BetMGM and ReBet represent two different tiers within the regulated U.S. sportsbook landscape. BetMGM is one of the largest operators in the country, backed by the MGM Resorts and Entain partnership, with deep roots in casino gaming and a massive existing customer base. Its sportsbook benefits from extensive brand recognition, a well-developed loyalty program tied to MGM's M Life Rewards, and widespread state availability. ReBet, by contrast, operates as a newer, leaner entrant in the regulated market, positioning itself as a sharper alternative that appeals to bettors who prioritize competitive pricing over flashy promotions and brand prestige.
The vig philosophy between the two books can differ meaningfully depending on the market. BetMGM tends to build in slightly higher margins on mainstream lines, offsetting this with frequent promotional offers like profit boosts, deposit bonuses, and same-game parlay incentives. ReBet generally targets more price-conscious bettors by offering tighter spreads on standard markets, making it a better fit for high-volume or flat-stake bettors who understand that small differences in juice compound significantly over time. Casual bettors who value a polished app experience, live streaming options, and promotional perks will likely gravitate toward BetMGM, while more analytical bettors focused purely on line value may find ReBet consistently worth checking first.
Beyond vig, bettors should weigh several practical factors. BetMGM offers a mature, feature-rich platform with reliable payouts, extensive market depth across major and niche sports, and a well-staffed customer support operation. Its limits on recreational accounts are generally generous, though sharp bettors may find themselves restricted over time. ReBet's track record on limit tolerance, payout speed, and market breadth is still developing relative to a legacy operator like BetMGM, so bettors should monitor their own experience on both platforms and let the live odds data on this page guide where to place each specific wager.

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 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.
