How Election Markets Resolve
Resolution mechanisms differ according to market type:

- UK elections: BBC official declaration or Electoral Commission pronouncement
- EU elections: Formal announcement from the appropriate electoral body
- Disputed outcomes: UMA oracle community vote following a 2-hour challenge period
Following a decisive outcome, most markets settle within hours, with USDC distributions reaching Polygon addresses moments after final resolution.
Types of Election Markets
- Win probability: "Will [candidate] win the election?" — the predominant market structure
- Party control: "Which party will govern [legislative body]?"
- Vote share: "Will [party] achieve more than X% of votes cast?"
- Timing: "Will the election outcome be declared by [date]?"
- Policy: "Will [policy initiative] be enacted within 90 days following the election?"
Proven Trading Strategies
Fading overreaction: Intense media attention to a debate stumble or political controversy frequently drives disproportionate market swings. Contrarian positions typically gravitate back toward fair value within several days.
Poll arbitrage: When polling data reveals a dramatic shift appearing statistically anomalous, market participants often amplify this movement excessively. Positioning for regression toward historical norms has demonstrated consistent returns.
Primary season: During the opening phases of primary contests, leading candidates' win probabilities are frequently underestimated. The self-reinforcing nature of campaign momentum remains systematically undervalued.
Timing the news cycle: Late-breaking revelations tend to push markets into extreme positions. Establishing positions ahead of the inevitable rebalancing proves advantageous.
