Caesars Sportsbook, backed by the enormous resources of Caesars Entertainment, is one of the most prominent operators in the regulated U.S. market. Its acquisition of William Hill in 2021 gave it a strong foundation in oddsmaking and risk management, and it has since rebranded and expanded aggressively across dozens of states. As a fully licensed, regulated operator, bettors can expect reliable payouts, legal protections, and responsible account handling — though the book is firmly oriented toward the recreational side of the spectrum and is not particularly accommodating to sharp or high-volume bettors.
Where Caesars stands out most is in its promotional offerings and its integration with the broader Caesars Rewards loyalty program. Bettors who frequent Caesars properties — hotels, casinos, restaurants — can earn and redeem rewards across the ecosystem, which is a genuine differentiator no other sportsbook can match. The app itself has improved significantly since its early post-rebrand days, though it still trails competitors like DraftKings and FanDuel in terms of interface speed, bet slip functionality, and live betting depth. Odds competitiveness is generally middle-of-the-pack; Caesars rarely leads the market on pricing, particularly for NFL and NBA sides, but it occasionally posts favorable lines on player props and secondary markets that are worth monitoring.
Caesars is best suited for casual to moderate bettors who value the loyalty rewards angle and who already engage with the Caesars brand in other ways. It's a solid book to have in a multi-account setup for line shopping purposes, but it's unlikely to serve as a primary platform for serious bettors seeking consistently sharp odds or high limits. Its reliability and regulatory standing are unquestioned, making it a trustworthy option — just not always the sharpest one on the board.

Frequently Asked Questions
What is Caesars's average vig?
Caesars has an overall average vig of 5.23%, earning a grade of C+. They cover 11 sports.
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 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.
