Frequently Asked Questions

Is FanDuel or Caesars better for odds?

Caesars currently offers lower vig overall. FanDuel averages 6.70% vig (C) while Caesars averages 6.28% vig (C).

How does FanDuel compare to Caesars by sport?

We compare both books across 75 sports. The comparison covers vig percentages, grades, and which book offers better odds per sport.

How does FanDuel vig compare to DraftKings?

FanDuel and DraftKings typically have similar vig levels as regulated US sportsbooks. FanDuel occasionally edges ahead on specific markets. Both tend to have higher base vig than offshore books, but offer promotions and same-game parlays to attract recreational bettors.

What makes FanDuel different from offshore sportsbooks?

FanDuel is a regulated, licensed sportsbook operating under state gaming commissions. This means deposit/withdrawal protection, tax reporting, and legal recourse if disputes arise. The tradeoff is generally higher vig and more aggressive bettor limiting compared to offshore alternatives.

Is Caesars Sportsbook the same as William Hill?

Yes — Caesars Entertainment acquired William Hill in 2021 and rebranded US operations as Caesars Sportsbook. Our data may show "Caesars" or "William Hill" depending on how the API reports the book. The odds and vig are the same entity.

How does Caesars vig compare to other regulated books?

Caesars typically has similar vig to DraftKings, FanDuel, and BetMGM. They compete more on loyalty rewards (Caesars Rewards program) and retail sportsbook access than on odds quality. Sharp bettors will find better pricing at offshore books.

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 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.

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.
