BetMGM and Caesars Sportsbook are two of the largest regulated operators in the US market, both backed by legacy casino empires with deep roots in Las Vegas. Despite surface-level similarities, they differ meaningfully in execution. BetMGM, a joint venture between MGM Resorts and Entain, tends to lean into a tech-forward approach with competitive main-market pricing and frequent odds boosts across major sports. Caesars, powered by its acquisition of William Hill's infrastructure, has historically been more aggressive with promotional spending and loyalty integration, tying its sportsbook tightly to the Caesars Rewards ecosystem. In terms of vig philosophy, neither consistently undercuts the other across the board — the live data on this page will show where each book is sharper on a market-by-market basis.
A bettor who values a polished mobile experience and tends to wager on NFL, NBA, and major event props may find BetMGM's interface and market depth slightly more refined. Its parlay-building tools and in-app cash-out options are generally well-regarded. On the other hand, a bettor who frequents Caesars properties or travels to Las Vegas regularly gets outsized value from Caesars Rewards tier credits earned through sports wagering — a tangible benefit that compounds over time. Caesars also tends to offer more aggressive new-user and retention promotions, which can matter for bettors who actively shop bonuses.
Beyond vig, bettors should weigh practical factors like withdrawal speed, bet limits, and how each book handles sharp action. BetMGM has a reputation for being quicker to limit winning accounts, while Caesars — inheriting some of William Hill's tolerance for action — can be marginally more accommodating for consistent winners, though neither is considered truly sharp-friendly. Payout processing times are comparable, but Caesars edges ahead for users with existing casino accounts due to streamlined verification. Checking the real-time vig comparison above remains the most reliable way to determine which book is offering better value on any specific wager.
Vig Comparison by Sport
Frequently Asked Questions
Is BetMGM or Caesars better for odds?
Caesars currently offers lower vig overall. BetMGM averages 7.39% vig (D) while Caesars averages 5.89% vig (C+).
How does BetMGM compare to Caesars by sport?
We compare both books across 71 sports. The comparison covers vig percentages, grades, and which book offers better odds per sport.
How does BetMGM vig rank among regulated books?
BetMGM typically sits in the middle of the pack among regulated US sportsbooks. Their vig is comparable to DraftKings and FanDuel, though it varies by sport and market. They compete primarily on brand recognition and their MGM Rewards loyalty program.
Does BetMGM have good odds for any specific sport?
BetMGM occasionally offers competitive pricing on NBA and NHL markets where they have strong trading desks. However, their overall vig profile is similar to other regulated books. Check our sport-by-sport breakdown above for current rankings.
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.
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 exceptional and rare — these are typically sharp-friendly books. A (2–3%) is excellent. B+ (3–4%) is above average. B (4–5%) is the industry standard for most recreational sportsbooks. C (5–6%) is below average. D (above 6%) indicates high-juice markets where bettors face a steep cost per wager.
- 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.
