Overview
- The quarter‑end SEC Form 13F snapshots cover positions as of June 30 and were filed in mid‑August, giving a delayed, instrument‑specific view of holdings rather than a live picture of trades.
- Two Abu Dhabi sovereign entities, Mubadala and the Abu Dhabi Investment Council, reported unchanged IBIT share counts at 14.7 million and 8.2 million respectively, showing value losses came from price moves not quarter‑end share sales.
- Tudor Investment raised direct IBIT ownership to 688,529 shares and cut its reported call‑option equivalents by about 85%, a change that increased visible share holdings while reducing disclosed long‑call exposure.
- UBS reported a more than 24‑fold jump in IBIT call‑option equivalents to roughly 1.95 million underlying‑share equivalents while modestly raising direct holdings, and Morgan Stanley added a newly reported 2.57 million‑share in its own Bitcoin trust as external ETF units fell.
- CryptoSlate’s cross‑filing analysis estimated roughly $4.89 billion of net outflows from U.S. Bitcoin ETFs in Q2 but warned that 13F rules convert options into underlying‑share equivalents and omit shorts and written options, so manager rows are partial signals not full hedge books.
