Resolution criteria on PolyGram: This market will resolve to “Yes” if the named individual wins and accepts the 2028 nomination of the Republican Party for U.S. president. Otherwise, this market will resolve to “No”. The resolution source for this market will be a consensus of official Republican Party sources.

The event is whether the eventual Republican nominee for president in 2028 is the named candidate, with settlement tied to official party sources and not altered by any later replacement before election day. A 2% implied chance leaves the market treating a win-and-acceptance outcome as a long shot, which is consistent with how early nominating markets price in years of uncertainty. Polymarket’s order book is forming that probability today through small bids and asks rather than any settled convention outcome, so the quoted level mostly reflects current trader appetite, not a forecast anchored in ballots or delegate counts.
Historical precedent suggests caution in reading early nomination prices too literally. Party favourites at this stage often change once campaigning begins, donors consolidate, and the primary calendar starts to reward organisation over name recognition. Recent public polling gives some shape to the field: YouGov found JD Vance the most commonly considered Republican option among Republicans and Republican-leaning independents, while Polymarket’s wider 2028 presidential market has shown Vance, Marco Rubio and Gavin Newsom among the leading early names. For this nomination market, traders should watch formal candidacy announcements, fundraising and endorsement signals, debate and primary scheduling, and any change in the party’s rules or convention process, since the settlement depends on the official nominee and acceptance, not on pre-election speculation.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
For this market, the resolution date is 7 November 2028. A UMA proposer can submit the outcome from that moment; the two-hour dispute window closes at , and assuming no counter-claim is staked, winning USDC clears to trader balances by approximately .
If a dispute is filed inside the two-hour window, the outcome escalates to UMA token-holder voting, which extends settlement by roughly 48 hours. This particular market has no public resolution feed listed; disputes here are more likely if the underlying outcome is subject to interpretation, in which case the UMA token-vote arbitrates the wording of the original market question.
Political markets occasionally see longer settlement when outcomes hinge on official certification rather than the polling result itself — the proposer waits for the certifying body's announcement, which can push payout 12-48 hours past the calendar end-date. Funds clear directly to your in-app USDC balance on Polygon. Withdrawals are non-custodial: send to any address you control, typical confirmation under 30 seconds, gas paid in USDC if you'd rather not hold MATIC.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose. For "Republican Presidential Nominee 2028", the considerations above apply directly — Political markets are exposed to information asymmetry between insider and retail traders, and to last-minute polling shifts that can move the line 15-20¢ in the final 48 hours. Long-dated political contracts also carry meaningful time decay if the underlying race is close.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
