KashRock launches esports consensus odds API aggregating Kalshi, Polymarket, and Thunderpick
KashRock has launched an esports consensus odds API that aggregates pricing from Kalshi, Polymarket, and Thunderpick. The service covers Counter-Strike 2, League of Legends, Valorant, and Dota, converting each source's odds into a single de-vigged fair probability. Access to the API is gated. A separate offering pulls Polymarket esports match and map markets as normalized probabilities and odds, combining crowd-priced mainlines with sportsbook data.
The API merges CFTC-regulated event-contract prices with sportsbook and crypto-exchange odds for the first time at scale. That fusion matters for traders who price esports derivatives: they can now quote off a single consensus curve instead of polling three separate venues. Kalshi and Polymarket, the integration treats their markets as interchangeable inputs alongside a traditional sportsbook, diluting any platform-specific moat.
Thunderpick gains institutional visibility it lacks on its own. The risk is sourcing quality: if Thunderpick's crypto-native liquidity is thin or Kalshi's esports markets are shallow, the blended fair probability veers wrong and erodes trust. Developers building on the API now bear the model risk KashRock abstracts.
