Pinnacle leads with 0.63% vig (A+), followed by DraftKings at 1.53%. The spread between #1 and #9 is 6.96% — book choice matters significantly for ATP Miami Open.

The ATP Miami Open, staged annually at Hard Rock Stadium, stands as one of the premier Masters 1000 events on the tennis calendar and offers a deep, liquid betting market. Tennis betting in general rewards sharp analysis because of its individual nature — there are no teammates to mask a player's form or fatigue. The Miami Open amplifies this dynamic with its large 96-player draw, which creates early-round matchups between elite seeds and qualifiers or lower-ranked opponents where oddsmakers must price in significant skill gaps. Moneyline, set spread, game totals, and an expanding array of in-play prop markets give bettors multiple angles. The hard-court surface tends to favor big servers and aggressive baseliners, which makes scoring patterns somewhat more predictable than on clay, though Miami's humid conditions can introduce volatility.

Vig on Miami Open markets generally falls in line with other high-profile ATP events, meaning the most popular matches — particularly from the quarterfinals onward — tend to carry tighter margins as sportsbooks compete aggressively for handle. Early-round matches with lesser-known qualifiers often see wider margins because books have less reliable data and lower betting volume, giving them less incentive to sharpen their lines. Bettors comparing odds across multiple books during the first few rounds can frequently find meaningful discrepancies, especially on totals and set spreads where each shop may model differently.

The tournament typically runs in late March, immediately following the Indian Wells Masters, which creates a critical scheduling factor. Players arriving from the California desert may be dealing with accumulated fatigue, minor injuries, or the mental hangover of a deep run — or conversely, they may carry sharp match fitness and confidence. Miami's oppressive heat and humidity are genuine x-factors that disproportionately affect European players less accustomed to those conditions, and afternoon matches tend to play differently than evening sessions under lights. Surface speed, which has varied slightly across venue changes, and each player's historical performance in South Florida are essential inputs. Bettors who track retirement rates, which spike in humid Masters events, can also find value in adjusted totals and live markets.

What is the Miami Open?

The Miami Open is an ATP Masters 1000 and WTA 1000 tennis tournament held annually in March-April at Hard Rock Stadium in Miami Gardens, Florida. Along with Indian Wells, it forms the "Sunshine Double" — two of the biggest tennis events outside the Grand Slams.

How does Miami Open vig compare to Grand Slams?

Miami Open vig is generally slightly higher than Grand Slam vig because the tournament attracts less overall betting volume. However, matches featuring top-10 players still see competitive pricing at sharp sportsbooks.

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.
