Bitcoin spot exchange-traded funds (ETFs) recorded net inflows for a ninth straight trading session, following a similar run in August. The streak was the same length, but the inflow amount exceeded the previous record.

Blockchain media outlet Decryp reported on Sept. 30, citing local time, that net inflows into bitcoin spot ETFs totalled $66.19 million on Sept. 29. Cumulative net inflows over the nine sessions from Sept. 17 to 29 reached about $3.08 billion. That topped about $3.04 billion recorded during the previous nine-session inflow streak from Aug. 17 to 27.

Markets are focusing on continued buying even as ETF inflows slow. Daily net inflows fell to $66.19 million on Sept. 29 from $999 million on Sept. 21, but the net inflow trend held. Bitcoin traded around $84,400 intraday on Sept. 30, below September's high of $87,350.

The shift in fund flows came after a U.S. Federal Reserve (Fed) rate hike. The Fed raised its benchmark rate by 25 basis points on Sept. 16 to 3.75 percent to 4 percent. Markets had already priced in the possibility of a rate hike, but risk appetite shrank quickly. Bitcoin slid to around $75,000 that week, and about $746 million flowed out of ETFs over two days.

ETF flows turned to a net inflow of $159.5 million on Sept. 17. Bitcoin regained the $80,000 level within two days. Buying then grew, with inflows rising to $999 million on Sept. 21. Cumulative weekly inflows for the week ending Sept. 25 came to $2.4 billion, the largest weekly inflow since October 2025. That also turned ETF flows back to positive on a year-to-date basis.

A bitcoin spot ETF is a product that allows investors to gain performance tied to price moves without buying bitcoin directly or keeping it in a separate wallet. It can be traded like a stock through securities firm apps, and is also used as an indicator of supply and demand from institutional and retail investors. Recent moves show inflows via ETFs continuing as bitcoin prices rise gradually.

The macro environment has yet to recover. Bitcoin's summer rebound coincided with the U.S. Treasury saying on Aug. 19 it would double the minimum size of long-term Treasury buybacks to at least $4 billion per operation. Bitcoin reclaimed $69,000 for the first time in two months that day. Gains then continued as ETF inflows strengthened, but the current price is about one-third below the record high of $126,296 set in October 2025.

This inflow streak is still short of the 13-session run recorded in June 2025. To match that record, net inflows would need to continue through Oct. 5. With daily inflows shrinking recently, attention is on whether the net inflow trend will persist.
