US Spot ETF Flows

GET https://api.glassnode.com/v1/metrics/institutions/us_spot_etf_flows_all

This metric is an estimate of the daily net flow of funds within the leading Bitcoin and Ethereum ETFs traded in the U.S., reflecting the day-to-day changes in the ETF's holdings. The calculation is based on shares outstanding and Basket Crypto Amount when this information is available; otherwise it is based on the difference between today's balance data point and the previously available balance data point in native units. Each day's native net flow is then converted into USD, leveraging the closing USD exchange rate at 16:00 New York time. It updates hourly from 00:00 to 18:00 UTC to ensure timely information on the daily reported balances. Unlike the standard convention where updates are provided only after an interval has concluded, this metric also provides preliminary data for weekly and monthly updates once daily at 15:00 UTC.
