Contract brief

This market will resolve to “Yes” if Keir Starmer ceases to be the Prime Minister of the United Kingdom for any period of time between market creation and June 15, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. An announcement of Keir Starmer's resignation/removal before this market's end date will immediately resolve this market to "Yes", regardless of when the announced resignation/removal goes into effect. The resolution source for this market will be the government of the UK, however a consensus of credible reporting will also suffice.

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
