Bitcoin ETFs Soar 31% as BTC Price Hits 25% Monthly Gain

US-listed spot Bitcoin exchange-traded funds (ETFs) had their best month of 2026 in August, coinciding with a 25% gain in Bitcoin's price. According to SoSoValue data, these funds attracted $3.52 billion in net inflows last month, the highest monthly total this year.

This surge marked a significant shift from July's $172 million in inflows and cut year-to-date outflows by 66%, from $5.29 billion to $1.77 billion. The funds recorded net inflows on 16 of 21 trading days in August, including nine consecutive sessions from August 17 through August 27.

Bitcoin's price rally was its strongest since November 2024, when it gained 37.29%. However, this momentum quickly gave way to a weaker start to September, as ETF flows turned negative and Bitcoin briefly fell below $77,000.
