Market context
A military invasion of Taiwan by the People's Republic of China would represent a fundamental shift in East Asian geopolitics and the post-Cold War security order. The resolution criteria require an offensive intended to establish control over inhabited territory administered by the Republic of China, with confirmation sourced from official statements by China, Taiwan, the UN, or permanent Security Council members, supplemented by credible reporting consensus. The 7% implied probability reflects market assessment that such an event remains unlikely within the next two years, despite elevated cross-strait tensions and military modernisation on both sides.
Historical precedent offers limited direct comparison. The 1950 Korean invasion occurred amid Cold War uncertainty and perceived Western disengagement; the 1982 Falkland Islands conflict involved a regional power miscalculating British resolve. Taiwan's case differs materially: US security commitments, Taiwan's defensive fortifications, and China's economic interdependencies create structural deterrents absent in those cases. The 1996 Taiwan Strait crisis, when China conducted missile tests near Taiwan, resulted in no invasion despite significant provocation. Traders should note that invasion probability correlates inversely with China's economic growth trajectory and Taiwan's defensive capabilities—both relatively stable through 2026.
Key catalysts include Taiwan's January 2028 presidential election cycle (affecting political messaging now), US policy shifts following the November 2024 election, and any major cross-strait military incidents. The Financial Times and Reuters regularly report on PLA exercises and Taiwan defence procurement. Regulatory accessibility varies: German GlüStV permits unlicensed trading up to €1,500 per market; US CFTC oversight applies to US persons regardless of no-KYC thresholds; UK users face FCA restrictions on prediction market access. Traders should verify their jurisdiction's applicable framework before positioning.
Methodology
We track Will China invade Taiwan by end of 2026? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
