Bitcoin (BTC) Defies October Trend as ETFs Pull In $241M

Bitcoin defies its weak early-October trend as U.S. spot BTC ETFs record $241.09 million in weekly inflows.

Bitcoin has opened October on firmer ground than its historical pattern would suggest, while U.S. spot Bitcoin ETFs pulled in $241.09 million over the week ending Oct. 2.

CryptoQuant said the first three days of October have typically been Bitcoin’s weakest three-day stretch of the month, with an average loss of 0.66%.That pattern has not played out the same way in 2026. 

CryptoQuant noted that Bitcoin held up better through the opening three days of the month, leaving BTC ahead of its usual early-October performance.

ETF flows added another layer to the market picture. Hupzy of Spot On Chain said spot Bitcoin ETFs attracted about $241 million during the week, extending their inflow streak to three consecutive weeks, while Ethereum funds recorded net withdrawals.

Bitcoin ETFs Absorb About 2,850 BTC

Crypto Patel reported that U.S. spot Bitcoin ETFs bought roughly 2,850 BTC between Sept. 28 and Oct. 2. Based on his calculation, that amount was equal to around six days of newly mined Bitcoin supply.

So far in 2026, Bitcoin has outperformed that seasonal average. The comparison doesn’t indicate where BTC will trade later in the month, but it does show that the usual early-October weakness hasn’t appeared to the same extent.

The weekly ETF figures also showed a clear split between Bitcoin and Ethereum. Bitcoin products recorded $241.09 million in inflows, while Ethereum funds posted $138.02 million in outflows, according to data shared by Hupzy and Crypto Patel.
