Ark Invest’s ARKB ranks third with 43,338 BTC (~$2.88 billion). Bitwise’s BITB holds 32,105.38 BTC, Vaneck’s HODL controls 8,824.02 BTC, and Valkyrie’s BRRR oversees 7,731.50 BTC. The Invesco Galaxy ETF holds 5,937 BTC, Franklin Templeton’s EZBC carries 4,843 BTC, and Wisdomtree’s BTCW has 1,194.88 BTC. The newly launched Hashdex spot bitcoin ETF, which has just begun accumulating reserves, possesses 163.3 BTC.
Including GBTC, the 11 ETFs combined possess 835,485.71 BTC, making up 4.24% of the total circulating supply of 19.67 million BTC. Despite GBTC’s persistent outflows, the strong absorption by other funds signals growing institutional confidence in Bitcoin as a long-term asset.
