The ATP Monte-Carlo Masters operates on a unique timeline as the first major clay court event of the European season, typically held in mid-April each year. Unlike other ATP Masters 1000 events, this tournament marks the beginning of the crucial clay court swing that extends through the French Open in early June. Futures markets for the Monte-Carlo Masters generally open in late February following the conclusion of the hard court season, with early outright winner odds reflecting players' historical clay court form and their anticipated preparation schedules. The tournament's positioning as a warm-up event for Roland Garros creates distinct betting dynamics, as many top players use Monte-Carlo to test their clay court fitness rather than prioritize the title.

Off-season betting opportunities for Monte-Carlo center primarily on outright winner futures and set betting props, with particular attention to clay court specialists who may offer exceptional value. Head-to-head matchup futures become available once the draw is released in early April, while first-round elimination props gain traction given the tournament's reputation for early upsets on the slower surface. The clay court transition creates unique wagering angles, particularly for players returning from injury or those with historically strong Monte-Carlo records like Rafael Nadal's unprecedented dominance at the venue.

Vig patterns for Monte-Carlo futures typically tighten significantly once the Miami Open concludes in late March, as books gain clarity on player form and fitness levels entering the clay season. The biggest odds movements historically occur following the Indian Wells and Miami Masters results, which provide the final hard court form indicators before the surface change. Withdrawal announcements create substantial line movement, particularly when involving clay court favorites, while early-season injury reports and practice session observations from Monte-Carlo can shift odds dramatically in the days preceding the tournament.

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.
