These markets track the share of votes the Spanish Socialist Workers' Party (PSOE) might receive in the 2026 general election. The outcome depends on the final certified vote percentage PSOE achieves in the Congress of Deputies election, as officially announced by Spanish authorities.
All markets resolve based on the certified vote percentage for PSOE in the 2026 Spanish general election for the Congress of Deputies, as officially published by the Spanish Ministry of the Interior and proclaimed by the Junta Electoral Central. The percentage is calculated by dividing PSOE's total votes by the number of valid votes cast (including blank ballots, which are counted as valid under Spanish law), then multiplied by 100. Only votes in the Congress of Deputies election count; Senate votes are excluded. Invalid ballots are not counted in the denominator. Votes for PSOE include those for the Socialists' Party of Catalonia (PSC-PSOE) and any other lists aggregated under PSOE in the national results. Each market has a different threshold: if the certified percentage meets or exceeds the specified threshold (from 21% to 31%), that market resolves to Yes; otherwise, it resolves to No.
Currently, prediction market odds offer a distinct perspective compared to traditional analyst forecasts for the Spanish election outcome. While polls and expert predictions provide valuable insights, this market aggregates the collective wisdom of a diverse group of traders. Discrepancies can arise due to differing methodologies, biases, or access to information. It's common to see this market react more quickly to new information or shifts in sentiment than traditional forecasts, offering a dynamic and responsive view of potential election results. Examining these differences can be a useful exercise in understanding the range of possible outcomes.
On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing different PSOE vote share percentages. The price of each contract reflects the market's assessment of the probability of that outcome occurring. As more traders participate, the prices adjust to reflect the evolving consensus. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The prices are denominated in USD, and traders aim to profit by correctly predicting the final outcome of the election. The market's depth and volume indicate the level of confidence traders have in their predictions.
This market resolves around Dec 15, 2026, with the outcome confirmed once the official results of the Spanish general election are verifiable from credible public reporting. The final PSOE vote percentage, as reported by official sources, will determine the winning contracts. Traders who correctly predicted the outcome will receive a payout based on the contract's price at resolution. The market will close prior to the official announcement to prevent manipulation and ensure a fair and transparent resolution process. The resolution will be based on the official count.
Several signals or events could significantly move this market before it resolves. Major political developments, such as significant policy announcements from leading parties, unexpected shifts in public opinion revealed by new polls, or prominent endorsements could all influence trader sentiment. Economic news, particularly data related to Spain's economic performance, could also play a role. Any event that alters the perceived likelihood of the PSOE's success, or the overall political landscape, has the potential to cause price fluctuations in this market. Unexpected campaign events or scandals could also have a substantial impact.
