Volatility Arbitrage in Prediction Markets: Why Political Favorites Above 60¢ Are Systematically Underconfident

A binary contract at price p has variance p(1-p). Le 2026 (292M trades) finds political markets underconfident at slopes 0.93-1.83 — meaning a 70¢ contract corresponds to a true probability near 83%. Four systematic vol-arb trades follow from the calibration evidence.

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
