Track daily net flows into US spot Bitcoin ETFs by issuer — BlackRock IBIT, Fidelity FBTC, Grayscale GBTC, Ark ARKB and the rest — plus cumulative flows and the institutional demand picture for BTC.
Spot ETF issuers buy and sell real BTC to back creations and redemptions, so sustained net inflows are structural demand — and outflow streaks have preceded most local tops since launch.
IBIT and FBTC dominate inflows while GBTC bleeds from its legacy fee; the per-issuer table shows where the marginal dollar is going each session, plus cumulative totals since inception.
