A Tennis prediction market lets traders buy and sell shares in real-world Tennis outcomes for matchups like Busan: Yi Zhou vs Pavel Kotov and Madrid Open: Hailey Baptiste vs Mirra Andreeva. Each share is priced between 0¢ and 100¢, and the price reflects the market's implied probability that the outcome occurs.

Polymarket uses probability-based pricing rather than traditional moneyline or spread odds. A Tennis contract priced between 0¢ and 100¢ reflects the market's implied probability of that outcome. Prices update continuously as traders incorporate new information — injuries, weather, sportsbook movement, and in-play developments.

The most-traded Tennis markets at the moment include Busan: Yi Zhou vs Pavel Kotov, Madrid Open: Hailey Baptiste vs Mirra Andreeva, and Saint-Malo: Whitney Osuigwe vs Viktorija Golubic. Trading volume reflects how much real money is flowing through each market and is a useful signal of where consensus is forming.

New Tennis markets are typically listed ahead of major fixtures, tournaments, and seasons. Markets are added as schedules are finalized and resolved once outcomes are official.

There are 59 live Tennis prediction markets, including ones for ATP and WTA, on Polymarket.

Polymarket Tennis prices reflect the consensus of traders putting real money at risk on Tennis outcomes — what research often calls the "wisdom of crowds" with skin in the game.

On Polymarket, Tennis predictions aren't tips, picks, or guarantees — they're the live, market-driven view of how likely each Tennis outcome is. Tennis odds are shown as prices between 0¢ and 100¢, and that price is the implied probability of the outcome. So a Tennis prediction is the question being asked ("who wins?"), and the Tennis odds are the real-time, real-money answer the market is giving.
