This PredictPedia entry covers the Polymarket event "AL-06 House Election Margin of Victory," which is tied to the 2026 U.S. House election in Alabama's 6th congressional district. The contract does not ask whether a particular party wins. It asks how large the gap is between the top two candidates. The rules define the margin of victory as the absolute difference between the percentages of valid votes received by the first-place and second-place candidates, with each percentage calculated by dividing a candidate's valid votes by the total valid votes cast in the election [1]. The market uses party labels in a specific way. Candidates nominated by the Democratic and Republican Parties represent the "Democrat" and "Republican" options, and independent candidates do not count as either party [1]. The rules say candidates may be named for the convenience of traders, and that if a named candidate is replaced as a party's nominee before election day, the contract name will be updated and the market will resolve based on the replacement nominee [1]. The contract is divided into margin brackets. The saved event includes contracts on ranges such as 0% to 10%, 10% to 20%, and 50% or more for a Republican win, along with a separate contract on whether the Democratic Party candidate wins [1]. The rules state that if a reported value falls exactly between two brackets, the market resolves to the higher margin bracket [1]. Resolution depends on official results. The primary source is the official count of the 2026 AL-06 House election as published by the state electoral authority responsible for certifying results, although an overwhelming consensus of credible reporting may also be used [1]. If a recount starts before the total becomes official, the market stays open until the recount finishes and the vote is certified [1]. If the results are not known definitively by June 30, 2027 at 11:59 PM ET, the market resolves to "Other" [1]. The contract rules say the election is currently expected to be held on November 3, 2026, and the listed end time is November 4, 2026 at 04:59 UTC [1]. That expected date comes from the contract rules and is not a separate confirmation of the schedule. Tie-breaking follows specific rules. If two listed candidates tie for the most valid votes, the market resolves to the lowest margin bracket for the candidate whose ballot-listed last name comes first alphabetically. If a listed candidate ties with an unlisted candidate, the market resolves to the lowest bracket for the listed candidate. If two or more unlisted candidates tie, the market resolves to "Other" [1].

Historical Context

The supplied sources do not provide history specific to Alabama's 6th district or its 2026 contest. They do offer general background on how U.S. elections of this type are reported. The 2018 United States House elections were held on November 6, 2018 and chose representatives from all 435 congressional districts [2]. In the 2024 Montana gubernatorial election, the winning incumbent was reported as having won by a 20% margin, larger than his 13% margin in 2020 [3]. These examples show that margins are reported as percentage differences between candidates, but they do not describe the AL-06 race.
