The French Open stands apart from every other tennis major for bettors because clay-court tennis fundamentally reshapes the competitive landscape. The slow surface extends rallies, reduces the impact of big serves, and historically produces longer matches with more breaks of service. This means favorites face more volatility than on faster surfaces like grass or hard court, and live betting markets become particularly dynamic as momentum swings are common across five-set matches. Market depth at Roland Garros is exceptional — major sportsbooks offer match winners, set betting, game handicaps, total games, correct score, and increasingly granular prop markets on aces, double faults, and break points. The two-week tournament structure, combined with a 128-player draw, creates a high volume of betting opportunities from early rounds through the final.

Vig on French Open matches varies significantly depending on the round and the profile of the matchup. Early-round contests featuring lesser-known players or lopsided matchups tend to carry wider margins, sometimes exceeding 5-6%, as books price in uncertainty and limit their exposure. By the quarterfinals and beyond, where public interest and sharp money converge, margins tighten considerably — often dropping to 2-4% on match-winner markets at the most competitive books. Totals and handicap lines typically carry slightly wider margins than moneylines across all rounds, making it essential to compare across multiple sportsbooks.

The clay-court season builds through April and May, with tournaments in Monte Carlo, Barcelona, Madrid, and Rome serving as critical form indicators before Roland Garros begins in late May. Bettors who track performance across this swing gain a significant informational edge, particularly for identifying players whose games translate well to slow clay versus those merely riding ranking momentum from hard-court results. Surface-specific win rates, head-to-head records on clay, fatigue from a congested schedule, and Paris weather — where rain delays and cool, heavy conditions can neutralize certain playing styles — are all essential variables. Rafael Nadal's historic dominance reshaped this market for years, but the post-Nadal era has introduced more competitive odds and genuine uncertainty deeper into the draw.

Frequently Asked Questions

What are the best ATP French Open lines today?

The table below shows which sportsbook has the best available price on each side of every upcoming ATP French Open event. Line shopping across multiple books can save you 1–3% per bet compared to sticking with a single sportsbook.

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 every hour, on the hour (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 average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.

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, BetAnything). 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 every hour, on the hour (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.
