Sharp prices, tennis context, one alert
We watch every price
Pinnacle, Kalshi and Polymarket tennis markets are recorded every few seconds — ATP, WTA and Challenger, from the opening price to the start.
We flag what matters
A move only becomes an alert when it's big and fast — with surface Elo, form and serve stats attached so you can judge it.
We grade every alert
Each alert is checked against the closing price and the result. Weekly results are posted in public — good weeks and bad.
Five alerts at launch
Every alert type is measured. Types that don't beat the closing price get retuned or removed — and we say so.
Price drop FREE
Pinnacle's probability for a player rises 3+ points within 15 minutes.
Big move PRO
6+ points, or a move while Pinnacle raises its stake limit — the strongest signals.
Late move PRO
3+ points in the last hour before the match, often driven by fitness news.
Prediction market behind PRO
Kalshi or Polymarket priced below Pinnacle's fair value after fees, with depth to trade.
New market opened FREE
New Kalshi or Polymarket tennis markets, shown next to Pinnacle's fair price.
Weekly results FREE
Every alert type's closing-line value, hit rate and profit — every Monday.
Judged by the closing price, not by win rate
Win rate is easy to fake — back heavy favourites and you'll "win" most of the time. We publish closing-line value and profit at the alerted price, for every alert.
How we grade an alert
Say an alert flags a player at 1.62. If Pinnacle closes at 1.54, the alert beat the close by 3.2 points — whatever the result.
Over hundreds of alerts, beating the close is the most reliable sign of a real edge. Results and profit are shown alongside it.

Questions
Is this a tipster service?
No. We show where sharp prices are moving and the tennis context behind it. What you do with that is your decision — and every alert's result is published, good or bad. Nothing here is betting advice.
Why Pinnacle?
Pinnacle takes large bets at low margins, so its prices are widely treated as the market's best estimate. When it moves, other bookmakers and prediction markets often follow.
What are Kalshi and Polymarket?
Prediction markets where people trade yes/no contracts on match winners. Prices are in cents — 63¢ means about a 63% implied chance. We show them next to Pinnacle so you can see when they lag behind. Availability depends on where you live.
Which matches do you cover?
ATP, WTA and Challenger singles at launch. ITF and in-play alerts come later.
Why is the free channel delayed?
Fast alerts lose value when everyone acts on them at once. The 10-minute delay keeps the free channel useful for learning and tracking, while Pro members get the moves live.
Do you take bets or hold money?
No. TennisOdds is an information service. We are not a bookmaker, exchange or broker, and we never hold users' funds.
