BetMGM and MyBookie.ag represent two fundamentally different approaches to sports betting. BetMGM operates as a fully regulated U.S. sportsbook, licensed state by state and backed by the MGM Resorts empire — one of the largest gaming corporations in the world. Its vig tends to be competitive on major markets, particularly NFL and NBA sides, where it aggressively prices lines to attract volume. MyBookie.ag, by contrast, is an offshore operator based in Curaçao, serving U.S. bettors outside the regulated framework. Offshore books like MyBookie often offer a wider menu of props, more generous early lines on niche markets, and fewer restrictions on account types — but they operate without the consumer protections that come with state-level licensing.
A bettor might prefer BetMGM when reliability and payout security are paramount. Deposits and withdrawals are processed through regulated banking channels, disputes can be escalated to state gaming commissions, and promotional offers — particularly first-bet bonuses and odds boosts — are frequent and genuinely competitive. Sharp bettors, however, may find BetMGM quick to limit accounts that consistently beat closing lines. MyBookie.ag can appeal to bettors who want access to early lines, high-volume parlays, or markets that regulated books don't always carry, such as entertainment or political props. It also accepts action from states where legal sportsbooks haven't yet launched.
Beyond vig, the differences are significant. BetMGM's interface is polished, its app is among the best in the regulated market, and same-game parlay functionality is deeply integrated. MyBookie's platform is functional but dated by comparison. The critical distinction remains payout reliability — BetMGM payouts are guaranteed under law, while offshore withdrawals can involve delays, fees, or cryptocurrency requirements. Bettors comparing odds between these two should weigh not just the number on the screen but what happens after the bet wins.

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 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.
