Bitcoin ETF Inflows Turn 2026 Positive: How to Tell If the Demand Holds

US spot Bitcoin ETFs took in roughly $2.4 billion on a net basis in the week to September 25. According to The Block that is the strongest week since October 2025, and it is enough to push the 2026 year-to-date balance from negative into positive territory for the first time. Two things matter in that for you as an investor in Germany: the number shows where demand is currently coming from, and it changes nothing about the fact that you cannot access these particular funds. This article works through the week, sets out where the various tallies diverge, and then goes through the points you can check yourself on buying route, holding period and custody.

The price itself has stayed strikingly calm. Bitcoin traded at $83,953, or 73,701 euros, on September 26 at 20:53 UTC, up 0.04 percent over 24 hours (CoinGecko, own query). A record week in fund inflows and a price that barely moves: that combination is the real finding of this week, and it deserves a closer look than the headline.

$2.4 Billion in One Week: What the ETF Inflow Numbers to September 25 Show

A net inflow is the difference between newly created and redeemed fund shares on a trading day, converted into dollars. When that number rises, the fund had to buy Bitcoin the same day; when it drops below zero, it has to sell. That is precisely why market watchers look at the series and not at a single day.
