BlackRock’s IBIT and ProShares’ BITO became the first bitcoin {{BTC}} exchange-traded funds (ETF) to cross Grayscale’s GBTC trading volume on Thursday.
IBIT ended Thursday with $306 million in trades placed, while BITO traded $298 million. GBTC saw a relatively lower $291 million in trades, data from multiple sources show.
Thursday was also the first time daily ETF volumes were below $1 billion, Bloomberg Intelligence analyst James Seyffart said on X. These figures did not include after-hours trading.
Grayscale has led trading volumes among all bitcoin ETFs since their listing in early January. Most of these volumes have contributed to selling pressure in the past few weeks as GBTC investors took profits and shifted to other providers, some banks have previously stated.
