How Election Markets Resolve
Resolution mechanisms depend on market jurisdiction:
- 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
Following a definitive outcome, most contracts settle in hours, with USDC distributions reaching Polygon participants within moments of final settlement.
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: Momentary swings triggered by debate stumbles or revelations frequently exceed their fundamental impact. Contrarian positions typically stabilise within several days as markets digest information.
Poll arbitrage: Outlier polling results often receive disproportionate weighting by market participants. Positions favoring regression toward historical averages have demonstrated consistent profitability.
Primary season: During early primary contests, leading contenders' odds frequently underestimate their structural advantages. Momentum-driven mispricing persists throughout the selection phase.
Timing the news cycle: Late-campaign surprises generate excessive market corrections. Establishing positions before normalisation occurs captures mean-reversion gains.
