How Election Markets Resolve
Resolution mechanisms depend on the specific election:
- US elections: Associated Press declaration serves as the authoritative resolution criterion
- UK elections: BBC official announcement or Electoral Commission statement
- EU elections: Relevant national electoral body's formal pronouncement
- Contested results: UMA protocol governance vote following a 2-hour challenge period
Settlement typically occurs within hours following a definitive outcome, with USDC transfers completing on Polygon within minutes after market closure.
Types of Election Markets
- Win probability: "Does [candidate] prevail in the election?" — predominant structure
- Party control: "Which political party secures [legislative body]?"
- Vote share: "Does [party] capture above X% of ballots cast?"
- Timing: "Is the election outcome declared prior to [date]?"
- Policy: "Is [legislation] enacted within 90 days post-election?"
Proven Trading Strategies
Fading overreaction: Sensationalized reporting regarding debate missteps or revelations frequently causes disproportionate market swings. Contrarian positions typically revert toward fair value within several days.
Poll arbitrage: Unexpected polling movements that deviate from historical patterns often receive excessive market weight. Positions favoring regression toward historical norms have demonstrated consistent profitability.
Primary season: During nascent primary phases, leading contenders frequently trade at depressed probability levels. Momentum-driven path dependency remains systematically undervalued across markets.
Timing the news cycle: Unexpected late-campaign developments tend to produce exaggerated market corrections. Positioning ahead of subsequent stabilization proves advantageous.
