Averages are unweighted across all 22 sports each book prices. Books that post lines on many low-liquidity international leagues (e.g. BetMGM, Pinnacle) carry higher averages than their NFL/NBA pricing alone would suggest — compare per-sport rows for like-for-like.
Bally Bet is a fully regulated U.S. sportsbook backed by Bally's Corporation, a long-established name in the casino and hospitality industry. The brand entered the online sports betting space as part of Bally's aggressive expansion into digital gaming, leveraging its brick-and-mortar casino footprint and its ownership of the Bally Sports regional sports networks. Despite the corporate muscle behind it, Bally Bet has been slow to gain traction in a market dominated by DraftKings, FanDuel, and BetMGM. Its availability remains limited to a handful of states, which significantly restricts its competitive reach and user base.
Where Bally Bet falls short is in the areas that matter most to experienced bettors: odds competitiveness, market depth, and promotional offerings. The platform tends to lag behind larger competitors in line quality, and its selection of props, live betting options, and alternate lines is noticeably thinner. The user interface, while functional, lacks the polish and responsiveness of more established apps. On the positive side, Bally Bet benefits from integration with Bally's loyalty program, which can offer value to bettors who also frequent Bally's casino properties. The sportsbook has also shown a willingness to improve its product over time, rolling out incremental updates to its app and expanding its market coverage.
Bally Bet is best suited for casual bettors who already have a connection to the Bally's ecosystem — whether through casino visits, loyalty rewards, or regional sports network fandom. It is not the ideal platform for sharp bettors seeking the best available lines or for high-volume players who need deep liquidity and fast payouts. For those shopping odds across multiple books, Bally Bet can occasionally surface a competitive number, but it is unlikely to serve as anyone's primary sportsbook in its current form. Its long-term viability will depend on whether Bally's Corporation commits the resources needed to close the gap with market leaders.

Bally Bet Odds by Sport
Frequently Asked Questions
How good are Bally Bet odds?
Bally Bet has an average vig of 6.09%, earning a grade of C. They rank #7 out of 20 tracked sportsbooks.
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.
