What are institutions doing?
US spot Bitcoin ETFs launched in 2024 — for the first time, large, regulated buyers can hold Bitcoin through a normal brokerage. This is the structural demand that didn't exist in 2012, 2016 or 2020. Here is what it's doing, day by day.
US spot Bitcoin ETFs saw a net inflow of $216.70M on 2026-08-31, a 1-day inflow streak, bringing demand over 7 trading days to +$1.45B.
Institutional demand looks strong — net inflows over the past 7 trading days.
