Massive Single-Day Inflows
Spot Bitcoin exchange-traded funds in the United States recorded a combined net inflow of roughly $999 million on September 21, according to data from SoSoValue and Farside Investors. Yahoo Finance and Bitcoin Magazine reported that this represents the largest one-day capital intake for the funds since October 6, 2025. The strong influx lifted September's month-to-date tally to $1.31 billion, building on an August capital inflow of $3.52 billion. Leading the investments on Monday was BlackRock's iShares Bitcoin trust with $381.4 million, followed by the ARK 21Shares Bitcoin ETF with $289.1 million and Fidelity's Wise Origin Bitcoin Fund with $238.8 million.

Market Rally and Institutional Interest
Bitcoin's price has climbed 44% over the past month, trading around $86,000 to $86,552, following a rally that began in late August. According to Bitcoin Magazine, analysts attribute the renewed institutional interest to a cooling artificial intelligence stock rally and a U.S. Department of Treasury liquidity-support buyback announcement in August that weakened the dollar and lowered 30-year Treasury yields. CryptoQuant reported that the cryptocurrency crossed above its 365-day moving average, signaling an exit from the bear market. Bloomberg ETF analyst James Seyffart noted that the average ETF buyer is currently in profit, with the estimated ETF cost basis rising above $81,720. Despite the recent surge, Yahoo Finance noted that spot Bitcoin ETFs remain down $450 million for the entirety of 2026 due to earlier redemptions. [1] [2]
