U.S. Spot Bitcoin ETFs Attract $606 Million in One Day, BlackRock Dominates

Spot Bitcoin exchange‑traded funds (ETFs) in the United States recorded inflows of $606 million on Thursday, marking the biggest daily net addition since May. The surge was led by BlackRock, whose fund captured about 83 % of the total flow.

BlackRock’s Share of the Inflow

BlackRock’s spot Bitcoin ETF accounted for the majority of the $606 million, indicating strong investor confidence in the firm’s product and its role in the growing U.S. Bitcoin ETF market.

Altcoin Funds Join the Trend

For the first time in the reporting period, funds focused on altcoins also reported net inflows, suggesting broader interest in cryptocurrency‑linked investment vehicles beyond Bitcoin.

Market Context

The inflow comes amid a backdrop of mixed price action across major cryptocurrencies, with Bitcoin trading around $76,984 and a 1.8 % decline on the day. Other notable price moves include Ethereum down 4.4 % to $2,412 and Binance Coin up 1.1 % to $692.98.

Implications

The sizable one‑day addition highlights continued demand for regulated crypto exposure in the United States and underscores BlackRock’s dominant position in the nascent spot Bitcoin ETF space.
