US spot Bitcoin-traded funds (ETFs) flipped back to net inflows on Thursday, the first trading day of October, handing the month — popularly dubbed “Uptober” by crypto traders in reference to Bitcoin’s historically strong October performance — a positive start after the funds’ strongest quarter of 2026. Whether October lives up to its nickname will be tracked in the daily flow data over the sessions ahead.

Bitcoin ETFs attracted $102.7 million in net inflows on Thursday, a sharp reversal from Wednesday’s $148.7 million in net outflows, according to SoSoValue data. Their combined net assets rose to $109.3 billion, while cumulative net inflows reached $57.6 billion. Net flows — the difference between creations and redemptions across the funds on a given day — are a closely followed gauge of demand for the products.

Thursday’s results built on a robust third quarter, in which US spot Bitcoin ETFs took in $6.34 billion in net inflows, including $2.65 billion in September alone. Bitcoin’s price rose 42.71% over the quarter. The products, which began trading on US exchanges in January 2024 following regulatory approval, have since become a major channel for institutional exposure to the leading cryptocurrency.

At the time of publication, Bitcoin was changing hands at $85,900, up 2.1% over the past 24 hours, according to CoinGecko data. Alternative.me’s Crypto Fear & Greed Index, a widely watched sentiment gauge, slipped to 72 from 74 a day earlier, remaining in “Greed” territory. The index runs on a scale from 0, signaling “Extreme Fear,” to 100, signaling “Extreme Greed.”

The picture was less upbeat for Ether products. US spot Ether ETFs recorded $55.4 million in net outflows on Thursday, according to SoSoValue, marking a third consecutive trading day of net outflows. The Ether funds have shed roughly $118 million across the three sessions. Ether is the second-largest cryptocurrency by market capitalization. Those funds followed the Bitcoin products onto US exchanges in July 2024.

Flows across altcoin ETFs were mixed. Solana ETFs posted around $6 million in net outflows on Thursday, extending their outflow streak to a second consecutive session, while XRP ETFs attracted $4 million in net inflows. Both rank among the newest additions to the US crypto ETF lineup, where daily flow prints offer a public read on demand beyond the two largest cryptocurrencies.
