US spot Bitcoin ETFs now manage approximately $102.5 billion in assets, representing about 6.29% of the total Bitcoin supply. Since their launch in January 2024, these funds have accumulated between 1.27 million and 1.32 million BTC, which are held in cold storage and removed from active circulation.
BlackRock’s iShares Bitcoin Trust (IBIT) holds an estimated 693,000 to 786,000 BTC, accounting for over 60% of total Bitcoin ETF assets. The fund has attracted more than $60 billion in cumulative inflows since its inception, while total net inflows across all US spot Bitcoin ETFs stand at approximately $55 billion.
Reaching a 10% ownership threshold of the total Bitcoin supply would require an additional $60.5 billion in ETF assets, assuming current market valuations. With Bitcoin’s total market capitalization estimated at roughly $1.63 trillion, institutional participation has grown significantly since the SEC began approving spot ETFs in 2024.
The 19.7 million BTC mined to date include millions of coins that are likely lost or dormant. As ETFs do not lend or stake their holdings, the removal of additional supply from the market is expected to further compress liquid availability amid rising demand from institutional investors and corporate treasuries.
