Will China invade Taiwan by end of 2026?

Platform comparison

Market context

The real-world event at the heart of this market is whether China will launch a full-scale military offensive to seize any part of Taiwan before the end of 2026. In prediction markets, a YES share pays out if this event occurs, while a NO share pays out if it does not; the current crowd-implied probability of 4% suggests traders see an imminent invasion as highly unlikely. This low figure aligns with historical precedents such as the 2022 Fourth Taiwan Strait Crisis, where China conducted massive drills but stopped short of invasion, and the widely cited "Davidson window" of 2027, which many Western analysts believe is the earliest plausible date for a serious attempt [2][5].

Traders should monitor key catalysts including US defence policy shifts, Chinese military purges, and Taiwan’s readiness drills, as these directly influence invasion calculus. Recent reports from the US intelligence community state that an imminent military action is improbable, noting that Beijing views the costs of invasion as prohibitively high and is instead pursuing non-military unification [2]. Meanwhile, Taiwan’s Defence Minister Wellington Koo has warned that the warning time for any potential Chinese assault is shortening, prompting five days of immediate combat readiness drills this week [4]. Experts also stress that China’s primary decision this year hinges on whether the US will intervene, as a lack of US involvement would make a Chinese campaign significantly easier [3].

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.
