Sportsbooks show the betting market. Polymarket shows the belief market.
Kam separates sportsbook odds from prediction-market prices, then explains where the markets agree, disagree, or need more verification.

Kam separates sportsbook odds from prediction-market prices. It does not treat one source as a substitute for the other.
What each market tells you
| Market | What Kam checks |
|---|---|
| Sportsbook context | Spreads, totals, moneylines, book movement, consensus, and freshness. |
| Prediction-market context | Polymarket game markets, futures, probabilities, liquidity, volume, and disagreement. |
| Market Shape | Probability gaps, stale signals, thin liquidity, source disagreement, and next checks. |
Important caveat
Kam should never treat Polymarket as sportsbook odds or claim prediction-market prices are always sharper. It explains the gap and tells you what to verify.
Useful question
Ask: Where do sportsbooks and Polymarket disagree, is liquidity strong enough to care, and what would make the gap actionable?
Data availability is not one state.
Learn how Kam separates source data, projection readiness, active response scope, rendered output, stale data, and blocked claims.
An empty board does not always mean no game exists.
A quiet board can mean no edge, missing coverage, delayed data, stale context, or simply no material move.
