Bloomberg ETF analyst Eric Balchunas said institutional ownership of BlackRock's IBIT remained notable even after a 50% pullback, with about 1,500 entities still appearing in 13F filings (quarterly U.S. holdings reports for large managers). In a post on X, he singled out Paul Tudor Jones, a UAE sovereign wealth fund, Harvard, Dartmouth and a Texas pension fund as especially worth watching. By contrast, he said IBIT purchases by JPM, GS, Jane and Citadel were less meaningful, suggesting those positions may be more routine trading or market-making activity than a directional endorsement.
