| 2026-08-10 | $72,130,000,000 | First reading since 23 July, when $72.9bn was recorded. The rendered field is written by a script, but the figure is in the served page: the in-circulation element carries it, and the section's stated as-of is 10 August. |
| 2026-08-13 | $71,850,000,000 | Read from the data-point attribute of the usdc-in-circulation span, under the page's own as-of of 13 August, and down from 72.13 on 10 August. Reserve components in the adjacent script sum to 72.57, the expected relationship to circulation. |
Refresh
This series has no endpoint reachable from the page, so the figure shows the value as of the last build. It is not labelled live and the timestamp is the build timestamp. Cadence: monthly, two observations per report.
Treated as stale after 90 days without a new observation. Past that point the figure keeps the last verified number and carries a badge; it does not hide it and does not substitute an estimate.
Scope
Each report gives the figure at two dates in the month and both are recorded here, so the series is monthly in publication and twice-monthly in observation. It excludes EURC and excludes Circle's tokenised money market fund USYC. Being a par figure rather than a market capitalisation it does not match third-party trackers, which put USDC at $74.33bn on 25 July 2026 against Circle's last examined figure of $75.89bn for 29 May 2026.
Observations
Every observation held for this series, in the order the source published them, exactly as published by Circle.
