Paul Tudor Jones increased his holdings of BlackRock's spot Bitcoin ETF during the second quarter while reducing his call-equivalent exposure, according to a quarterly regulatory filing tied to his firm, marking a shift toward more direct Bitcoin ETF ownership.

The disclosure appears in a quarterly filing indexed on the U.S. Securities and Exchange Commission's EDGAR system and submitted under the entity associated with Tudor Investment Corp, according to the filing's EDGAR index page. Quarterly institutional holdings filings of this kind, commonly filed as Form 13F, are due within 45 days of each quarter's end and list U.S.-listed holdings such as ETF shares as of quarter close, which means they are snapshots that arrive weeks after the fact and do not capture short positions or other hedges.

The vehicle at issue is BlackRock's iShares Bitcoin Trust (IBIT), which launched in January 2024 as part of the first wave of U.S. spot Bitcoin ETFs approved by the SEC and has since grown into the largest fund of its kind by assets under management.

What changed in Tudor's Bitcoin-linked exposure

The core change is a move between two different ways of holding Bitcoin exposure. On one side, Tudor increased its position in shares of BlackRock's Bitcoin ETF. On the other, it pared back call-equivalent exposure over the same quarter.

These are not the same instrument. ETF shares represent direct ownership of a fund that holds Bitcoin, while call-equivalent exposure is derivatives-linked and reflects the notional effect of options positions rather than outright shares.

The distinction matters because the two express a Bitcoin view in structurally different ways. Adding shares while trimming call-equivalent exposure describes a rebalancing in how the position is held, not necessarily a change in overall market direction.

Why the structure of the move is notable

Swapping derivatives-style exposure for fund shares can be read as a cleaner, more straightforward way to hold Bitcoin. Options positions carry expiries and leverage characteristics that outright ETF shares do not.

The filing does not spell out a stated motive, so the shift is best described by what it shows: a reduction in call-equivalent exposure alongside a larger holding of BlackRock's Bitcoin ETF. Any interpretation beyond that structural change is not supported by the disclosure itself.

Jones's interest in Bitcoin also predates the ETF era. In 2020 he publicly described holding a small allocation of his assets in Bitcoin as an inflation hedge, and he has continued to discuss the asset in interviews since. The Q2 filing shows that exposure now carried in part through a fund that only became available with the January 2024 spot ETF launches.

What it signals for Bitcoin ETF watchers

A high-profile hedge fund manager adjusting Bitcoin-linked exposure draws attention from ETF and crypto-market readers, particularly when the named vehicle is BlackRock's fund. The move follows other institutional activity in the same product, such as Morgan Stanley raising its BlackRock Bitcoin ETF stake.

Positioning in the fund has cut both ways this year, including cases where large holders have exited, as seen when a mystery whale paid to exit the BlackRock Bitcoin ETF. A single manager's quarterly filing is one data point, not a market-wide trend on its own.

Filings like this one offer a window into how institutional investors are choosing to express Bitcoin exposure, a theme that has run alongside the broader expansion of Bitcoin ETF access among large financial firms. The next quarterly snapshot for the period ending September 30 is scheduled to become public by mid-November under the standard filing deadline, which will show whether the shift toward direct ETF shares held.
