Next is PCN at 4.3%. Only Polymarket lists this market, so there is no second price to compare.
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 2 min ago. Ages are as of when this page was built.

Live prediction market odds for "Which party will gain most seats in El Salvador Legislative Election?". Nuevas Ideas (NI) leads at 87.2%. Next is PCN at 4.3%. $6K has traded across 11 outcomes on Polymarket. The market is expected to resolve by Mar 1, 2027.
Legislative elections to elect the 60 members of the Legislative Assembly of El Salvador are scheduled to take place on February 28, 2027. This market will resolve according to the political party that gains the greatest number of seats in the 2027 Salvadoran legislative election, compared to before the election. For the purposes of this market, the number of seats a party held before the election will be the number of seats attributed to that party in the official final results of the February 4, 2024 Salvadoran legislative election, as published by the Supreme Electoral Tribunal of El Salvador: Nuevas Ideas (NI) 54, ARENA 2, PCN 2, PDC 1, and Vamos 1. All other parties will be considered to have held 0 seats. Changes to the composition of the Legislative Assembly after the 2024 election, including resignations, replacements, party switches, or changes in parliamentary-group affiliation, will not be considered. A party's seats gained will be calculated as the number of seats attributed to that party in the official results of the 2027 election minus the number of seats it held before the election, as defined above. This figure may be zero or negative. If the results are not known definitively by February 29, 2028, 11:59 PM ET, this market will resolve to "Other". In the event of a tie between multiple parties for the most seats gained, this market will resolve in favor of the party that received a greater number of valid votes. In the event that results in a tie, this market will resolve in favor of the party whose listed abbreviation appears first in alphabetical order. Seats will be counted only where they are attributed to the specified party. Seats attributed to another party or electoral designation will not count, regardless of electoral cooperation, endorsements, coalition agreements, or subsequent parliamentary-group arrangements. This market's resolution will be based solely on the number of seats gained by the named party in the Legislative Assembly of El Salvador. This market will resolve based on the results of this election, as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results reported by the Supreme Electoral Tribunal of El Salvador (https://www.tse.gob.sv/).
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.
