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.

Copa América operates on a unique tournament cycle that differs significantly from traditional soccer leagues, with the competition held every four years (though CONMEBOL has experimented with shorter intervals). The tournament typically runs during June and July, coinciding with the South American winter and European summer break, allowing top players from European clubs to participate. Preseason betting markets usually open 6-12 months before the tournament, with initial odds appearing as early as the previous summer following the conclusion of World Cup qualifying campaigns and major international tournaments.

Off-season futures markets for Copa América center heavily on outright winner odds, with Brazil and Argentina consistently favored due to their depth and star power. Golden Boot markets attract significant action, particularly when players like Lionel Messi or Neymar are confirmed participants. Group stage advancement props offer value, especially for teams like Colombia, Uruguay, and Chile that can benefit from favorable draws. Unlike club competitions, there are no transfer windows affecting Copa América odds, but player availability becomes crucial as European clubs sometimes resist releasing players for the tournament, creating dramatic line movements when star players confirm or withdraw their participation.

Vig patterns in Copa América betting typically start wider during the initial futures release, with sportsbooks building in extra margin due to the long-term uncertainty of international tournaments. Lines tighten significantly once squads are announced (usually 30 days before the tournament) and reach their sharpest during the group stage when sample sizes are limited. The biggest odds movements historically stem from injury announcements during the weeks leading up to the tournament, coaching changes within CONMEBOL nations, and the official draw ceremony which can dramatically shift a team's path to the final. Host nation announcements also create immediate market reactions, as home-field advantage proves substantial in South American soccer culture.

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.
