s current positioning.
