Market context

The Republican Party will select its 2028 presidential nominee at its national convention, scheduled for mid-July in Milwaukee. The nominee must secure a majority of delegate votes on the convention floor. This particular market resolves to "Yes" only if the named individual both wins the nomination and formally accepts it; any subsequent replacement before November does not alter the resolution outcome.

Historical precedent suggests that sitting presidents or their chosen successors typically command overwhelming delegate support at renomination conventions. Since 1976, only one sitting president faced a serious primary challenge that reached the convention floor. The 2% implied probability reflects the substantial structural advantage held by frontrunners in delegate accumulation during the primary phase. Early polling aggregators, including FiveThirtyEight's 2024 Republican primary tracker, demonstrated how quickly probabilities shifted once candidates either consolidated endorsements or withdrew from contention. The nominee's identity will likely crystallise during the primary season between Iowa's caucuses in January 2028 and Super Tuesday contests in March.

Traders should monitor several near-term catalysts: formal campaign declarations typically cluster in the autumn preceding an election year, whilst Federal Election Commission filings reveal funding trajectories and donor commitment. The Republican National Committee's delegate allocation rules, finalised at their summer 2027 meeting, will shape which candidates can viably accumulate the required 1,215 delegates. Convention floor dynamics remain unpredictable if no candidate enters Milwaukee with overwhelming support, though this scenario has grown rarer in modern Republican politics. Recent reporting from The Hill and Politico will track candidate positioning and endorsement patterns as the primary season approaches.
