Tracks the leading outcome in a winner-take-all prediction market set with 4 outcomes.

Why this matters:
This probability reflects market expectations that the U.S. State Department will issue a Level 4 "Do Not Travel" advisory for Taiwan before January 1, 2028—roughly 16 months away. Level 4 warnings are typically reserved for countries experiencing active conflict, terrorism, or severe civil unrest, making one for Taiwan a significant escalation signal. The current 40% probability suggests traders view material deterioration in cross-strait stability as plausible but not imminent. Factors driving this estimate include recent military activities in the Taiwan Strait, geopolitical tension, and the track record of State Department advisory changes during periods of heightened diplomatic friction. The divergence between the 8% probability for a 2027 warning and 40% for 2030 suggests traders expect any major escalation would unfold over time rather than suddenly. Key near-term catalysts include Taiwan election outcomes, China military exercises, and U.S.–China diplomatic developments.

Key factors:
- Current State Department advisory for Taiwan is Level 2 (Exercise Increased Caution); a Level 4 represents multiple advisory-level escalations within 16 months
- Military incidents in the Taiwan Strait or major Chinese military exercises with explicit territorial claims would be primary triggers for advisory upgrades
- U.S.–China diplomatic climate and Taiwan's domestic political events directly influence State Department threat assessments
- The 8% vs. 40% probability spread across contract windows indicates markets expect gradual escalation risk rather than sudden crisis
- Historical precedent shows Level 4 warnings follow specific triggering events (active conflict, civil war declarations, or terrorism campaigns), not routine geopolitical tension

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
