The €18.8 trillion figure refers to the European Union (EU-27), not the broader European continent (which would include the UK, Switzerland, Norway and others and be considerably higher).
The figure corresponds to 2025 data, the most recent full-year reference period available before the session date of 2026-09-14.
The claim's accompanying context ('global GDP is EUR 104 trillion') is a separate assertion and was not the subject of this verification; the EU figure was checked in isolation.
