A Republican wins Arizona's presidential election if their candidate either receives the most popular votes or is the declared winner as per the AP's call, Fox News' call, NBC's call, or official certification. The resolution criteria may depend on which source calls the race for the same candidate first. If a Republican candidate is nominated by the party and has a ballot-listed or identifiable party preference, they are considered to represent the party in this market. The outcome of this election determines whether this market resolves to "Yes" or "No". This market will resolve after all three mentioned sources have called the race for the same candidate.
