DraftKings leads with 2.74% vig (A), followed by Hard Rock Bet at 3.21%. The spread between #1 and #14 is 5.78% — book choice matters significantly for ATP French Open.

The French Open stands apart from every other tennis major for one fundamental reason: clay. The slow, high-bouncing surface at Roland Garros dramatically reshapes the competitive hierarchy, making specialists out of players who struggle elsewhere and neutralizing the weapons of grass and hard-court dominators. For bettors, this creates exploitable inefficiencies — the market often prices players based on overall ATP rankings rather than clay-specific form. Match duration is another key variable; best-of-five-set matches on clay produce some of the longest contests in tennis, which increases the influence of fitness, mental endurance, and in-play betting opportunities. Market depth at the French Open is among the best in tennis, with sportsbooks offering extensive set betting, game handicaps, total games, and first-set winner lines alongside standard moneylines.

Vigorish on French Open match markets tends to be relatively tight on the main draw, particularly from the quarterfinals onward, where high-profile matchups attract significant handle and force books to compete on price. Early-round matches and qualifying rounds carry wider margins, sometimes exceeding 6-8% on moneylines, as books price in uncertainty and lower liquidity. Prop markets and set-correct-score lines consistently carry higher vig regardless of round. Bettors comparing odds across multiple books during the tournament's second week will typically find the sharpest pricing, as competition among sportsbooks intensifies around marquee semifinal and final matchups.

The clay season builds through April and May — with Monte Carlo, Barcelona, Madrid, and Rome serving as critical form indicators — before culminating at Roland Garros in late May and early June. Bettors who track clay-season results closely gain a significant edge, as recent surface-specific form is the single most predictive factor for French Open outcomes. Weather plays an outsized role; rain delays disrupt rhythm and can shift momentum dramatically, while the retractable roof on Court Philippe-Chatrier has added a new variable since 2020, effectively creating indoor-like conditions that favor bigger hitters. Injury monitoring is essential, as the physical toll of the clay swing means players frequently arrive at Roland Garros managing fatigue, and withdrawal or retirement risk is higher than at other Slams.

Frequently Asked Questions

Which sportsbook has the lowest vig for ATP French Open?

DraftKings currently has the lowest average vig for ATP French Open at 2.74%, earning a grade of A.

How do sportsbook odds compare for ATP French Open?

We compare 14 sportsbooks for ATP French Open. The vig ranges from 2.74% (DraftKings) to 8.52% (Fliff).

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.
