Bitcoin ETFs Post Strongest Weekly Inflows Since October 2025

US spot Bitcoin exchange-traded fund (ETF) inflows surged last week after months of uneven flows, with investors pouring nearly $2 billion into the products amid a surge in Bitcoin’s price.

Bitcoin ETFs recorded $1.92 billion in net inflows during the week ending Friday, marking their strongest weekly performance in nearly 10 months, according to SoSoValue data.

ETF analyst Nate Geraci said Sunday that spot Ether ETFs also attracted about $700 million. He added that Bitcoin and Ether funds each posted their strongest weekly inflows since October 2025.

The renewed ETF demand came amid Bitcoin jumping more than 20% last week, briefly surging past $79,000 on Friday after starting the week near $63,000, according to CoinGecko.

The funds saw their heaviest monthly outflows in June at $4.51 billion, following $2.43 billion in withdrawals in May. August has brought $2.38 billion in net inflows through Friday, making it the strongest month for inflows so far this year.

During the last major inflow wave in October 2025, the funds attracted $3.42 billion. The October inflows preceded the Oct. 10 crypto market crash, which triggered the largest liquidation event in the industry’s history, wiping out roughly $19 billion in leveraged positions within 24 hours.

Since Oct. 6, when Bitcoin traded near $124,700, its price has plummeted roughly 38%.
