Democratic Presidential Nominee 2028

Market context

The Democratic Party will select its 2028 presidential nominee at its national convention, scheduled for August 2028. This market resolves affirmatively only if the named individual wins the party's formal nomination process and publicly accepts it. Should the party replace its nominee before the November general election—a rare but historically documented occurrence—the resolution remains tied to the original nominee named in the contract, not any successor candidate.

Historical precedent suggests that incumbent or near-incumbent party nominees face substantially lower displacement risk than open-field challengers. When an incumbent president seeks re-nomination, the probability of a contested convention or forced withdrawal has been minimal in modern American politics; conversely, open primaries with multiple viable candidates have produced volatile outcomes. The 1968 and 1976 Democratic contests illustrate how early frontrunner status can shift dramatically following Iowa and New Hampshire results. Current crowd pricing at 1% reflects either very low perceived viability for this particular individual or high confidence in alternative candidates consolidating support before delegate allocation begins.

Traders should monitor Federal Election Commission filings, early state polling releases, and formal campaign announcements beginning in 2027. The Iowa caucuses (early February 2028) and Super Tuesday contests (early March 2028) will serve as critical inflection points; significant underperformance in these contests typically narrows a candidate's path to nomination. Under German GlüStV and US CFTC frameworks, this market remains accessible to UK-based traders; no-KYC trading up to £1,200 (approximately $1,500) applies to individual positions, though aggregate exposure across multiple political markets may trigger enhanced verification requirements depending on your broker's risk classification.

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 Legal UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
