Billionaire hedge fund manager Paul Tudor Jones’ Tudor Investment Corp increased its stake in Blackrock’s spot Bitcoin exchange-traded fund (ETF) to $22.9 million, according to a newly filed 13F.
Key Takeaways
Tudor Investment Corp held 688,529 IBIT shares worth $22.9 million as of June 30, 2026.The position grew 18.9% from 579,083 shares reported the prior quarter.The $106 billion firm’s filing lands the same week as Edelman Financial’s $34 million Bitcoin ETF disclosure.The steady build-out places Jones among a widening group of traditional asset managers using spot Bitcoin ETFs, rather than direct custody, to gain exposure to the asset. Tudor Investment Corp manages roughly $106 billion in assets, meaning the IBIT position remains a small sliver of the fund’s total book even after the latest addition.
From Inflation Hedge to ETF Buyer“I’m long gold. I’m long bitcoin. I own zero fixed income.”
That long-standing thesis has increasingly translated into ETF ownership since spot Bitcoin funds launched in the United States in January 2024, giving hedge funds a way to hold bitcoin exposure inside existing custody and compliance infrastructure instead of managing private keys directly.
Five years later, that early futures position has evolved into a direct, growing stake in a regulated spot ETF, tracking both bitcoin’s move into mainstream portfolios and Jones’ own shift toward holding it through conventional fund structures.
IBIT remains the dominant vehicle for institutional players, with Blackrock’s fund commanding roughly 49% of total U.S. spot Bitcoin ETF assets, with total assets across all U.S. spot Bitcoin ETFs holding near $105 billion as of the second quarter.
For a fund the size of Tudor Investment Corp, a $22.9 million position is quite clearly not a bet-the-firm move; however, it is quite indicative of where market sentiment seems to be shifting. To this point, Jones’ consistent quarter-over-quarter growth signals that his bitcoin allocation has shifted from a symbolic gesture toward a standing line item in the portfolio.
That being said, whether that pace continues will become clearer when third-quarter 13F filings are due in mid-November, giving the market its next look at how Wall Street’s most prominent macro investor is sizing his BTC convictions.
