Bitcoin ETFs Pull In Record $2.39B: Is Demand Behind the Surge?

U.S. spot Bitcoin ETFs drew in a record $2.39 billion this week, the largest weekly total of 2026.

The funds traded on the stock market like ordinary shares and held real Bitcoin for investors.

However, daily flow data and on-chain research suggest thinner buying than the weekly record implies.

Bitcoin's price jumped 6.7% on September 21, pushing out $262 million in bets against it within an hour, prompting traders to buy.

The mood shifted on September 23 with S&P Global's business survey showing the fastest U.S. growth since July 2021 and the 10-year Treasury yield rising above 5%, causing Bitcoin to fall below $84,000.

Despite this, other data suggests demand remains active. Between September 22 and 24, about $2.52 billion in net BTC left major exchanges, typically a sign of coins moving into long-term storage.

River, a Bitcoin financial services firm, notes that large holders are adding to their wallets, with those holding 100-1,000 BTC buying 113,950 BTC since July 15.
