What to track next

  • Verify the resolution source on this page — exchange feed, official release, news consensus — before treating any move as new information.
  • Wait for the UMA proposal to settle (current status: proposed) — price moves now reflect oracle dynamics, not odds.

Verification actions only — never trade recommendations.

Each factor is grounded in a single named metric you can verify on this page — probability, volume, liquidity, signal, resolution state. No predictions, no prose hallucinations.

Market Description

This market will resolve to “Yes” if Donald Trump publicly endorses China’s claim to Taiwan by May 17, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. “China’s claim to Taiwan” refers to the position that Taiwan is part of China, that Taiwan should be unified with China, or that the People’s Republic of China has sovereignty over Taiwan. Donald Trump will be considered to have endorsed China’s claim to Taiwan if Donald Trump publicly states that he or the United States accepts, recognizes, agrees with, or otherwise supports China’s claim to Taiwan. Statements that merely acknowledge China’s position, refer to the United States’ existing “One China” policy, call for peaceful resolution of China-Taiwan issues, or discuss Taiwan without clearly endorsing China’s claim to Taiwan will not qualify. Statements that are contingent on uncertain future events will not qualify unless they include a clear and present endorsement of China’s claim to Taiwan. Written public statements from Donald Trump (e.g., posts from his personal Truth Social account) will qualify. Videos posted on his social media accounts will also qualify for a "Yes" resolution. The primary resolution source for this market will be official statements from Donald Trump; however, a consensus of credible reporting may also be used to verify the details of a qualifying statement.
