US Bitcoin ETFs End 9-Day Streak; Weekly Total Provisional

Published October 4, 2026, 09:05 UTC. Data as of October 4, 2026, 08:55 UTC.

US spot Bitcoin exchange-traded funds (ETFs) ended a nine-day, $3.1 billion inflow run on September 30, then recovered some ground. The weekly totals below are provisional and likely understated, because one large fund's Friday figure was still missing. Flows into Ethereum funds turned negative.

The streak ends

According to The Block, the funds' nine-day, $3.1 billion net inflow streak ended on Wednesday, September 30, with $148.7 million in combined net outflows. Key details from that report:

• BlackRock's IBIT, usually the dominant fund, ended its own nine-day, $1.6 billion inflow run with $9.5 million leaving.
• Fidelity's FBTC led the day's outflows with $125.6 million, followed by Bitwise's BITB with $13.6 million. The remaining funds recorded zero flows.
• Per The Block's tracker, the funds have attracted over $57 billion since their January 2024 debut, with $970 million so far this year and over $100 billion in assets.
• Bloomberg ETF analyst James Seyffart noted the funds remain about $5 billion short of their cumulative-flow peak from October 10 last year.

The weekly picture is provisional

Weekly figures from Farside Investors show US spot Bitcoin ETFs took in a provisional net $82.9 million for September 28 to October 2, versus about $2.39 billion the week before. Farside's table still showed no entry for BlackRock's IBIT for Friday, October 2, as of October 4, so the weekly total is likely to change and is likely understated.

By day, Farside's table shows net inflows of $31.0 million on Monday and $66.2 million on Tuesday, the $148.7 million outflow on Wednesday, then inflows of $102.7 million on Thursday and $31.7 million on Friday, excluding IBIT. Secondary coverage by Cryptonews.net, which cites Farside, also reported provisional Ethereum ETF outflows of $118 million for the week and $800,000 in net inflows for Solana ETFs. Treat all weekly totals as provisional until the data is complete.

Price and macro backdrop

The Block reported that Bitcoin traded around $84,000 on Wednesday, after a softer-than-expected reading of the Federal Reserve's preferred inflation gauge (core PCE rose 0.2% month on month) reduced expectations of an October rate hike. Bitcoin finished September up 6.4%, the report said.

The Fed's September meeting is the backdrop. On September 16, the Federal Open Market Committee voted 12-0 to raise its target range for the federal funds rate by a quarter point to 3.75% to 4%, saying inflation "remains elevated." The Block quoted Ma, head of investment strategy at the Arbitrum Foundation, saying a similar September CPI reading would ease pressure for an October hike. He is a crypto-foundation executive, not a Fed official, and we do not treat his comment as a forecast.

How to read the numbers

ETF flows are one indicator of demand among many. Daily figures can reverse quickly, as this week showed, and provisional data can be revised. A single week does not establish a trend. For a primer on how these funds work, see What Is a Spot Bitcoin ETF?
