Paul Tudor Jones' Firm Buys Back Into BlackRock Bitcoin ETF After a Year of Selling

In brief

• Tudor Investment increased its stake in BlackRock's IBIT to 688,529 shares (~$22.9 million) as of June 30, an 18.9% jump from the prior quarter, reversing a year of selling, per its latest 13F filing.
• The firm also cut its reported IBIT call options by about 85% while keeping puts roughly flat, suggesting a move from leveraged positions toward straightforward spot exposure—though the stake remains far below its late-2024 peak of over 8 million shares.
• The buying, from a longtime Bitcoin-as-inflation-hedge advocate, lands amid renewed institutional ETF interest.

Tudor Investment, the macro hedge fund founded by billionaire Paul Tudor Jones, added to its stake in BlackRock's spot Bitcoin ETF last quarter, reversing a year-long stretch of selling.

The Connecticut firm held 688,529 shares of the iShares Bitcoin Trust, or IBIT, valued at about $22.9 million as of June 30, according to a 13F filing submitted to the Securities and Exchange Commission on Aug. 14.

That marks an 18.9% jump from the 579,083 shares it reported at the end of March, a net addition of 109,446 shares.

The increase is modest in the context of Tudor's roughly $100 billion-plus in assets, amounting to a fraction of a percent of its reported 13F holdings, and it remains far below the firm's late-2024 peak of more than 8 million IBIT shares, then worth around $427 million, which it whittled down through 2025.
