What tennis can I bet on?
OVERDOG's tennis board runs year-round across the men's ATP Tour and the women's WTA Tour, from the week-to-week tournaments to the four Grand Slams — the same events the major books cover, priced as live exchange markets.
ATP Tour — men's tennis
The men's ATP Tour anchors the board through the season, led at the top of the rankings by world No. 1 Jannik Sinner, Carlos Alcaraz and Alexander Zverev, with Novak Djokovic still among the sport's most decorated names. The tour moves through the hard, clay and grass swings and the Masters 1000 events, and which matches are live shows on the board above.
WTA Tour — women's tennis
The women's WTA Tour runs alongside it, headed by world No. 1 Aryna Sabalenka, Elena Rybakina and Iga Świątek, with American Coco Gauff and the young Mirra Andreeva among the names that draw the heaviest markets. Women's singles carries the same bet types as the men's draw, and both tours feed the same Grand Slam fortnights, so a Wimbledon or US Open board mixes ATP and WTA matches side by side.
Grand Slams — the four majors
Tennis peaks four times a year at the majors: the Australian Open on Melbourne's hard courts in January, Roland Garros on the Paris clay across May and June, Wimbledon on London grass in June and July, and the US Open in New York through late summer. Alcaraz completed a career Grand Slam at the 2026 Australian Open and Zverev won his first major at Roland Garros, while Rybakina took the women's Australian Open title. The tournament-winner market for each major sits on its own futures page, linked from the board.
Tennis bet types
Here is what you can bet on OVERDOG's tennis board, from the match winner to a single set — each one a live market priced by the order book, not a fixed bookmaker line.
Match winner (moneyline)
The match winner, or moneyline, is the straight bet on which player takes the match. Tennis has no draw, so it is a two-way market — you back one side at the exchange price, and it settles on the completed result. A heavy favourite like Sinner or Sabalenka trades at a short price; an underdog pays longer, which is why many bettors pair the winner with a handicap.
Set and game handicaps (spreads)
A handicap levels an uneven match by spotting a player a head start or deficit. A set handicap of -1.5 asks the favourite to win by two clear sets, while +1.5 covers the underdog even if they lose in a deciding set. Game handicaps do the same across total games rather than sets — the exchange equivalent of the spread, and the most-bet way to back a lopsided matchup such as a top seed against a qualifier.
Total games (over/under)
Totals ask whether the two players' combined games finish over or under the line the market posts — a match total such as 22.5 games — regardless of who wins. A tight, serve-dominated matchup on grass tends to price over; a lopsided one that ends in quick straight sets prices under. Set totals narrow the same idea to the games inside a single set.
Set betting
Set betting prices the outcome inside the match rather than only the final winner: who takes the first set, who wins the second, and how the completed sets fall. Because a best-of-three or best-of-five match can swing set to set, these markets run deep on the board and trade independently of the match-winner price.
Tournament outright
Outright markets price a whole tournament rather than one match — the Wimbledon champion, the US Open winner, the year-end No. 1. Ahead of a major the shortest prices sit with the top seeds, but an outright stays live and re-prices every round as players advance or fall. The full winner market for each tournament sits on its own futures page, linked from the board above.
How to bet tennis with crypto on OVERDOG
Betting tennis with crypto on OVERDOG is crypto in, crypto out — the trading in between happens in a dollar-denominated unit:
1. Deposit a supported coin — Bitcoin, Ether, USDT, USDC, SOL or BNB — with no identity check. It converts to Polymarket's US-dollar stable unit on Polygon (about 1:1 with the dollar), the unit every position is priced, traded and settled in.
2. Pick a tennis market from the live board and buy shares in the outcome you want at the exchange price. The cost is a flat 1% OVERDOG fee plus Polymarket's own fees, shown together before you commit — there is no separate bookmaker margin and no promotions.
3. When the market resolves, each winning share redeems for one dollar on-chain, and you withdraw back to crypto. There are no cards or bank transfers.
Betting tennis on Polymarket with OVERDOG
OVERDOG is an access layer to the Polymarket exchange, not a bookmaker. When you bet tennis here, your order routes to Polymarket's real order book — you just get a betting-terminal experience over it, with crypto funding and no account gates.
No vig — real order-book odds
Every tennis outcome trades as a share that settles at one dollar if it happens and zero if it does not, so the price reads directly as the market's implied probability. Because those prices come from an order book rather than a bookmaker's spreadsheet, there is no margin — no vig — baked in. It describes the price only; it never implies a bet will win.
Winners are never limited
There is no house taking the other side of your bet, so there is no book to protect. Betting well never gets your account limited or closed — a structural contrast with sportsbooks, which routinely restrict sharp bettors.
No-KYC, your custody
You deposit and withdraw in crypto with no identity check, and you can export your wallet and withdraw anytime — we can't freeze you. Settlement runs on-chain via Polymarket on Polygon, where every resolution is publicly verifiable.
