U.S. spot Bitcoin exchange-traded funds recorded $21.13 million in net inflows on Oct. 9, while Ethereum ETFs posted $56.10 million in net outflows, extending their losing streak to a ninth consecutive trading day, according to SoSoValue. Spot ETFs hold the underlying asset directly, and their daily net flows are widely tracked as a gauge of investor demand through these products.

BlackRock's IBIT led the Bitcoin inflows with $22.38 million, while Fidelity's FBTC saw $3.58 million in outflows. On the Ethereum side, BlackRock's ETHA accounted for the day's reported withdrawals.

The divergent flows came as both assets declined in price. On-chain analytics firm Santiment also flagged shifting exchange balances, with ETH moving onto trading platforms and BTC leaving them, between Oct. 4 and Oct. 8.

Bitcoin ETFs Attract Inflows as Ethereum Funds Lose Cash

According to SoSoValue data, U.S. spot Bitcoin ETFs took in $21.13 million in net inflows on Oct. 9. BlackRock's IBIT attracted $22.38 million, while Fidelity's FBTC recorded $3.58 million in outflows.

Ethereum ETFs, by contrast, posted $56.10 million in net outflows that day. BlackRock's ETHA accounted for the reported withdrawals, extending the outflow streak to nine consecutive trading days.

Santiment previously reported that spot Ethereum ETFs had recorded six straight days of outflows as of Oct. 6, while Bitcoin funds attracted capital, according to Farside data cited by the analytics firm.

Exchange Balances Show Opposite Trends for BTC and ETH

Exchange balances moved in different directions between Oct. 4 and Oct. 8. Santiment reported that ETH balances on exchanges increased by more than 100,000 ETH, nearly 2%, during that period.

Bitcoin balances, by contrast, fell by approximately 15,000 BTC over the same window. Santiment said Bitcoin was leaving exchanges while Ether was returning to them. Exchange balances are a closely followed on-chain metric because assets held on trading platforms can be sold more readily, and sustained shifts in either direction are often read by analysts as changes in holders' readiness to trade.

Prices also declined during the period. ETH fell approximately 10%, while BTC dropped around 6%, according to Santiment.

ETF Flows Remain Mixed Across Both Assets

U.S. spot Bitcoin ETFs began trading in January 2024, followed by spot Ethereum funds in July 2024. Historical ETF data from January 2024 through October 2026 shows repeated shifts between inflows and outflows.

Bitcoin funds recorded several large inflow spikes, including one near $1.35 billion in late 2024 and early 2025. However, substantial withdrawals also appeared during later periods, including an outflow approaching $1 billion around March 2025. Flows became frequent from July 2026, although recent activity remained mixed.

Ethereum ETF data likewise shows fluctuating daily flows alongside price changes. ETH climbed toward 4,500–4,800 around September 2025 before declining toward 1,500–2,000 in mid-2026. The latest chart shows a partial recovery toward 2,000–2,500, followed by renewed pressure near $2,500.

Upcoming daily flow figures from SoSoValue and Farside will show whether Ethereum's outflow streak extends past nine trading days and whether Bitcoin funds sustain their mixed, two-way activity.

The supplied data does not establish ETF flows as the sole cause of either asset's price movements.
