Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.
Prices come from our regular polls of each venue, the oldest 159 days ago. Ages are as of when this page was built.

Final prediction market prices for "Trump endorses China's claim to Taiwan this week?". Yes last traded at 0.2%. $1.4M has traded across 1 outcome on Polymarket. The market closed on May 17, 2026.
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.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
