A moneyline bet on ATP Indian Wells is the most straightforward wager available: pick the player who will win the match outright, regardless of the score or number of sets. Unlike spread-based markets in team sports, there's no handicap applied — the selected player simply needs to advance. This simplicity makes moneyline betting the most popular market for tennis, but the odds can vary dramatically depending on the matchup. A top-five seed facing a qualifier in the early rounds might carry odds beyond -500, while later-round clashes between elite players often produce near pick'em pricing.
The moneyline market tends to be most valuable in the first few rounds at Indian Wells, where the 96-player draw creates asymmetric matchups that books sometimes misprice — particularly when lesser-known players carry strong hard-court form or favorable stylistic matchups. Bettors should monitor surface-specific stats, recent scheduling density, and desert heat conditions, which disproportionately affect certain playing styles. Regarding vig, tennis moneylines generally carry slightly higher margins than game spread or totals markets, especially in lopsided matchups where books widen the margin on heavy favorites. Comparing moneyline vig across sportsbooks becomes particularly worthwhile for these early-round mismatches where even small pricing differences meaningfully impact expected value.

Frequently Asked Questions
What is a moneyline bet?
A moneyline bet is the simplest form of sports wagering — you're picking which team will win the game outright, with no point spread involved. The odds reflect each team's implied probability of winning. Favorites have negative odds (e.g., -150) and underdogs have positive odds (e.g., +130).
Why does moneyline vig vary by matchup?
Moneyline vig is lowest on evenly matched games and highest on lopsided matchups. When a heavy favorite is -500, the book needs a wide margin on the underdog side to balance risk. Close games near pick'em (-110/-110) will always have the tightest vig.
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.
