Market context

Americans will elect their next president on 7 November 2028, with the winner taking office on 20 January 2029. The crowd currently prices this outcome at 1% probability, implying near-certainty that a specific candidate will be named. Resolution requires agreement from the Associated Press, Fox News, and NBC; if all three have not called the race by inauguration day, the market settles on whoever is sworn in.

The 1% residual probability reflects genuine structural uncertainty rather than doubt about whether an election occurs. Historical precedent shows close contests can delay media calls: the 2000 Florida recount saw networks retract calls and dispute outcomes for weeks, whilst the 2020 election took four days for major outlets to declare a winner as mail-in ballots were counted. A genuinely competitive 2028 race in swing states—particularly if margins fall within recount thresholds in Pennsylvania, Michigan, or Wisconsin—could prevent unanimous media consensus before January 20th, forcing settlement on inauguration outcomes instead.

Traders should monitor primary season through spring 2028 for candidate clarity, as late-breaking nominee changes or health crises affecting frontrunners could reshape race dynamics. The summer party conventions in July will crystallise the matchup. Autumn polling trends and October surprises historically move markets sharply; the final weeks before November will determine whether the race tightens enough to create genuine call-delay risk. Economic data, international incidents, and campaign momentum shifts all feed into whether the eventual margin allows swift media consensus or creates the conditions for the residual 1% scenario to materialise.

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.
