FORECAST CHECK · 13 SEPTEMBER 2026

READ CAREFULLY

These are not interchangeable

Polls measure vote intention. They estimate national support during fieldwork and carry sampling and methodological uncertainty.

Seat models transform assumptions. Geography, tactical voting and local effects can produce different totals from similar polls.

Markets measure trading. Prices reflect contract wording, liquidity and participants; they are neither polls nor financial advice.
