Fact
Every figure in this briefing is drawn from the site's canonical dataset as it stood on 31 July 2026.
Forecast
Any forward-looking framing in this note is interpretation, not a measured outcome, and is labelled as such.
What changed since the previous briefing
This is the earliest briefing on file, so there is no earlier note to measure it against. It records the state of the curated record as it stood on 31 July 2026.
What the series is
Each value is the market capitalisation at the close of the named calendar year, computed from the year-end price and the circulating supply at that date. Figures are rounded to the nearest million dollars, which is the precision the underlying supply and price data supports.
What it is not
The series is deliberately labelled as year-end. It is a set of annual observations and must not be read as a daily series, and the basis field on every record states this. A capitalisation computed from a year-end price is not the same as one computed from a daily close.
The record
The series runs from about one million dollars at the close of 2010 to about 1.75 trillion dollars at the close of 2025. The 2025 figure is computed from the year-end price and the circulating supply at that date, and it carries the same year-end basis as every earlier observation.
