Bitcoin ETFs have just experienced their heaviest week of outflows this year.

From November 2 to 6, U.S. spot Bitcoin ETFs recorded total net outflows of approximately $1.2817 billion, with outflows on four of the five trading days. BlackRock’s IBIT alone saw outflows of approximately $1.2095 billion, accounting for the vast majority of the week’s net outflows.

Before the week began, U.S. spot Bitcoin ETFs still had cumulative net inflows of approximately $368 million for 2026. By the end of the week, the year-to-date figure had flipped to net outflows of approximately $914.1 million. On November 9, funds that had reported their figures recorded another approximately $201 million in net outflows, marking a third consecutive trading day of continued withdrawals.

ETFs were once the market’s favorite institutional money story. Now they’re reminding the market in the most direct way: institutions may have a heavier hand, but hitting the sell button is no gentler. $BTC
