For every tennis match tracked, OddScore turns market data into a structured reading, refreshed every 15 minutes and easy to understand.
OddScore collects and compares odds from several sportsbooks on the two outcomes of the match.
Odds are adjusted to estimate market probabilities without the sportsbooks' commercial margin.
Direction, size and consistency of the variations observed before the match, refreshed every 15 minutes.
An AI reading arrives around 25 minutes before the match starts, summarized in a 0 to 100 signal.
OddScore analyzes the pre-match winner market, across both ATP and WTA draws. To go further, read our page on tennis odds explained by OddScore.
Before picking a bet, our tennis prediction guide walks through the analysis method.
Tennis has no draw: OddScore analyzes the only two possible outcomes, a win for the first player or a win for the second.
On a two-outcome market, the sportsbook margin weighs directly on every price. OddScore strips it out to estimate the probability the market actually expects.
OddScore analyzes matches from the four Grand Slams as well as the main tournaments on the ATP and WTA tours.
OddScore does not try to announce the winner of a tennis match with certainty. The tool analyzes odds movements and the information available before the match to explain what the market is pricing in.
Check market movements, estimated probabilities and the latest AI readings on the tennis matches tracked by OddScore.
A tennis odds analysis means observing how the odds of several sportsbooks move before a match, then turning those movements into readable probabilities and signals. OddScore compares those odds, removes the sportsbook margin and computes a 0 to 100 signal for every tennis match tracked.
Odds move with staking volume, last-minute information (withdrawals, form, how long the previous match lasted) and the sportsbooks' own adjustments. OddScore tracks these variations continuously to spot the most meaningful movements.
OddScore compares the odds of several sportsbooks, removes their commercial margin to estimate market probabilities, then measures the direction, size and consistency of the movements observed before each tennis match.
The match winner market, which has only two outcomes since there is no draw in tennis. Games and sets markets are not covered: their pricing is too uneven from one sportsbook to another to support a reliable comparison.
OddScore covers the four Grand Slams — Australian Open, Roland-Garros, Wimbledon and US Open — as well as the main Masters 1000, ATP 500 and WTA 500 events on the calendar.
Yes. Men's and women's draws are treated the same way, with the same markets and the same 0 to 100 signal.
OddScore generates one AI reading per tennis match, around 25 minutes before the match starts, to factor in the most recent information.
A tournament publishes an order of play, not a firm time: each match starts when the previous one ends on the same court. OddScore follows these shifts and adjusts both the displayed time and the schedule of its AI readings.
The signal combines the gap between the estimated market probability (margin-free odds) and a reference probability, dampened by the intensity and consistency of the observed movement. The higher the signal, the more pronounced the market movement.
No. OddScore gives no recommended bet and no exact score. The tool analyzes odds movements and market probabilities to explain what is happening before a match, not to predict its result.
Yes. Creating an account is free and needs no credit card. You can open 5 upcoming matches with their AI analysis; after that, values and charts stay locked until you go Pro.
