Bitcoin’s 9‑day ETF inflow streak snaps just as ‘Uptober’ kicks off

The powerful wave of money that had been pouring into US spot bitcoin ETFs has finally taken a breather. Data compiled by market researchers show that on the final trading day of September, the suite of US‑listed spot bitcoin funds saw around $148.7 million in net outflows, snapping a nine‑session streak that had attracted roughly $3.1 billion in fresh capital. BlackRock’s flagship IBIT fund, which had been racking up its own nine‑day inflow run of about $1.6 billion, also flipped to modest net redemptions of roughly $9.5 million.

Despite the cooling in ETF demand, bitcoin’s spot price has remained resilient. Around October 1, the token was trading in the mid‑$84,000s, only a few percent below recent highs, and year‑to‑date ETF flows have just recently turned positive after spending much of 2026 in the red. That backdrop supports the idea that institutional interest in bitcoin as an investable asset class is still building, even as short‑term flows wobble.

The bigger question is whether ETFs can keep attracting assets in a world where US 10‑year Treasury yields hover above 5%. October has historically been kind to bitcoin—traders dub the month “Uptober” because the coin has finished higher in 10 of the past 13 years—but this time the tailwind of seasonal optimism is colliding with the headwind of high real yields and lingering Fed hike risks. If ETF inflows fail to re‑accelerate, the drying up of that marginal buyer could cap upside, making US rate moves and daily flow data key indicators for crypto investors in the weeks ahead.
