Tennis Odds Across Every Prediction Market

ATP and WTA in one place - match winners, tournament futures and the Grand Slams, priced side by side from every platform quoting them.

How to Read Tennis Odds on Prediction Markets

Every outcome above trades as a contract that pays $1.00 if it happens and nothing if it does not, quoted in cents in between. That makes the price and the probability the same number: a player at 25¢ is the market saying 25%, with no vig to strip out first. Comparing that to a sportsbook's +300 is comparing a clean probability against one with margin folded in.

Each card shows every platform currently quoting that market, and the cheapest quote is highlighted - for an identical payoff it is simply the better entry. Tennis books run thinner than football or elections, and WTA books thinner than ATP, so cross-platform gaps here are wider and more frequent than anywhere else on the site.

Tennis Odds - Frequently Asked Questions

How do tennis odds work on a prediction market?+
Every outcome trades as a contract that pays $1.00 if it happens and nothing if it does not, priced in cents in between. The price is the probability: a player at 25¢ to win Wimbledon is the market saying 25%. Unlike a sportsbook line there is no vig to strip out - comparing a 25¢ contract to a sportsbook’s +300 is comparing a clean probability to one with margin folded in.
Does this page cover both ATP and WTA odds?+
Yes - this page carries every matched tennis market we track across both tours: ATP and WTA match winners, Grand Slam futures on the men’s and women’s draws, and tour-level tournament markets. Each card is labeled with its tour, and both filter into the same grid so you never have to pick one side of the sport to browse.
Where can I find Wimbledon and US Open odds on prediction markets?+
The Grand Slam futures on this page show each contender’s live price at every platform quoting them - Australian Open, Roland Garros, Wimbledon and the US Open, on both the ATP and WTA draws. Because these are live contract prices rather than a stored ranking, the favorite changes as the market does, and Slam futures reprice after every completed round.
Why do tennis prices differ between Polymarket and Kalshi?+
They are separate exchanges with separate order books - Kalshi is a CFTC-regulated US exchange trading in USD, Polymarket settles in USDC and draws global flow - so the same match routinely trades a few cents apart. Tennis books are thinner than NFL or elections, which makes those gaps wider and more frequent. The cheapest quote is highlighted on every card; for an identical payoff it is simply the better entry.
What makes tennis markets different from team-sport markets?+
No draws, no clock, and one player per side. A match contract has exactly two outcomes that must sum to ~100%, injuries and retirements resolve markets instantly rather than repricing them, and form travels with one person - a favorite’s bad day is not diluted across a roster. That makes tennis prices both cleaner to read and faster to move than team-sport equivalents.
How fast do tennis futures move during a tournament?+
Faster than any season-long future in team sports. A Slam future reprices after every round - each completed match removes contenders and shortens the survivors - and a single upset on a favorite’s half of the draw can move every remaining player’s price at once. The prices on this page refresh continuously through a tournament.
Are these sportsbook betting odds?+
No. These are prediction-market contract prices from exchanges like Kalshi (a CFTC-regulated US exchange) and Polymarket, where traders buy and sell outcome contracts against each other. Prices read as probabilities rather than American odds, and the conversion table on this page bridges the two formats.

How This Page Works

Prices come from each platform's own API and refresh at least once a minute. Contracts are quoted in cents and shown as implied probabilities, so a 25¢ price reads as 25%. The board covers every tennis market we carry across both tours; matches drop off once they are under way, and between tournaments an empty board means no live market rather than an error. Market availability and legality vary by platform and by state. This page is informational and is not betting or investment advice.
