Election forecasting represents Polymarket's core offering. During significant electoral periods, individual contracts frequently surpass $50 million in traded value. This guide covers essential information for participants seeking to engage with election markets profitably.
How Election Markets Resolve
Resolution mechanisms depend on the specific market:
- US elections: The Associated Press race determination serves as the authoritative resolution metric
- UK elections: BBC's official declaration or Electoral Commission announcement
- EU elections: Formal proclamation from the relevant national electoral body
- Contested results: UMA protocol enables token holders to adjudicate following a 2-hour challenge period
Settlement typically occurs within hours once a definitive outcome emerges, with USDC distributions reaching Polygon participants in mere minutes post-resolution.
Types of Election Markets
- Win probability: "Will [candidate] win the election?" — the predominant contract structure
- Party control: "Which party will command [chamber]?"
- Vote share: "Will [party] capture more than X% of the vote?"
- Timing: "Will the election be called before [date]?"
- Policy: "Will [policy] be enacted within 90 days of the election?"
Proven Trading Strategies
Fading overreaction: Journalistic attention to a candidate misstep or controversy frequently produces disproportionate price swings. Contrarian positions typically revert toward fair value within several days.
Poll arbitrage: Surveys indicating dramatic shifts that appear anomalous tend to receive excessive weighting by market participants. Positioning for regression toward historical averages has demonstrated consistent profitability.
Primary season: During the early stages of primary contests, leading candidates' win odds tend to be suppressed. The self-reinforcing nature of campaign momentum remains systematically undervalued.
Timing the news cycle: Late-campaign surprises typically induce excessive market corrections. Establishing positions ahead of the inevitable rebalancing proves advantageous.
