Why did Bitcoin ETFs lose $731 million in 2 days before $21 million inflow?

US spot Bitcoin ETFs saw $731 million in withdrawals in just two days. Investors pulled out $487 million from these funds on October 7, 2026, followed by another $244 million on October 8. These were the biggest daily outflows of the week for Bitcoin ETFs.

Bitcoin ETFs attracted $21 million on October 9 after two days of heavy withdrawals. This was the first day of net inflows since October 6. It meant investors bought more ETF shares than they sold during that session, according to Yahoo Finance.

However, the $21 million inflow was much smaller than the money withdrawn earlier. The amount recovered only about 3% of the $731 million that left Bitcoin ETFs on October 7 and 8. The funds also ended the week with lower total assets than they had at the beginning.

How Bitcoin ETFs work

Spot Bitcoin ETFs allow investors to invest in Bitcoin through regular brokerage accounts. These exchange-traded funds directly hold Bitcoin and trade on stock exchanges. Investors can buy and sell ETF shares without having to purchase and hold Bitcoin themselves, according to Yahoo Finance.

ETF fund flows help show whether investors are buying or selling these funds. A net inflow means more money entered a fund than left it during a trading session. A net outflow means more money left than entered. These figures help measure demand for ETFs separately from changes in the price of Bitcoin.
