US spot Bitcoin ETFs recorded $174.6 million in net inflows on Friday, Sept. 4, 2026, a 76.1% decline from Thursday’s $730.8 million. BlackRock’s IBIT and Fidelity’s FBTC were the only two of 12 tracked funds to attract positive flows, with $117.4 million and $57.2 million, respectively. The remaining 10 funds reported zero net flows and none recorded an outflow. The data indicates a slower pace of new money entering the funds, not withdrawals from them. Nasdaq and the New York Stock Exchange were scheduled to close Monday, Sept. 7, for Labor Day, making Tuesday, Sept. 8, the next regular U.S. exchange session. Global Bitcoin trading continued during the holiday closure, while exchange-traded products remained subject to stock-market hours. The figures do not identify the investors behind the flows or establish whether a price move or payroll release caused the slowdown, and one session cannot confirm a lasting demand trend.
