WTA Wimbledon presents a distinctive betting landscape shaped by the unique demands of grass-court tennis. The surface produces faster, lower-bouncing rallies that reward aggressive serving and net play — attributes that don't always correlate with a player's overall WTA ranking. This creates genuine value opportunities for bettors who understand grass-court form, as oddsmakers often lean heavily on season-long results when setting early-round lines. Market depth is solid for a Grand Slam, with most books offering match winners, set betting, total games, handicap lines, and an array of prop markets. However, liquidity and market variety thin out considerably in the early rounds for lower-profile matchups, which is precisely where the sharpest edges tend to exist.
Vigorish on WTA Wimbledon match lines tends to be tighter than regular WTA tour events but can still vary meaningfully across sportsbooks, particularly in early rounds and qualifying matches where books have less confidence in their pricing. For marquee quarterfinal and semifinal matchups, competition among bookmakers drives margins down, often into the 3-5% range on match-winner markets. Earlier rounds and less prominent courts can see vig creep toward 6-8% or higher, making line shopping especially important during the first week of the tournament. Set betting and game totals typically carry wider margins than moneylines across the board.
The tournament runs over two weeks in late June and early July, and odds are most competitive once the draw is released and multiple books have had time to sharpen their numbers. Key factors that move WTA Wimbledon lines include grass-court preparation events like Eastbourne and Birmingham — a player's recent results on grass carry far more predictive weight than clay-court form from Roland Garros just weeks earlier. Weather delays and the retractable roof on Centre Court can alter match dynamics, particularly for players who thrive in open-air conditions. Injury monitoring is critical, as the transition from clay to grass in a compressed window frequently produces soft-tissue issues. Head-to-head records on grass, return-of-serve efficiency on fast surfaces, and first-serve winning percentage are the statistical pillars that most reliably separate mispriced lines from accurate ones.

Frequently Asked Questions
Which sportsbook has the lowest WTA Wimbledon vig?
Pinnacle currently has the lowest vig at 2.78%, earning a grade of A.
What is vig (vigorish) in sports betting?
Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.
How often is this data updated?
We pull fresh odds from The Odds API three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.
How is the vig grade calculated?
Each sportsbook is graded on a letter scale based on average vig: A+ (under 2%) is exceptional, A (2–3%) is excellent, B+ (3–4%) is above average, B (4–5%) is the industry standard, C (5–6%) is below average, and D (above 6%) indicates high-juice markets.
Why does lower vig matter for bettors?
Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.
What sportsbooks do you track?
We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnySports). Data comes from The Odds API, which aggregates real-time lines from licensed sources.
How We Calculate These Numbers
- Data Source
- All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
- Update Frequency
- We pull a fresh snapshot of every tracked market three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
- Vig Calculation
- Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
- Per-Market Breakdown
- We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
- Grading Scale
- Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exchange-level pricing. A (2–3%) is very competitive. B+ (3–4%) is above average. B (4–5%) is the industry standard — a -110/-110 line is 4.76%. C+ (5–6%) is slightly below average. C (6–7%) is below average. D (7–8%) is high vig. D− (8–10%) is very high vig. F (10%+) is predatory pricing. See the full Vig Index Methodology for formulas, worked examples, and known limitations.
- Trend Tracking
- We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
