The Republican National Committee is the deciding source, and the outcome is determined once a candidate is nominated and accepts the nomination at the Republican National Convention. The outcome is Yes if the candidate named in the market question is that nominee and No otherwise. It can be decided early if the Associated Press, The New York Times and The Wall Street Journal have each called the nomination for the same candidate, confirming that the candidate has clinched enough delegates to win on the first ballot, unless that happens within 30 days of the convention or there is credible uncertainty about delegate counts or possible changes before the convention; otherwise it stays open until the party formally nominates its candidate, with resolution scheduled for 8:00 AM CT on the day after the convention ends. A candidate who formally withdraws, fails to file by the filing deadline or is publicly confirmed as no longer seeking the office at least 14 days before the election may resolve to No, and that result does not change if the candidate later re-enters. If the official nomination record is delayed, resolution waits until it is published.
