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 secures and formally accepts that nomination. A 3% implied probability reflects the crowded field typical of open-seat contests and the historical difficulty any single candidate faces in consolidating early support into convention victory.
Comparable precedent suggests caution in reading low probabilities as dismissals. In 2016, Donald Trump held single-digit odds through much of the primary season before winning the nomination; in 2008, Barack Obama faced similar scepticism against Hillary Clinton's perceived inevitability. Conversely, frontrunners with 40%+ support have occasionally faltered—see 2012, when Mitt Romney's path remained contested through April despite leading polls. The 2028 field remains fluid; Iowa caucuses occur in January 2028, with Super Tuesday following in March. Early momentum shifts, candidate withdrawals, and consolidation patterns will reshape probabilities substantially between now and the July convention.
From a regulatory standpoint, this market's accessibility depends on jurisdiction and stake size. Under German GlüStV rules, prediction markets on political events face stricter licensing requirements than sports betting, though cross-border access from the UK remains permissible for individual traders. The US CFTC does not regulate prediction markets on political outcomes under current guidance, provided operators remain outside US jurisdiction. The "no-KYC up to $1,500" threshold common on some platforms means traders can participate in this market with minimal identity verification if their total exposure stays below that limit, though larger positions typically trigger standard know-your-customer procedures.
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.
