Tudor Investment raises direct IBIT stake as options exposure falls

Tudor Investment increased its directly held position in BlackRock's iShares Bitcoin Trust after several quarters of reported selling, according to a CoinDesk account of the firm's latest regulatory filing. The update is notable because the direct ETF holding moved differently from the firm's options book, making the disclosure more nuanced than a single bullish or bearish label.

The same report said call-option exposure fell 85.2% to the equivalent of 148,000 underlying shares. Put exposure declined 1.4% to 715,000 underlying shares. Calls, puts and directly owned shares have different payoff structures, and a public holdings form does not show every hedge or transaction completed after the reporting date. The figures therefore describe disclosed positions, not a complete real-time trading strategy.

IBIT is a regulated vehicle that tracks spot Bitcoin exposure without requiring an institution to custody the asset directly. Changes in large-manager filings can help document how traditional portfolios use the product, but they should not be treated as trading instructions or proof of future demand. A larger direct stake can coexist with reduced derivatives exposure for several portfolio-management reasons.

The next useful comparison will be the firm's subsequent filing and any amendments to the current report. Until then, the verified conclusion is limited: direct IBIT ownership increased while both reported call and put exposures decreased during the covered quarter.
