Odds by venue

Consensus blends each venue’s last price, weighted by how much has traded there. 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.

2 of 9 prices are live from the exchange feeds; the rest come from our regular price polls, the oldest 6 h ago. Ages are as of when this page was built.

Mostly the same bet: two differences

Where they differ

  • Generic non-US election template: rules are not uniform across events and need a per-event rules comparison before parity can be claimed.
  • Trading closes at different times: Nov 28, 2026, 11:59 PM UTC on Polymarket and Nov 28, 2027, 3:00 PM UTC on Kalshi.

Taiwanese local elections are scheduled to be held on November 28, 2026. This market will resolve according to the candidate who becomes the next Mayor of Taipei as a result of this election. Temporary, interim, or placeholder Mayors appointed before the election will not be considered. If the result of this election isn't known, or no candidate has been elected, by June 30, 2027, 11:59 PM ET, the market will resolve to "Other". This market will resolve based on the results of the elections as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the Taiwanese government, specifically the Central Election Commission (https://db.cec.gov.tw/).

Questions

What does the consensus price mean?

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%.

How is the payout worked out?

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.

Why do the venues show different prices?

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.

Is a price gap an arbitrage?

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.

How fresh are these prices?

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.
