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.

The ATP Wimbledon Championship operates within a compressed annual window, with the tournament taking place during the first two weeks of July each year. Unlike traditional sports seasons, Wimbledon functions as a standalone major event within the broader ATP calendar, with qualifying rounds beginning in late June and the main draw concluding by mid-July. Sportsbooks typically release initial Wimbledon futures odds in late January following the Australian Open, with markets fully established by March. The grass court season leading up to Wimbledon runs from mid-June through early July, providing crucial form indicators that significantly impact pre-tournament odds.

Off-season betting opportunities for Wimbledon center heavily on outright winner markets, with books offering odds on men's singles champion, finalist combinations, and set betting props months in advance. Quarter-specific futures become available closer to the draw ceremony, while head-to-head matchup markets for potential early-round encounters often appear in May. Books also offer novelty markets such as "British player to reach furthest" and "youngest/oldest player to reach specific rounds." The unique grass court surface creates distinct value opportunities, as players' hard court and clay court form from earlier in the year may not accurately reflect their Wimbledon potential.

Vig patterns for Wimbledon futures typically start loose in the winter months, with books offering more generous odds on longshot contenders before the European clay court season begins. The sharpest lines emerge during the French Open in late May and early June, when books have clearer pictures of player form and fitness. Historical data shows the most significant odds movements occur following grass court warm-up tournaments in Stuttgart, Halle, and Queen's Club, where players reveal their surface adaptation. Injury withdrawals during these preparatory events create the largest market disruptions, particularly when they involve top-10 players who were heavily backed in early markets.

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.
