Market context

The 2028 US Presidential Election will determine the nation's 46th president on 7 November 2028. Polymarket currently prices this contract at 1% implied probability, reflecting the market's assessment that a single named winner will be called by the Associated Press, Fox News, and NBC before the inauguration deadline of 20 January 2029. Resolution hinges on consensus among these three major news organisations; if disagreement persists, the contract settles based on who takes the oath of office. The USDC-denominated conditional token structure on Polygon allows traders to maintain positions through the settlement window, with payouts determined once all three sources align on a victor or the constitutional threshold passes.

Historical precedent suggests close elections occasionally delay media calls but rarely prevent consensus by inauguration. The 2020 election saw major networks call the race four days after polling closed, whilst 2000's Florida recount extended uncertainty to December before the Supreme Court intervened. A genuinely contested 2028 result—involving multiple states with razor-thin margins or legal challenges—would be the primary scenario testing this contract's resolution mechanics. The current 1% pricing reflects confidence in a decisive outcome or swift media consensus rather than a high probability of genuine ambiguity persisting through January 2029.

Key catalysts include the Democratic and Republican National Conventions in summer 2028, major party nominee announcements, and October polling trends. Election night reporting on 7 November itself will be critical; if networks diverge significantly in their calls, traders should monitor legal filings and state certification timelines through December. The Federal Reserve's economic data releases and any late-campaign developments affecting voter sentiment will influence underlying election dynamics that feed into market pricing.

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.
