How Election Markets Resolve
Resolution sources vary by market:
- US elections: Associated Press race call is the standard resolution source
- UK elections: Official BBC call or Electoral Commission declaration
- EU elections: Official electoral authority announcement
- Disputed outcomes: UMA oracle token-holder vote after a 2-hour dispute window
Markets typically resolve within hours of a clear winner, and USDC payouts land on Polygon within minutes of resolution.
Types of Election Markets
- Win probability: "Will [candidate] win the election?" — most common format
- Party control: "Which party will control [chamber]?"
- Vote share: "Will [party] get more than X% of the vote?"
- Timing: "Will the election be called before [date]?"
- Policy: "Will [policy] pass within 90 days of the election?"
Proven Trading Strategies
Fading overreaction: Media coverage of a debate gaffe or scandal typically moves markets too much in the short term. Patient counter-positions often return to equilibrium within days.
Poll arbitrage: When a poll shows a significant swing that seems like an outlier, markets often overweight it. Betting on mean-reversion has historically been profitable.
Primary season: Early in primary campaigns, frontrunner probabilities tend to be underweighted. The path-dependency of momentum is consistently underpriced.
Timing the news cycle: October surprises tend to overcorrect markets. Position before they correct back.
