Will China invade Taiwan by December 31, 2027?

Resolution Criteria

This market will resolve to "Yes" if China commences a military offensive intended to establish control over any portion of the Republic of China (Taiwan) by December 31, 2027, 11:59 PM ET. Otherwise, this market will resolve to "No". Territory under the administration of the Republic of China, including any inhabited islands, will qualify; however, uninhabited islands will not qualify. The resolution source for this market will be official confirmation by China, Taiwan, the United Nations, or any permanent member of the UN Security Council; however, a consensus of credible reporting will also be used.

Prediction markets currently price a 'No' resolution as the heavily dominant outcome for whether China will invade Taiwan by 31 December 2027, with the 'Yes' outcome carrying a small minority of market volume. The market resolves on official confirmation from China, Taiwan, the United Nations, or any permanent member of the UN Security Council — or, alternatively, a consensus of credible reporting — by 31 December 2027.

Market structure

This is a binary market with two possible outcomes: 'Yes' (China commences a military offensive against Taiwan-administered territory by the deadline) or 'No' (it does not). Volume is heavily concentrated on the 'No' outcome. Only inhabited territory under the Republic of China's administration qualifies for a 'Yes' resolution; uninhabited islands do not. Resolution may draw on official governmental or UN confirmation, or a credible-reporting consensus if formal confirmation is absent.

Background

Cross-strait tensions have been a persistent feature of East Asian geopolitics since the Chinese Civil War concluded in 1949, when the Republic of China government retreated to Taiwan. The People's Republic of China regards Taiwan as a breakaway province and has never renounced the use of force to achieve reunification. In recent years, military activity in the Taiwan Strait has intensified — including large-scale People's Liberation Army exercises, increased air incursions into Taiwan's air defence identification zone, and elevated naval activity. These developments, alongside broader US–China strategic competition, have drawn significant international attention and placed Taiwan at the centre of global security debate.

Key factors

Several structural factors bear on how this market could resolve. First, the pace and scale of PLA military modernisation directly affects the credible threat calculus. Second, US defence commitments to Taiwan — and how clearly or ambiguously they are signalled — influence deterrence calculations on all sides. Third, Taiwan's own presidential leadership and cross-strait policy posture can affect diplomatic temperature. Fourth, any shift in the broader US–China relationship, including trade or technology disputes, could alter strategic incentives. Fifth, internal Chinese political dynamics, including the stability of current leadership priorities and economic conditions, shape the timing and appetite for military action. Finally, the behaviour of regional powers — Japan, South Korea, Australia — and their security postures affect the broader risk environment within which any decision would be made.
