Will China invade Taiwan by December 31, 2027?

Platform comparison

Market context

China’s potential military offensive against Taiwan by the end of 2027 remains a live geopolitical risk, with Polymarket pricing the “Yes” outcome at 14¢, implying a 14% crowd-sourced probability that such an invasion will commence before the settlement window closes on 31 December 2027[1]. This on-chain contract, settled in USDC on the Polygon network via conditional tokens, shifts in real time as traders react to new intelligence and diplomatic developments[4]. The market does not predict certainty but reflects collective risk assessment: if “Yes” trades at 14¢, the crowd assigns a 14% chance the event occurs[1].

Historically, the 2027 timeline stems from the “Davidson Window,” a 2021 US Senate testimony warning that China’s military readiness to invade Taiwan could manifest within six years—not that war is inevitable by then[5]. Experts clarify that 2027 marks when the PLA is expected to gain offensive capability, not a fixed invasion deadline[7]. Recent US intelligence assessments now state Beijing has no fixed timeline and prefers unification without force if possible[6]. This nuance frames the current 14% probability as cautious but not dismissive of escalation risks.

Traders should monitor China’s military parade next month, where new weaponry will be showcased, and any shifts in US-China diplomatic talks or Taiwan’s defence posture[2]. Key catalysts include Xi Jinping’s public statements on unification, PLA readiness announcements, and potential cross-strait incidents involving warplanes or naval vessels in Taiwanese airspace[2]. A sudden change in US defence commitments or a Taiwanese independence declaration could rapidly alter the probability, as Chinese law permits force under specific conditions, not fixed dates[8].

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.
