04 why our data

Why our ETF flow data

One method for every fund, published every trading day.

Fund by fund, not just totals.

Every day for every fund: IBIT, FBTC, ETHA, BSOL, GDOG and 53 more.

Calculated from issuer data.

Daily flow = change in shares outstanding × NAV, from the figures each issuer publishes for its fund. One method for all 58 funds.

Published before the US open.

One issue per trading day, monitored at status.cryptoetf.today.

Every asset that has a US spot ETF.

When a new one lists, we add it: NEAR (Bitwise NRR) was tracked from its first day of trading. New crypto ETFs →
