How Election Markets Resolve
Resolution mechanisms differ depending on the election type:
- US elections: The Associated Press declaration serves as the authoritative resolution standard
- UK elections: BBC official announcement or Electoral Commission confirmation
- EU elections: Designated electoral body's formal proclamation
- Contested results: UMA oracle governance vote following a 2-hour challenge period
Settlements occur shortly after a victor is determined, with USDC distributions reaching Polygon accounts within minutes of contract closure.
Types of Election Markets
- Win probability: "Will [candidate] win the election?" — the predominant structure
- Party control: "Which party will command [legislative body]?"
- Vote share: "Will [party] receive above X% of ballots?"
- Timing: "Will the election conclude before [date]?"
- Policy: "Will [legislation] be enacted within 90 days post-election?"
Proven Trading Strategies
Fading overreaction: Journalistic narratives surrounding a debate stumble or controversy frequently distort prices excessively in the near term. Contrarian bets typically converge back to fair value within several days.
Poll arbitrage: Whenever polling data indicates a dramatic movement that appears anomalous, contract prices frequently amplify the signal. Positioning for regression toward historical norms has demonstrated consistent returns.
Primary season: During early primary phases, leading contenders' odds tend to be suppressed. The self-reinforcing nature of campaign momentum remains systematically undervalued.
Timing the news cycle: Late-campaign revelations typically cause disproportionate market swings. Establishing positions ahead of normalisation can prove rewarding.
