NEW YORK — The total assets under management across all US-listed Bitcoin spot exchange-traded funds have surpassed $100 billion for the first time, a milestone that would have seemed fantastical when the SEC reluctantly approved the first batch of Bitcoin ETFs in January 2024 after a decade of rejections. BlackRock's iShares Bitcoin Trust (IBIT) alone now holds $52 billion in assets, making it one of the most successful ETF launches in history and effectively transforming the world's largest asset manager into one of the world's largest Bitcoin holders.

The $100 billion figure represents only US spot products and excludes futures-based ETFs, Canadian and European crypto products, and direct holdings. When all crypto investment products are combined — including the newer Ethereum spot ETFs, which have gathered $35 billion — the total reaches approximately $160 billion. That is roughly 4% of the total crypto market capitalization, suggesting institutional allocation remains in its early stages.

"The psychological barrier has been broken," said Larry Fink, BlackRock's chairman and CEO, who famously called Bitcoin "an index of money laundering" in 2017 before becoming one of its most influential advocates. "When pensions, endowments, and sovereign wealth funds are allocating 2-5% of their portfolios to Bitcoin as digital gold, that's no longer a speculative bet — that's a strategic asset allocation decision." The inflows have been remarkably steady, averaging roughly $250 million per trading day across all spot products, and have come from a broadening base of investors including state pension funds, corporate treasuries, and high-net-worth individuals. The next frontier: options on spot Bitcoin ETFs, which the SEC approved in late 2025, and which have already amassed open interest exceeding $30 billion.
