According to SoSoValue, the net inflow of Bitcoin ETF reached US$3.52 billion in August, the highest monthly total in 2026, a significant increase from the net inflow of only US$172 million in July.

However, the strong momentum in August was quickly replaced by a weak start in September, when ETF fund flows turned negative, and Bitcoin once fell below US$77,000.
