Bally Bet is the online sportsbook arm of Bally's Corporation, one of the largest casino operators in the United States. Operating in the regulated US market, it launched with the backing of a well-established brick-and-mortar gaming brand and a significant media partnership through Bally Sports regional networks. Despite that infrastructure advantage, Bally Bet has struggled to carve out meaningful market share against dominant competitors like FanDuel, DraftKings, and BetMGM. Its availability remains limited to a handful of states, which constrains both its user base and the volume of competitive odds it can offer.
Where Bally Bet falls short is in the areas that matter most to experienced bettors: odds competitiveness, market depth, and promotional value. The platform's lines tend to lag behind sharper books, and the variety of betting markets — particularly for props, player-level wagers, and international sports — is noticeably thinner than what larger competitors provide. The user interface is functional but lacks the polish and speed that bettors accustomed to top-tier apps expect. On the positive side, Bally Bet benefits from its integration with Bally's casino properties, offering loyalty rewards and cross-platform perks that appeal to bettors who also frequent their physical locations. The brand's regulatory standing is solid, backed by full state licensing and the credibility of a publicly traded parent company.
Bally Bet is best suited for casual, recreation-oriented bettors — particularly those already loyal to the Bally's casino ecosystem or who watch sports through Bally Sports broadcasts. It is not a go-to option for sharp or high-volume bettors seeking the best available lines. For those comparing odds across multiple books, Bally Bet's lines are worth monitoring but rarely lead the market. Its long-term viability will depend on whether the company invests aggressively enough in its digital product to close the gap with more established sportsbook apps.

Frequently Asked Questions
What is Bally Bet's average vig?
Bally Bet has an overall average vig of 6.28%, earning a grade of C. They cover 16 sports.
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 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.
