A recent sale of BlackRock’s iShares Bitcoin Trust (IBIT) shares, totaling $1.26 billion, has been interpreted as a rapid exit by a large investor rather than an unwinding of a common hedge-fund trading strategy. The transaction, which took place on May 26, involved 29.21 million shares sold at $43.16 each, representing a 2.3% discount from the market price of $44.17, resulting in approximately $29.5 million in execution costs. NYDIG analyzed the sale and dismissed the theory that it was related to a basis trade, noting the lack of significant activity in CME bitcoin futures during the sale. This sale aligns with a trend of persistent outflows from U.S. spot bitcoin ETFs, which have seen total assets decrease from $107.75 billion to $94.17 billion between May 14 and May 29. Despite the significant redemptions, NYDIG pointed out that identifying the seller remains challenging, as the position exceeded the reported holdings of all known IBIT investors. This transaction highlights the urgency of the seller in exiting a bitcoin-linked position amidst a declining market.
