Democratic Presidential Nominee 2028

Market context

The Democratic Party will select its 2028 presidential nominee at its national convention, scheduled for August 2028, ahead of the November general election. This market resolves affirmatively only if the specified individual wins the party's nomination vote and formally accepts it; any subsequent replacement before election day does not alter the resolution outcome. The settlement window closes on 7 November 2028, the day of the general election itself.

Historical precedent suggests that 1% implied probability reflects either a candidate with minimal party establishment backing or one facing substantial structural headwinds within the Democratic coalition. Since 1992, every Democratic nominee has either been the sitting president seeking re-election or emerged from a competitive primary field where frontrunner status crystallised by Iowa and New Hampshire. Incumbent advantage in nomination contests is pronounced: sitting presidents have secured renomination in every cycle since 1976 when Gerald Ford faced Ronald Reagan. Conversely, open-seat Democratic nominations—1992, 2000, 2008, 2016, 2020—have typically consolidated around candidates demonstrating early polling strength and donor networks by autumn of the preceding year.

Key catalysts include formal campaign announcements (typically autumn 2027 onwards), Iowa caucuses and New Hampshire primary results (January–February 2028), and Super Tuesday outcomes in March. The Democratic National Committee's delegate allocation rules, reformed after 2016 to reduce superdelegates' first-ballot influence, will shape whether a candidate can accumulate the required majority before the convention. Regulatory accessibility varies: under German GlüStV provisions, EU traders face stricter KYC requirements; US CFTC oversight applies to US-domiciled participants; many platforms permit no-KYC trading up to $1,500 notional exposure, though this market's settlement dependency on Democratic Party official sources creates additional verification burdens at resolution.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
