Overview
- The June 30 filing, disclosed in mid‑August, showed Tudor Investment held 688,529 shares of BlackRock’s iShares Bitcoin Trust (IBIT), an increase of 109,446 shares from March 31.
- Tudor’s reported call‑equivalent quantity fell about 85% to 148,000 underlying‑share equivalents while its put‑equivalent count edged down to roughly 715,000.
- The filing put dollar values on those lines: direct IBIT shares at about $22.9 million, the call line at $4.93 million, and the put line at $23.8 million.
- Form 13F rules require long options to be shown as underlying‑share equivalents and do not disclose strikes, expiries or premiums, so the raw 13F rows cannot be summed to determine Tudor’s net or delta‑adjusted exposure.
- IBIT itself holds a concentrated amount of Bitcoin (about 747,000 BTC in mid‑August reporting), so ETF inflows become on‑chain purchases and the next quarter’s 13F, covering September 30, will be needed to clarify whether Tudor kept, added or trimmed exposure.
