Frequently Asked Questions

Is BetMGM or BetUS better for odds?

BetUS currently offers lower vig overall. BetMGM averages 7.00% vig (D) while BetUS averages 5.73% vig (C+).

How does BetMGM compare to BetUS by sport?

We compare both books across 72 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.

How does BetUS vig compare to other offshore books?

BetUS generally has higher vig than sharp-focused offshore books like Pinnacle, BetOnline, or LowVig.ag. They invest heavily in marketing and promotional bonuses, which results in wider odds margins. They're better suited for casual bettors who value bonuses.

What are BetUS bonus terms like?

BetUS offers generous-sounding welcome bonuses (often 100%+ match) but with significant rollover requirements — typically 10x or more. This means you may need to bet through the bonus amount 10+ times before withdrawing. Read the terms carefully before opting in.

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.

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.
