BetMGM is one of the largest regulated sportsbooks in the United States, born from the partnership between MGM Resorts International and Entain (formerly GVC Holdings). Licensed and operational in more than 20 states, it benefits from the brand recognition and infrastructure of one of the most established casino companies in the country. That pedigree gives it a level of trust and reliability that newer or lesser-known operators struggle to match — deposits, withdrawals, and account management generally function smoothly, backed by dedicated customer support and the broader MGM Rewards ecosystem.
In terms of strengths, BetMGM offers a deep menu of betting markets across major American sports, with competitive odds on mainstream NFL, NBA, and MLB lines. Its same-game parlay builder is well-designed, and the platform regularly features boosted odds promotions that can carry genuine value when scrutinized against the true implied probabilities. However, BetMGM's odds on less popular markets — particularly niche props, lower-tier leagues, and some live betting lines — tend to carry higher juice compared to sharper books like Circa or Pinnacle. Bettors who consistently win may also find their accounts limited or restricted over time, a common practice among recreational-facing sportsbooks but one that places BetMGM firmly outside the "sharp-friendly" category.
BetMGM is best suited for casual to moderate bettors who value a polished user experience, access to MGM's loyalty rewards program, and a wide selection of promotional offers. It's an excellent option for recreational players who bet primarily on major sports and appreciate the convenience of tying their sportsbook activity to in-person casino perks. High-volume or professional bettors, however, will likely find better long-term value and fewer account restrictions elsewhere.

Frequently Asked Questions
What is BetMGM's average vig?
BetMGM has an overall average vig of 6.45%, earning a grade of C. They cover 17 sports.
How does BetMGM vig rank among regulated books?

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.
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.
