Paul Tudor Jones Increases Stake in BlackRock Bitcoin ETF

Tudor Investment Corp increased its holding in BlackRock’s iShares Bitcoin Trust (IBIT) to 688,529 shares, valued at $22.9 million as of June 30, 2026. The firm reported 579,083 IBIT shares in the prior quarter, an 18.9% increase. The position was disclosed in Tudor’s 13F filing with the Securities and Exchange Commission for the quarter ended June 30, 2026.

Tudor Investment Corp manages about $106 billion in assets, so the IBIT stake represents a small portion of the firm’s total assets. The filing continues a sequence of quarter-over-quarter additions to the IBIT holding.

Paul Tudor Jones first disclosed bitcoin exposure in a May 2020 market note titled ‘The Great Monetary Inflation,’ reporting a low single-digit allocation via bitcoin futures. Since U.S. spot bitcoin ETFs began trading in January 2024, Tudor and other institutional investors have used regulated ETFs to gain bitcoin exposure without managing private keys. In an October 2024 interview, he summarized his asset stance: “I’m long gold. I’m long bitcoin. I own zero fixed income.”

BlackRock’s IBIT held roughly 49% of total U.S. spot bitcoin ETF assets, with total assets across all U.S. spot bitcoin ETFs near $105 billion in the second quarter of 2026.

Tudor’s filing coincided with an Edelman Financial disclosure of a roughly $34 million position in a spot bitcoin ETF. Third-quarter 13F filings, due in mid-November, will show whether Tudor adjusts its IBIT position further.
