About this market

Live prediction market odds for "Spain General Election: 3rd Place". BC Greens leads at 97%. Next is Vox at 83%. $38K has traded across 10 outcomes on Kalshi and Polymarket. The market is expected to resolve by Nov 30, 2026.

Legislative elections to elect the 350 members of the Congress of Deputies of Spain are scheduled to take place on November 29, 2026. This market will resolve according to the political party that wins the third-greatest number of seats in the Congress of Deputies of Spain as a result of this election. If the results of the specified election are not definitively known by November 30, 2027, 11:59 PM ET, this market will resolve to "Other". Parties will be ranked by the number of seats won by their electoral lists (candidaturas) nationwide in this election, attributed as set out below. If two or more parties are tied on seats, ties will be broken by the total number of valid votes received by their lists nationwide, with higher vote totals ranking higher. If parties remain tied, ties will be broken by alphabetical order of the listed party names. This market will resolve to the party that occupies the third finishing position after applying this ranking. Seats and votes will be attributed according to the electoral list on which they were obtained, as reported in the official results, regardless of the party membership of individual candidates. Lists will be attributed as follows: PSOE: lists of the Spanish Socialist Workers' Party, including the Partit dels Socialistes de Catalunya (PSC) lists in Catalonia. PP: lists of the People's Party, including the joint UPN–PP list in Navarre. Broad Front (FA): all Broad Front lists, including Catalunya en Comú in Catalonia, Compromís–Valencian Front in the Valencian Community, and Canarian People’s Unity (UPC) in the Canary Islands. ERC: Republican Left of Catalonia lists, including the joint ERC–Podem lists in Catalonia. Podemos: only lists presented by Podemos on its own. CCa: Canarian Coalition lists, including the joint CCa–1º CAN lists in the Canary Islands. Any other list will be attributed to the party or coalition that presents it, as named in the official proclamation of candidacies. Electoral cooperation, endorsements, coalition agreements, or subsequent changes in party affiliation or parliamentary-group membership will not be considered. This market will resolve based on the results of the elections, as indicated by a consensus of credible reporting. In the case of ambiguity, this market will resolve solely based on the results as reported by the Spanish Ministry of the Interior (https://infoelectoral.interior.gob.es/).

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.
