Contract brief

This market will resolve to "Yes" if the United States formally initiates a withdrawal from NATO or provides an official notice of denunciation to NATO by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A notice of denunciation refers to the submission of a notice of withdrawal as per Article 13 of the North Atlantic Treaty. Any action meeting these criteria will qualify for a “Yes” resolution regardless of if its implementation is immediately halted or delayed by judicial or other actions. The U.S.'s exit from NATO’s integrated military command structure will not be sufficient to resolve this market to "Yes". The resolution source will be official information from the US government and NATO, however a consensus of credible reporting may also be used.

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.
