How it works
Why prediction markets beat pundits
01
Real money, real stakes
Unlike rankings or pundit picks, prediction market traders put real money behind their views. Financial stakes filter out noise and produce more accurate probabilities than any expert panel.
02
CFTC-regulated exchanges
We source tennis data from Kalshi and Polymarket, both CFTC-regulated. No offshore markets, no legally ambiguous platforms — credible data you can cite in print.
03
Updated every 2 minutes
Probabilities shift after every set, retirement, and upset. Our systems pull fresh data every 2 minutes, around the clock, across every tour.
