Will China invade Taiwan by December 31, 2027?

Platform comparison

Market context

China launching a military offensive to seize any part of Taiwan before the end of 2027 is the event this market is pricing, and a **Yes** share pays out if that happens, while a **No** share pays out if it does not. The current crowd-implied probability of **14% Yes** suggests traders see the risk as real but still distinctly below even odds, consistent with the market’s own definition that covers formal military action aimed at control, not just pressure or rhetoric.

For context, prediction markets on Taiwan tend to discount the gap between *readiness* and *decision*. U.S. intelligence has said China does not currently plan to invade Taiwan in 2027 and has no fixed timeline for unification, while also warning that Beijing is continuing coercive military and political pressure around the island.[2][7] That distinction matters: many analyses treat 2027 as a capability benchmark rather than a committed launch date, which helps explain why the market can sit in the low teens even while headlines remain tense.[14]

The main catalysts traders should watch are official military drills, changes in cross-strait rhetoric, U.S.-Taiwan defence signalling, and any shift in Beijing’s diplomatic posture. Recent coverage has emphasised that Washington now assesses an imminent attack as unlikely, but also expects China to keep building pressure short of war.[6][15] Any evidence of mobilisation, blockade rehearsal, or unusually explicit political instructions from Beijing would matter more than routine exercises, because this market resolves only if China starts an offensive intended to establish control, not merely if tensions rise.

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

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.
