Bally Bet and BetRivers represent two different strategies for gaining traction in the competitive US sportsbook market. BetRivers, operated by Rush Street Interactive, has been live since 2018 and has built a reputation as a sharp-friendly, no-nonsense book with competitive pricing across major and secondary markets. Its vig tends to run tighter than the industry average, particularly on NFL sides and totals, making it a staple in the portfolios of serious line shoppers. Bally Bet, backed by Bally's Corporation, entered the market later and with a more modest footprint, leveraging the Bally's casino and media brand to attract casual and crossover bettors. Its odds can be competitive on marquee events but tend to carry slightly wider margins on less popular markets, reflecting a book still scaling its trading operation.
A bettor focused on consistently finding the best number will generally lean toward BetRivers, which routinely posts lines that compete with Pinnacle-influenced offshore pricing. BetRivers also tends to be quicker to market with derivative and prop offerings. Bally Bet, on the other hand, may appeal to bettors who already have a relationship with Bally's properties or who are looking to take advantage of promotional offers aimed at growing the platform's user base. In states where both are available, having accounts at each allows bettors to cross-reference pricing and capture the occasional outlier line from Bally Bet's less mature odds-setting engine.
Beyond vig, the practical differences are notable. BetRivers offers a polished, reliable interface with fast payouts — typically processed within 24 hours for e-wallets — and has a track record of tolerating moderate winning action before adjusting limits. Bally Bet's app experience has improved but still trails BetRivers in terms of market depth, bet slip functionality, and live betting responsiveness. Bettors should also weigh geographic availability: BetRivers operates in significantly more states, while Bally Bet's reach remains limited. For anyone comparing these two books, the live vig data on this page provides the clearest signal of where the value sits on any given event.
Vig Comparison by Sport
Frequently Asked Questions
Is Bally Bet or BetRivers better for odds?
Bally Bet currently offers lower vig overall. Bally Bet averages 6.43% vig (C) while BetRivers averages 7.60% vig (D).
How does Bally Bet compare to BetRivers by sport?
We compare both books across 71 sports. The comparison covers vig percentages, grades, and which book offers better odds per sport.
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.
