A free Oddpool account gives you access to 40+ event dashboards with cross-venue odds, the prediction market search engine, historical charts, and basic whale trade data. No credit card required.

Is $30/month worth it?

Pro users find hundreds of arbitrage opportunities every week. A single arb trade can return more than the cost of a monthly subscription. If you actively trade on Kalshi or Polymarket, the scanner pays for itself quickly.
