Will China invade Taiwan by end of 2026?

Platform comparison

Market context

A **YES** share pays out if China begins a military offensive intended to establish control over any inhabited part of Taiwan by the market’s deadline; a **NO** share pays out if that does not happen. The current crowd price of **4% YES** implies traders see a direct invasion as a low-probability outcome relative to continued pressure short of war.

That pricing fits the recent policy and intelligence backdrop. The US Office of the Director of National Intelligence said in March 2026 that Chinese leaders do not currently plan an invasion of Taiwan in 2027 and have no fixed timetable for unification, while expecting Beijing to keep using coercive measures around Taiwan instead.[1][5] Reuters similarly reported that US intelligence sees no immediate invasion plan and expects China to pursue control through non-military means, with analysts noting that a full amphibious assault would be difficult and risky.[6] For prediction markets, that matters because the event requires an overt military offensive, not just drills, air sorties, cyber pressure, or blockade-like signalling.

Traders should watch for three kinds of catalysts: formal Taiwanese or Chinese statements, large-scale PLA mobilisation or new exercise patterns, and any major changes in US or allied posture that alter Beijing’s calculus. Recent reporting and analysis have stressed that China is still building pressure around Taiwan through sanctions, exercises, and political warfare, rather than clearly committing to invasion timing.[1][13] In practice, the market is likely to react less to routine cross-strait tension than to evidence of launch preparation, amphibious concentration, or official confirmation from governments or the UN system, because those would move the event from deterrence and coercion into the settlement definition’s military-offensive threshold.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
