DraftKings leads with 3.95% vig (B+), followed by FanDuel at 4.78%. The spread between #1 and #9 is 4.82% — book choice matters significantly for ATP Indian Wells.
The BNP Paribas Open at Indian Wells is one of the most heavily bet tennis events on the calendar, sitting just below the Grand Slams in prestige and market depth. As a Masters 1000 event, it draws virtually every top player and runs across nearly two weeks in early March, giving bettors a dense schedule of matches with robust moneyline, set spread, and game total markets. Tennis betting at this level offers a unique dynamic: the sport's sequential scoring structure means momentum shifts are constant, and a single break of serve can dramatically alter match trajectory. This creates opportunities for sharp bettors who understand surface-specific performance and how players handle the unique conditions of the Southern California desert.
Vig on ATP Indian Wells matches tends to be tighter than at lower-tier ATP events but slightly wider than what bettors find at Grand Slams. The high public interest and substantial betting volume on early-round matches featuring top seeds forces sportsbooks to compete on price, particularly on marquee matchups. However, margins can widen noticeably in first-round and second-round matches involving qualifiers or lower-ranked players, where books have less certainty in their models and lower handle to justify razor-thin edges. Comparing vig across books becomes especially valuable in these lesser-followed matches, where the spread between the sharpest and softest lines can be significant.
Conditions at Indian Wells are a critical factor that casual bettors often underestimate. The tournament is played on outdoor hardcourts at elevation in a desert climate, where the ball flies faster and bounces higher than at sea-level hard-court events. Big servers and aggressive baseliners tend to thrive, while grinders who rely on heavy topspin and extended rallies can struggle. Daytime sessions feature intense heat and sun that can sap energy, particularly in early rounds when players are still adjusting, while evening sessions play noticeably slower in cooler temperatures. Scheduling — whether a player draws a day or night match — can meaningfully affect outcomes. Additionally, the tournament's position in early March means players are still building form after the Australian swing, making recent results and fitness signals especially important when evaluating odds.

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 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.
