Where the data comes from. Prices are 1-minute bid/ask candles from Kalshi's public API (ATP match and set-winner markets; NBA game-winner markets). NBA scores and shots come from ESPN's public play-by-play. Tennis: Jan–Sep 2026. NBA: 2025–26 season including playoffs.
How bets are priced. You buy at the ask 1–5 minutes after the moment, $10 per bet, minus Kalshi's taker fee (7% × contracts × price × (1 − price), rounded up to the cent). "Before the match" tennis prices are the midpoint plus 1¢, because only midpoints were saved for that moment.
Research, not betting advice. Past prices don't guarantee future results, and small samples can look profitable by luck.
