01 · Overview

What is Oddpool?

Oddpool combines Kalshi and Polymarket search, matched-event dashboards, arbitrage scanning, whale flow, historical order books, and normalized APIs. Best for: Researchers, quants, and traders comparing equivalent markets or building with cross-venue data. Less suitable for: Users expecting guaranteed arbitrage or direct automated execution. Key limitations: Matched markets can have different rules and settlement sources. Apparent price gaps may disappear after fees, spread, liquidity, and execution timing.
