Daily net inflows and outflows across every US-listed spot Bitcoin ETF, in US$ millions. Sustained inflow streaks mark institutional accumulation; persistent outflows have historically aligned with corrective phases.
Spot Bitcoin ETFs hold real BTC on behalf of shareholders. When more money enters the funds than leaves, issuers must buy Bitcoin to back the new shares; when redemptions dominate, they sell. The daily net flow therefore measures the marginal institutional bid or offer hitting the spot market, independent of what leveraged traders are doing on derivatives venues.
Flows are reported per issuer after each US trading day. BlackRock's IBIT and Fidelity's FBTC dominate the complex, while Grayscale's GBTC converted from a closed-end trust and has mostly bled assets since launch. Watching the total, the leader's share, and streaks of same-sign days gives a cleaner read on institutional demand than any single day's print.
The cumulative line sums every daily net flow since the ETFs launched in January 2024; its slope shows whether institutional demand is compounding or stalling. The daily bars isolate individual prints: green bars are net inflow days, red bars are net outflow days. One quiet day means little on its own, so focus on multi-day streaks rather than single prints.
The per-fund table breaks down the most recent trading days by issuer, so you can see whether a big total was broad-based or carried by a single fund. Concentrated inflows led by one issuer are more fragile than demand spread across several.
