THE CALL

Will Andy Burnham formally hold the role of Prime Minister of the United Kingdom before July 18, 2026?

Kalshi was sharper on this question — by lower Brier against the same outcome.

The market-implied probability on the day we sealed our call, pinned once and never re-snapshotted. We forecast independently — the market is the benchmark, not an input.

Resolved by independent prediction-market settlement: the matched Kalshi market "Will Andy Burnham formally hold the role of Prime Minister of the United Kingdom before July 18, 2026?" settled NO. CrisisBrief's sealed forecast is graded against that same outcome.
