Resolution rules: read both before trusting a gap
Kalshi
If Yogi Adityanath becomes Prime Minister of India as a result of government formation following the next Indian general election and meets all constitutional requirements before Apr 30, 2030, then the market resolves to Yes.
Polymarket
This market will resolve to the next individual who officially assumes the office of Prime Minister of Serbia by June 30, 2028, 11:59 PM ET. To count for resolution, the individual must be elected by the National Assembly and be formally sworn-in, resulting in the official formation of a new government. Any interim or caretaker Prime Minister who is not elected by the National Assembly will not count toward the resolution of this market. If no such Prime Minister takes office by June 30, 2028, 11:59 PM ET, this market will resolve to “Other”. This market will resolve based on a consensus of credible reporting. If there is ambiguity, this market will resolve solely based on official information from the Serbian government.
