Why this matters:
This 21% probability represents the likelihood of military engagement between China and Taiwan before year-end 2026. The estimate reflects significant disagreement between markets (Kalshi at 32%, Polymarket at 17%), suggesting genuine analytical uncertainty. Recent geopolitical tensions, cross-strait rhetoric, and military posturing by both sides inform the upside case, while the status quo of deterrence and economic interdependence supports the lower probability. The resolution will depend on escalation triggers—whether accidental incidents, political transitions, or external interventions tip calculations toward conflict. Near-term catalysts include military exercises, leadership statements on cross-strait policy, and any unplanned encounters between military forces that could spiral beyond control. The roughly 8-month window remaining makes any assessment sensitive to developments that shift perceived red lines or calculations of military advantage.

Key factors:
- Current PLA military exercises near Taiwan and their stated frequency, scope, and stated purpose indicate baseline tension levels and readiness posture
- Statements by Chinese and Taiwanese leadership on red lines, deterrence thresholds, and unification timelines directly affect market participants' assessment of intent
- U.S. military positioning in the region, official statements on Taiwan defense commitments, and weapons delivery schedules influence perceived constraints on Chinese action
- Accidental military encounters or incidents (ship collisions, aircraft proximity events) have historically driven short-term probability spikes and establish precedent for escalation management
- Economic data, trade disruption signals, and investor capital flows to Taiwan and China may reflect private-sector assessment of conflict risk and affect market pricing

## 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.
