How Election Markets Resolve
Resolution mechanisms depend on the specific jurisdiction:
- US elections: Associated Press announcement serves as the authoritative resolution benchmark
- UK elections: BBC official declaration or Electoral Commission pronouncement
- EU elections: Relevant national electoral authority's official statement
- Contested results: UMA oracle governance vote following a 2-hour challenge period
Settlement typically occurs within hours once a definitive outcome emerges, with USDC transfers completing on Polygon within minutes thereafter.
Types of Election Markets
- Win probability: "Will [candidate] win the election?" — the predominant category
- Party control: "Which party will control [legislative body]?"
- Vote share: "Will [party] exceed X% of votes cast?"
- Timing: "Will the election outcome be called before [date]?"
- Policy: "Will [legislation] become law within 90 days post-election?"
Proven Trading Strategies
Contrarian positioning after overreaction: Journalistic focus on a candidate misstep or controversy typically causes disproportionate market moves initially. Positions opposing these swings frequently converge back toward fair value within several days.
Poll divergence trading: Outlier polling results often receive excessive weight in market pricing. Historical evidence suggests betting on regression toward the mean generates consistent returns.
Early primary dynamics: During the opening stages of primary contests, leading candidates frequently trade below their true probability. Momentum's path-dependent nature remains systematically undervalued.
News cycle positioning: Late-breaking revelations tend to push markets beyond rational equilibrium. Establishing positions ahead of the inevitable correction proves rewarding.
