Definition. US Spot ETF Balances reports the most recent balances of the leading Crypto ETFs traded in the U.S., typically reflecting holdings at the end of the previous trading day (T+1). US Spot ETF Flows is the flow counterpart.

Technical. Data is taken directly from the ETF issuers. Hence, outside trading hours and in particular during the weekend, the metric may receive delayed updates only. The maximum available timestamp per ETF may differ, depending on the issuers' update frequency. 'Total' is only updated once data for all contributing ETFs is available.

Notes. Source data is publicly available information obtained directly from the respective ETF issuers.
