BetMGM is one of the largest regulated sportsbooks in the United States, born from a partnership between MGM Resorts International and Entain. Licensed and operating across more than 20 states, it carries the weight of a legacy casino brand and the infrastructure of a major international betting operator. That combination gives it a level of credibility and regulatory standing that few competitors can match. It consistently ranks among the top three or four US sportsbooks by market share, alongside DraftKings, FanDuel, and Caesars.
BetMGM's strengths lie in its broad market coverage, competitive odds across major sports, and a well-integrated rewards program tied to the MGM ecosystem — a genuine differentiator for bettors who frequent MGM properties. Its same-game parlay builder is solid, and it regularly offers boosted odds promotions that can carry real value when analyzed carefully. Where BetMGM falls short relative to competitors is in its app experience, which has historically lagged behind the smoother interfaces of DraftKings and FanDuel. Line availability for niche markets and lower-tier leagues can also be thinner, and sharp bettors may find their accounts limited more aggressively than at some competing books. Odds on secondary markets don't always keep pace with the sharpest lines available elsewhere.
BetMGM is best suited for recreational to moderate-volume bettors who value a trusted, regulated platform and want access to strong promotions without needing the deepest possible market depth. Bettors already embedded in the MGM loyalty ecosystem stand to gain the most. For high-volume sharps or those focused on obscure prop markets, it functions better as one book among several rather than a primary outlet.

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 every hour, on the hour (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.
What sportsbooks do you track?
We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnything). 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 every hour, on the hour (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.
