Resolution rules: read both before trusting a gap
Polymarket
This market will resolve to the next individual who officially assumes the office of Prime Minister of Romania by December 31, 2027, 11:59 PM ET. To count for resolution, the individual must be formally appointed by the President of Romania and receive a vote of confidence from Parliament, resulting in the official formation of a new government. Any interim or caretaker Prime Minister who does not receive a parliamentary vote of confidence will not count toward the resolution of this market. If no such Prime Minister takes office by December 31, 2027, 11:59 PM ET, this market will resolve to “Other”. The primary resolution source for this market will be official information from the Government of Romania; however, a consensus of credible reporting may also be used.
Kalshi
If the first new person to hold Prime Minister of Romania after Issuance is Alexandru Nazare, then the market resolves to Yes.
