The BNP Paribas Open at Indian Wells stands as one of the most compelling betting events on the ATP calendar. As a Masters 1000 tournament, it draws nearly the full top-100 field, creating a deep and liquid betting market across moneylines, set spreads, game totals, and an expanding array of prop options. The 96-player draw means the first few rounds often feature stark mismatches between seeds and qualifiers, but the best-of-three-set format keeps volatility high — upsets happen with enough regularity to reward bettors who understand surface-specific form and early-round dynamics on the hard courts of the Southern California desert.
Vig on ATP Indian Wells matches tends to be tighter than at lower-tier ATP events, largely because of the tournament's prestige and the volume of sharp action it attracts. Sportsbooks compete more aggressively on marquee matches involving top-10 players, where margins can drop to the 3-5% range on moneylines. However, early-round matches featuring qualifiers or lower-ranked players often carry wider margins — sometimes 6-8% or more — because books have less confidence in their lines and fewer data points to work with. Comparing vig across books during these rounds is where the most value tends to surface.
Indian Wells typically runs in early to mid-March, positioning it as a pivotal hardcourt swing after the Australian Open and the brief indoor/clay transition period. Player fitness is a major factor at this stage of the season — some competitors are still rounding into form, while others may be managing nagging injuries from the Australian summer. The dry desert heat and low humidity at the Indian Wells Tennis Garden produce fast conditions with high bounces, favoring big servers and aggressive baseliners. Wind can also be a significant variable, particularly in afternoon sessions, disrupting rhythm players and creating over/under value on game totals. Bettors who track how specific players perform in arid, windy conditions hold a genuine edge over the market.

Frequently Asked Questions
Which sportsbook has the lowest ATP Indian Wells vig?
DraftKings currently has the lowest vig at 3.95%, earning a grade of B+.
What is the Indian Wells tennis tournament?
The BNP Paribas Open at Indian Wells is an ATP Masters 1000 and WTA 1000 event held annually in March in Indian Wells, California. It is often called the "fifth Grand Slam" due to its prestige and large draw size. The tournament attracts the world's top players.
How does tennis vig compare to team sports?
Tennis moneyline vig varies by matchup. Close matches between top-ranked players attract significant betting volume and competitive vig. Lopsided first-round matchups with heavy favorites carry higher vig because sportsbooks widen margins on one-sided contests.
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.
