Bitcoin ETFs Soar to Best Month of 2026 Amid 25% Gains for BTC
US-listed spot Bitcoin exchange-traded funds (ETFs) saw their best month in 2026, mirroring the biggest monthly gain for Bitcoin since November 2024. In August, BTC gained about 25%, its strongest performance of that kind since a 37.29% rally last November.
The funds attracted $3.52 billion in net inflows during August, their highest total this year and a significant increase from July's $172 million. The surge brought year-to-date outflows down by 66% to $1.77B.
Bitcoin ETFs recorded net inflows on 16 of 21 trading days in August, including nine consecutive sessions from Aug. 17 through Aug. 27. Total net assets rose about 31%, reaching $99.61 billion at the end of August from $76.29 billion in July.
However, September started with a decline, as ETF flows turned negative and Bitcoin briefly fell below $77,000 on Tuesday.
