U.S. spot Bitcoin exchange-traded funds took in $66.19 million on Tuesday, Sept. 29, their ninth consecutive session of net inflows — sessions in which money moving into the funds exceeded money moving out — according to Decrypt's Bitcoin ETF tracker. Bitcoin is grinding higher, and the ETF buyers keep showing up.

The asset changed hands near $84,400 on Wednesday, up roughly 1% on the day and recovering Monday's losses, though it remains below its September high near $87,350. Daily inflows have also cooled, shrinking from $999 million on Sept. 21 to roughly $66 million.

The current run began on Sept. 17 and has drawn about $3.08 billion, based on Decrypt data. That edges past the roughly $3.04 billion pulled in during August's nine-day streak, which ran from Aug. 17 to Aug. 27. The two streaks tie on length at nine sessions; the current one wins on dollars, by about $33 million. Hardly a landslide, but notable nonetheless, considering the August rally is widely considered to have pulled Bitcoin out of the bear market.

Bitcoin ETFs allow investors to gain exposure to the asset without buying BTC directly from a crypto exchange or holding it in a wallet. The funds hold bitcoin on investors' behalf, track its price, and trade like stocks on brokerage apps. They have been widely popular since first launching two and a half years ago, and market observers look to their flows — both in and out — as a reliable sentiment indicator.

That sentiment has shifted quite dramatically in recent weeks.

On Sept. 16, the Federal Reserve raised rates by 25 basis points (0.25 percentage points) to 3.75%–4%, its first hike since 2023. Traders had put the odds of a hike at nearly 93% beforehand. Rising interest rates spook investors in risk assets such as Bitcoin, as "cheap money" becomes more scarce.

Bitcoin slid to about $75,000 that week, and the ETFs had just bled roughly $746 million over two days. Flows then flipped on Sept. 17 with $159.5 million in net inflows, and Bitcoin was back above $80,000 within two days.

The money arrived fast after that. Inflows hit $999 million on Sept. 21, and the week ending Sept. 25 drew $2.4 billion, the biggest weekly haul since October 2025. That pushed the funds back into positive territory for 2026, meaning money added to the funds this year now outweighs money withdrawn.

The macro backdrop has not gotten easier. Bitcoin's summer rebound traces to Aug. 19, when the U.S. Treasury said it would double its longer-dated bond buybacks to at least $4 billion per operation. Bitcoin reached $69,000 that day, its first time at that level in two months. The asset now trades about a third below its October 2025 record of $126,296.

The current run still trails the 13 straight days from June 2025. The record chase now turns on each daily flow report: matching that mark would take net inflows through Monday, Oct. 5.
