Overall Vig
D · Rank #16 of 20
BetMGM is one of the largest regulated sportsbooks in the United States, born from a partnership between MGM Resorts International and Entain Holdings. That casino industry pedigree gives it a level of brand recognition and infrastructure that few competitors can match. It holds licenses across more than 20 states and has established itself as a consistent top-three operator alongside DraftKings and FanDuel. As a fully regulated book, bettors can expect standard consumer protections, reliable payouts, and compliance with state gaming laws.
BetMGM's strengths lean heavily toward its market breadth and promotional generosity. The platform regularly offers competitive odds on major sports — particularly the NFL, NBA, and major golf tournaments — and its same-game parlay builder is one of the more polished in the industry. The loyalty integration with MGM's M Life Rewards program is a genuine differentiator for bettors who also frequent MGM properties. Where BetMGM falls short is in its treatment of sharp or high-volume bettors. Accounts that consistently beat closing lines can expect to be limited relatively quickly, and the book's odds on niche markets or less popular leagues sometimes lag behind what DraftKings or FanDuel post. The mobile app, while improved over recent years, has historically drawn criticism for occasional sluggishness and a less intuitive interface compared to its main rivals.
BetMGM is best suited for recreational and moderate-volume bettors who value a wide selection of sports, frequent promotional offers, and the added benefit of casino and rewards integration. Sharps looking for high limits and tolerant account management will likely find better options elsewhere, but for the casual-to-serious bettor operating within the regulated U.S. market, BetMGM remains a reliable and competitive choice worth comparing lines against.

Frequently Asked Questions
How good are BetMGM odds?
BetMGM has an average vig of 7.20%, earning a grade of D. They rank #16 out of 20 tracked sportsbooks.

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.
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.
