Key Takeaways

- • The firm simultaneously slashed its call-equivalent position on the same ETF by 85.2%, dropping from 998,000 to 148,000 shares, while put-equivalent positions remained largely flat at 715,000 shares (down 1.4%).
- • The divergent moves—increasing direct exposure while cutting call bets—signal a complex Bitcoin strategy that SEC Form 13F filings do not fully disclose, as options details including strikes, expiration dates, and premiums remain outside regulatory reporting requirements.
- • Put-equivalent positions are now valued at $23.8 million, approximately 4.8 times the call-equivalent value of $4.93 million, a significant reversal from Q1 when calls exceeded puts by a 1.4x ratio.
- • The position increase reverses a year-long period of selling activity by Paul Tudor Jones' investment firm in the Bitcoin ETF space.
Summary
Tudor Investment, the asset management firm led by veteran macro investor Paul Tudor Jones, expanded its direct exposure to Bitcoin through BlackRock's flagship iShares Bitcoin Trust ETF (IBIT) in the second quarter of 2026, according to SEC Form 13F filings released in August. The firm added 109,446 shares during the period, representing an 18.9% increase from the prior quarter's holdings of 579,083 shares. The expanded position was valued at $22.9 million at quarter-end on June 30.
However, the filing reveals a more nuanced positioning strategy than simple directional bullishness. While Tudor Investment increased its direct IBIT holdings, it simultaneously reduced its call-equivalent position by 85.2%, cutting this exposure from 998,000 shares to 148,000 shares over the same three-month period. Put-equivalent positions moved only marginally, declining 1.4% to 715,000 shares from 725,000. The put line is now valued at $23.8 million, substantially exceeding the call position's $4.93 million valuation—a stark reversal from Q1, when calls were approximately 1.4 times larger than puts.
The divergent positioning complicates any straightforward interpretation of the firm's Bitcoin strategy. SEC Form 13F instructions require options to be reported in terms of underlying share equivalents rather than premium or fair value, meaning the disclosed quantities and valuations do not capture critical information such as strike prices, expiration dates, premiums paid, or the underlying purpose of individual positions. This regulatory blind spot leaves material questions about Tudor Investment's intended directional exposure and hedge ratios unresolved by the filing alone.
The Q2 activity marks a notable shift in Tudor Investment's Bitcoin ETF posture after a sustained period of net selling throughout 2025 and early 2026. The return to accumulation of direct IBIT shares suggests renewed conviction in Bitcoin exposure, though the simultaneous reduction of leveraged call positions and elevated put exposure indicate the firm is managing portfolio risk with defined downside protection.
