Will China invade Taiwan by December 31, 2027?

Platform comparison

Market context

A military invasion of Taiwan by China would represent one of the most consequential geopolitical events in decades. This market asks whether such an offensive—aimed at seizing control of territory administered by the Republic of China—occurs within the next three years. When you buy a YES share, you profit if China initiates a military campaign to take any inhabited portion of Taiwan; a NO share profits if no such invasion occurs by year-end 2027. The 16% implied probability reflects current market sentiment that such an event remains unlikely but non-negligible.

Historical precedent offers limited direct parallels. The last major cross-strait military confrontation was the 1995–96 Taiwan Strait Crisis, when China conducted missile tests and exercises but stopped short of invasion. Since then, military asymmetries have shifted dramatically in China's favour, whilst Taiwan's defensive capabilities and international support have also strengthened. The absence of invasion despite decades of rising Chinese military capacity suggests structural deterrents—economic interdependence, US security commitments, and the costs of amphibious assault—remain operative. However, precedent from 1950 (Korea) and 2022 (Ukraine) demonstrates that confidence in deterrence can prove misplaced.

Traders monitoring this market should track announcements regarding US Taiwan policy, Chinese military exercises near the strait, and any shifts in cross-strait diplomatic engagement. Taiwan's 2024 presidential transition and the 2025 US administration change represent key decision points. Scheduled Chinese military drills, statements from Beijing on "reunification timelines," and changes to Taiwan's defence posture will signal shifting risk. Recent reporting from Reuters and official statements from Taiwan's defence ministry provide baseline data on military activity and threat assessments.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
