Market context

The underlying real-world event is the 2028 US presidential election, scheduled for 7 November 2028, where the winner will be inaugurated on 20 January 2029. A current market probability of 1% for a specific outcome suggests an extreme long-shot, comparable to historical cases where a candidate entered the race with negligible early support yet surged after a pivotal primary victory or a major scandal reshaping the field. Such low probabilities often reflect the absence of a clear frontrunner or the dominance of incumbents, mirroring the 2016 contest where outsider candidates initially held minimal odds before capturing the nomination through unexpected momentum.

Traders should monitor key catalysts including the formal announcement of candidates, the 2026 midterms which will reshape state redistricting and party influence, and the release of early polling data. Gavin Newsom, the California governor, leads the Democratic nomination market at 24.3% due to his high national profile and frequent clashes with the Trump administration, while JD Vance and Marco Rubio top the early Republican list according to a recent Washington Post report. Critical absences or coaching changes in party leadership, alongside the positioning of surging figures like Alexandria Ocasio-Cortez, will determine whether the 1% probability holds or shifts as the race solidifies.

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 PolyGram, 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.
