Legislative Assembly elections are to be scheduled to be held in Tamil Nadu, India, in March–May 2026. This market will resolve according to the political party that wins the greatest number of seats in the Tamil Nadu Legislative Assembly in the 2026 election. If the results are not known definitively by October 31, 2026, 11:59 PM ET, this market will resolve to "Other". In the event of a tie between multiple parties for the most seats won, this market will resolve in favor of the party that received a greater number of valid votes. If that also results in a tie, this market will resolve in favor of the party whose listed abbreviation appears first in alphabetical order. This market’s resolution will be based solely on the number of seats won by the named party in the Tamil Nadu Legislative Assembly. 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 Indian government, specifically the Election Commission of India (ECI) (https://eci.gov.in). If multiple official reports differ, this market will resolve based on the one that includes the greatest number of Assembly Constituencies (ACs).
