Kalshi and Polymarket price the same games this board reads β as tradeable markets. Their quotes beside the sportsbook de-vig fair line. Market facts only; a gap is context, never a directive. Exchange prices are kept out of the fair line, best price, edge and CLV math.
Prediction-market and exchange prices are displayed for comparison only β they are tagged by kind, never blended into the fair line or any graded number, and nothing here links to any venue. Kalshi and Polymarket return no player props through this feed; this is a teams-and-games lens.
