Tudor Investment Corporation added to its iShares Bitcoin Trust (IBIT) stake in the second quarter, snapping four straight quarters of selling. The firm, founded by Paul Tudor Jones, held 688,529 IBIT shares as of June 30. That is up 109,446 shares from 579,083 at the end of March, an 18.9% increase, per a 13F filing submitted August 15. The position was valued at $22.9 million on the filing date, CoinDesk reported, and now sits around $24.5 million. Still well off the highs: Tudor’s late-2024 peak was 8.05 million shares, worth $427 million at the time. The current holding is 91.4% below that mark.
Options told a separate story. Call options tied to 148,000 underlying IBIT shares dropped 85.2% from 998,000 in March. Puts dipped 1.4% to 715,000 underlying shares from 725,000. Strike prices and expiration dates were not disclosed, so the options do not provide a clean directional signal. The filings cover the quarter ending June 30, 2026, and were submitted Friday.
The pattern runs deeper. Tudor first disclosed 869,565 IBIT shares in mid-2024 and built to 8.05 million shares by year-end as bitcoin ran from roughly $60,000 to $92,000. Every quarter of 2025 brought a cut. The firm finished December with 576,523 shares, trimming even as bitcoin pushed to an all-time high of $124,000 in the second and third quarters of 2025, per CoinDesk. In April 2026, Tudor Jones called bitcoin the “best inflation hedge,” citing its fixed supply as an advantage over gold. Today the IBIT position accounts for 0.03% of Tudor’s $71.9 billion portfolio.
Other institutions are building exposure on their own timelines. Edelman Financial Engines reported a $34 million position in spot bitcoin exchange-traded funds, split between BlackRock’s IBIT and Grayscale’s GBTC, according to Bitcoin Magazine, citing an SEC filing. That exceeds the firm’s $25 million Amazon holding. Edelman manages $326 billion in assets.
Ric Edelman, the firm’s founder, has pushed for bitcoin ETFs since 2019. That predates the U.S. Securities and Exchange Commission’s approval of spot products in January 2024. He also founded the Digital Assets Council of Financial Professionals, which trains financial advisors on crypto and blockchain.
Two Abu Dhabi sovereign wealth funds held firm. Mubadala Investment Company disclosed a $490 million IBIT stake in a Friday regulatory filing. It is the second-largest single holding across Mubadala’s 13F portfolio, Bitcoin Magazine reported. The Abu Dhabi Investment Council filed Thursday, showing a $273.6 million IBIT position that ranks as the largest in its portfolio. Combined: $763.7 million in the BlackRock ETF. Neither position changed from the prior quarter. The filings described bitcoin as “the most important asset” held by both funds, according to Bitcoin Magazine.
BlackRock’s IBIT carries $47.3 billion in assets under management. Earlier in 2026, Arkham Intelligence attributed roughly 6,782 bitcoin, then worth about $453.6 million, to wallets linked to the UAE’s Royal Group. Those holdings stem primarily from domestic mining, not the law enforcement seizures that account for most U.S. government bitcoin.
What the filings do not say: whether Tudor’s options reduction reflects hedging or de-risking, and what prompted Edelman’s ETF allocation. The Abu Dhabi funds gave no rationale for holding steady. Bitcoin’s spot price has cooled in August. The disclosures show large allocators holding the line regardless.
