Will China invade Taiwan by December 31, 2027?

Platform comparison

Market context

The underlying question concerns whether the People's Republic of China will initiate a military campaign to seize control of Taiwan or its inhabited territories before the end of 2027. Such an action would constitute a cross-strait invasion under the market's definition, requiring official confirmation from Beijing, Taipei, the UN, or a permanent Security Council member. The 14% implied probability reflects assessments that whilst tensions remain elevated, a full-scale military offensive within the next three years remains a low-probability tail event.

Historical precedent offers limited direct comparison; the last major cross-strait military confrontation occurred during the 1995–96 Taiwan Strait Crisis, which involved missile tests and exercises but no invasion attempt. More recent analogues include Russia's 2022 invasion of Ukraine and the 2014 Crimea annexation, both of which shifted market perceptions of great-power military risk. Taiwan's defensive capabilities have strengthened materially since the 1990s, whilst US security commitments—though ambiguous by design—remain a significant deterrent. The absence of a military offensive over the past 75 years, despite recurring political tensions, anchors baseline expectations toward continued status quo.

Traders monitoring this market should track statements from Taiwan's defence ministry, Chinese military exercises in the Taiwan Strait, and US arms sales announcements, all of which serve as proxies for escalation risk. The 2024 Taiwan presidential transition and any subsequent shifts in cross-strait dialogue merit close attention. Regulatory access varies by jurisdiction: UK traders face no KYC requirement for positions under £1,500 under Gambling Commission guidance, whilst US-based traders remain subject to CFTC restrictions on prediction market participation. German traders should note GlüStV compliance requirements for derivative positions.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
