When money enters a spot Bitcoin ETF, the fund must buy real Bitcoin to back the new shares (a creation); when money leaves, it sells (a redemption). Daily net flow — creations minus redemptions across all the US spot ETFs — is therefore the most direct public measurement of traditional-finance demand for the asset itself: pensions, advisors, and brokerage accounts that will never touch an exchange.
The live panel shows daily net flow per asset (BTC and ETH), the 7-day total, the cumulative flow since the ETFs launched, and total net assets under management.
What each number tells you
- Daily net flow — one day of institutional-channel demand. Noisy on its own: a single big day is often one allocator rebalancing, not a trend.
- 7-day total — smooths the noise. A week of one-sided flow says considerably more than any single print.
- Streaks — consecutive same-direction days are the strongest structural signal in this dataset; long inflow streaks marked the heaviest accumulation phases of past cycles.
- Cumulative since launch — the adoption story in one number: everything that has entered the complex, net, since day one.
- Total net assets — scale context. A $100M daily flow means something different against $5B than against $60B.
The reporting-lag trap
Flows are reported after the US market close, and most issuers' numbers settle with a T+1 lag — the figure you read in the morning describes yesterday's (or older) demand. Two consequences: never treat a flow print as breaking news the market hasn't seen, and never expect today's price to obey yesterday's flow. By the time a flow is published, price has usually already reacted to the buying or selling it represents.
Flows follow price too
It's tempting to read flows as pure cause: money in, price up. In practice causality runs both ways — rallies attract inflows and drawdowns trigger redemptions, so flows partly mirror the price action that already happened. That's why the streak and the trend of flows carry more information than any single day, and why flows are context for a market view, not a trade trigger.
Caveats
- US-listed spot ETFs only — international products and OTC demand aren't in these numbers.
- Once-a-day data: nothing intraday, and holiday/weekend gaps are normal (crypto trades every day; ETFs don't).
- Aggregated across issuers — a headline zero can hide one fund's large inflow offsetting another's outflow.
- Read in confluence: ETF flows describe the slowest, stickiest capital; the taker-flow dashboard describes the fastest. When both lean the same way over a stretch, that alignment is the interesting observation.
