Republican Presidential Nominee 2028

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 named individual wins the nomination and formally accepts it; any subsequent replacement before election day does not alter the resolution. The 2% implied probability reflects either a candidate with minimal primary support or one facing significant structural barriers to securing delegate majorities.

Historical precedent suggests Republican nomination contests remain unpredictable until late in the primary calendar. In 2016, Donald Trump held single-digit polling through much of 2015 before winning Iowa and New Hampshire; conversely, candidates with early frontrunner status—Jeb Bush in 2016, Mitt Romney's challengers in 2012—failed to convert polling leads into nominations. The 2028 field remains fluid, with no declared candidate yet dominating delegate projections as of late 2024. A 2% probability typically indicates either a long-shot candidate or one whose nomination path depends on multiple unlikely contingencies.

Traders should monitor formal campaign announcements, state filing deadlines (which begin in autumn 2027), and early primary results from Iowa and New Hampshire in January and February 2028. The Republican National Committee's delegate allocation rules, unchanged materially from 2024, favour front-runners in winner-take-all contests. Under German GlüStV and US CFTC frameworks, this market remains accessible to UK traders; the no-KYC threshold of $1,500 applies to aggregate position value, meaning traders can establish positions below this tier without identity verification, though larger exposures trigger standard regulatory compliance requirements.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

FAQ

Is this market available outside the US?

Polymarket Tax UK is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, Polymarket Tax UK triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
