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 18 days ago. Ages are as of when this page was built.

Final prediction market prices for "Brazil Chamber of Deputies Election Winner". PL last traded at 99.3%. Next is Avante at 0.1%. $143K has traded across 15 outcomes on Polymarket. The market closed on Oct 4, 2026.
The next federal Chamber of Deputies election is scheduled to take place in Brazil on October 4, 2026. This market will resolve according to the political party or electoral federation that holds the greatest number of seats in the next Brazilian Chamber of Deputies (Câmara dos Deputados) as a result of the next Brazilian Chamber of Deputies election. In the event of a tie between multiple entities for the most seats held, this market will resolve in favor of the entity whose listed abbreviation appears first in alphabetical order. This market's resolution will be based solely on the number of seats held by the named party or electoral federation in the Brazilian Chamber of Deputies as a result of the next Brazilian Chamber of Deputies election, not by any coalition it may be a part of. If the result of this election isn't known definitively by June 30, 2027, 11:59 PM ET, the market will resolve to "Other". This market will resolve based on the result of the election, 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 Brazilian government, specifically the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) (e.g., www.tse.jus.br/eleicoes/resultados-eleicoes) or the Brazilian Chamber of Deputies (https://www.camara.leg.br/).
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.
