Market context

The Democratic Party's 2028 presidential selection process remains in its earliest phase, with no formal nominee yet declared and the convention scheduled for August 2028. Current market pricing at 1% reflects the substantial uncertainty inherent in any open nomination contest more than two years away, where multiple candidates typically emerge and consolidate support through primary elections and delegate accumulation.

Historical precedent suggests that front-runner positioning shifts considerably during the pre-primary period. In 2016, Hillary Clinton entered the cycle as the presumptive nominee but faced sustained pressure from Bernie Sanders; in 2008, Barack Obama's emergence as a viable challenger to Clinton demonstrated how late-stage candidate entry can reshape delegate mathematics. The 2028 cycle differs in that President Joe Biden's current tenure creates an unusual dynamic—sitting presidents typically face minimal primary opposition, yet the party's direction post-2024 remains unsettled. Early indicators from Iowa and New Hampshire polling, expected to materialise in late 2027, will provide the first substantive signal of whether this particular candidate maintains or loses viability.

Traders should monitor Democratic National Committee procedural announcements regarding primary scheduling and delegate allocation rules, which the party typically finalises by mid-2027. State-level primary dates and any rule changes affecting how delegates are awarded will directly influence which candidates can build momentum. Additionally, any formal campaign announcements or major endorsements from party leadership will signal shifting consensus. The Iowa caucuses, scheduled for early 2028, will serve as the critical inflection point where theoretical support converts into actual delegate counts.

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

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.
