Two Different Endings, Two Different Settlement Rules
Tennis is one of the few sports where a match can end without a normal result — a player retires mid-match, unable to continue, or withdraws before a ball is even struck and the match is recorded as a walkover. Both outcomes change how a bet settles, and they don’t settle the same way as each other. Knowing the mechanics behind each before you back a player carrying any injury doubt is worth more than any single price on the market.
Retirement: The Match Was Underway
A retirement happens once play has started. A player stops, usually through injury, illness or exhaustion, and the match is awarded to the opponent who remained on court. For a match winner or outright bet, that’s a clean result: the player left standing is the winner, and the bet settles accordingly the moment the retirement is confirmed.
Markets tied to the score are where it gets more specific. Set betting, game handicaps, set handicaps and total games all depend on how much of the match was actually played, and most operators only grade those markets if a full set had been completed at the point of retirement. Retire mid-set, and those markets are typically voided rather than settled on a partial score, because there’s no completed set to grade the bet against. This threshold — one full set completed — is the most common rule, but it isn’t universal, and some tournaments and operators apply the settlement at a different point, such as the moment a point is struck after a change of ends. Our Tennis Bet Types Explained page covers how each market is built before you factor retirement into it.
Walkover: Nothing Was Actually Played
A walkover is a different situation entirely. It happens before the match starts — a player withdraws in advance, often from an injury carried over from an earlier round or a late scheduling conflict — so no games, sets or points are contested at all. Because there’s genuinely nothing to grade, most operators void every market on a walkover match, including the match winner bet, rather than settling anything. An outright bet on a player who receives a walkover into the next round generally stays alive, since the outright is decided by the tournament result, not by any single match’s markets; a player eliminated by walkover has their outright bet settled as a loss the same as any other elimination.
Why the Rule Isn’t the Same Everywhere
Retirement and walkover settlement isn’t governed by one universal standard. The rule a specific market settles under depends on both the tournament’s governing body — the ATP, the WTA and each Grand Slam run their own rulebooks — and on the individual sportsbook’s own bet rules for that market. Some apply the one-full-set standard described above across the board; others tie settlement to whether the match has reached a specific point count or game count rather than a completed set. This is exactly the kind of detail that’s easy to assume rather than check, and it’s the single most common source of a bet result that looks wrong until you read the fine print.
What to Check Before You Bet a Player With an Injury Doubt
If a player is carrying a niggle, coming back from injury, or has a history of retiring mid-match, it’s worth reading the specific market’s rules before betting anything beyond a straight match winner. That’s true whether you’re looking at set betting, a games handicap or a total games line — each one can carry a slightly different retirement clause even within the same match. Rexbet publishes its own tennis betting rules covering exactly this scenario for every market it offers, and that page — not a general assumption based on how a different sport handles the same situation — is the accurate source for how a specific bet will settle.
The Practical Takeaway
A retirement usually settles the match winner and outright markets cleanly in the surviving player’s favour, but voids or partially settles score-dependent markets depending on how far the match got. A walkover almost always voids everything, since nothing was played. Our Tennis Betting Guide covers the rest of what to check before placing a first bet, including how to read a matchup for exactly this kind of risk before it turns into a voided ticket.
