Market context

The Republican Party will select its 2028 presidential nominee at its national convention, scheduled for mid-July 2028. This market resolves affirmatively only if the specified individual secures and formally accepts the party's nomination. The 2% implied probability reflects either a candidate with minimal establishment backing or one facing substantial headwinds within the party apparatus. Settlement occurs after the convention concludes, with official Republican Party communications serving as the authoritative resolution source.

Historical precedent suggests that nominees with single-digit probabilities at this stage rarely capture the nomination. In 2016, pre-primary polling showed several candidates trading at similar levels who subsequently failed to gain traction; conversely, candidates with early momentum—Trump at 3–5% in mid-2015 before Iowa—occasionally defied expectations. The 2012 cycle demonstrated how quickly perceived long-shots can collapse once voting begins. For traders using conditional orders or algorithmic monitoring, the key distinction lies between structural barriers (weak donor networks, limited state organisation) and temporary polling weakness that might resolve through media coverage or debate performance.

Catalysts to monitor include formal campaign announcements, major endorsements from sitting governors or senators, and quarterly FEC fundraising disclosures. The Iowa caucuses (early February 2028) and New Hampshire primary (mid-February) will provide the first concrete electoral signals; a strong showing in either state typically correlates with improved nomination odds. Traders should track Republican National Committee rule changes and delegate allocation procedures, which directly affect path-to-nomination calculations. Recent reporting from outlets like The Hill and Politico regularly covers candidate positioning and internal party dynamics that inform nomination probability shifts.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket App UK, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
