According to ChainCatcher, according to HODL15Capital monitoring, the gap between Grayscale GBTC and BlackRock IBIT's Bitcoin holdings has further narrowed, and the former is expected to be overtaken by the latter next week. According to its statistics, GBTC currently holds 289,040 BTC and IBIT holds 287,167 BTC.
It is worth mentioning that the Grayscale GBTC official website has removed the description of "the world's largest Bitcoin ETF", perhaps because it is expected that BlackRock's IBIT holdings will soon replace its position.
