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 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 primarily ranked by the number of seats won in the specified election, counted according to the attribution rules below. If two or more parties are tied on seats, ties will be broken by the total number of valid votes received nationwide by each party, including votes attributed to its regional designations, with higher vote totals ranking higher. Votes attributed to PSC will count toward PSOE. Votes cast for a joint coalition list will not count toward an individual constituent party for this tie-break, even where elected candidates from that list count toward the party’s seat total. 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 highest finishing position after applying this ranking.

Seats will be counted where they are attributed to the specified party. If a listed party contests the election under a regional designation, all seats and votes attributed to that designation will count toward the listed party. For example, the Partit dels Socialistes de Catalunya (PSC) will be treated as a regional designation of PSOE. If a listed party contests as part of a coalition, only seats won by candidates who were members of the listed party on election day will count toward that party. Except as provided above, seats attributed to another party or electoral designation will not count, regardless of electoral cooperation, endorsements, coalition agreements, or subsequent changes in party affiliation or parliamentary-group membership.

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/).

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome PP currently trades at 82.5%, but our AI places its Fair Value at just 69.3%. This creates a large negative EV Gap of -13.2%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
