Will China invade Taiwan by December 31, 2027?

Platform comparison

Market context

A military invasion of Taiwan by the People's Republic of China would represent the most significant geopolitical rupture since the Cold War's end. The resolution criteria require an actual offensive operation—not rhetoric, military exercises, or blockade—intended to seize territory administered by the Republic of China. The 16% implied probability reflects a market consensus that such an event remains unlikely within the next three years, though non-negligible given regional tensions and military modernisation trajectories.

Historical precedent offers limited direct comparison. The 1950 Korean invasion and 1982 Falkland Islands conflict occurred in different strategic contexts; more relevant are the 1995–96 Taiwan Strait crisis and subsequent decades of military posturing without escalation. Cross-strait military incidents have occurred regularly—most recently the 2024 Philippines resupply missions to Ilo Ilo and Chinese coast guard confrontations—yet have remained below the threshold of full-scale offensive operations. The absence of invasion across 75 years of PRC existence, despite military capability growth, anchors the baseline probability downward.

Traders should monitor Taiwan's presidential statements, US arms sales announcements, and PLA exercise schedules as leading indicators. The 2024 Taiwan presidential transition and any shifts in US strategic posture toward Taiwan warrant close attention. Programmatically, conditional orders tied to specific geopolitical announcements—such as major US policy reversals or explicit PRC military mobilisation statements—would allow systematic exposure without continuous manual monitoring. Resolution dependency on UN Security Council or permanent member confirmation introduces a secondary layer of political negotiation that could delay or complicate settlement even if military action occurs.
