Analysis

This probability represents the chance that China conducts a military invasion of Taiwan within the next 20 months. The 17% figure suggests markets view an invasion as unlikely but not negligible. Military escalation risks, geopolitical tensions, and cross-strait stability are the primary drivers of this probability. The current level reflects a period of relative calm compared to 2024-2025, though structural factors including Taiwan's strategic importance and military modernization efforts continue to shape assessments. Key catalysts that could shift this probability include changes in U.S.-China relations, Taiwan's defense capabilities, or any military incidents in the Taiwan Strait. No single scheduled event determines resolution, but significant policy shifts or military posturing by either side would likely move markets substantially.

  • U.S. military commitment to Taiwan's defense and the current state of U.S.-China diplomatic relations
  • Taiwan's defensive military capabilities and the timeline for completing weapons systems deliveries
  • Recent military exercises or incidents in the Taiwan Strait and frequency of Chinese military activity near Taiwan
  • China's domestic economic conditions and military readiness compared to 2024-2025 assessments
  • Official statements from Chinese, American, and Taiwanese leadership regarding military intentions or deterrence strategies

Lateral coverage

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.
