Prediction market arbitrage data
Cross-venue price gaps can look like arbitrage, but fees, settlement rules and liquidity often remove them. Good data shows all of these.
What the data must include
- Prices from each venue at the same time.
- Order book depth, not just last price.
- Each venue’s fees.
- Whether the markets settle on exactly the same outcome.
Use the round-trip cost estimator before assuming a gap is profitable.
