FanDuel and Bally Bet represent two very different tiers of the US sportsbook landscape. FanDuel is a market leader with deep liquidity, aggressive pricing on major markets, and a massive customer base that allows it to operate on thinner margins in high-visibility spots like NFL sides and totals. Bally Bet, backed by Bally's Corporation and its casino portfolio, entered the market as a smaller challenger with more limited state availability and a less refined pricing engine. FanDuel's vig tends to be sharper on mainstream markets due to scale and competition, while Bally Bet's hold can run higher, particularly on secondary markets and props where less competitive pressure exists.
A bettor might prefer Bally Bet in specific scenarios — particularly if they're tied into the Bally's casino ecosystem and value cross-platform loyalty rewards, or if they find themselves limited at larger books. Smaller sportsbooks sometimes offer more tolerance for winning players, at least in their early growth phases. FanDuel, on the other hand, is the stronger choice for most recreational and serious bettors alike. Its odds are consistently competitive across a broad range of sports, same-game parlays are well-constructed, and its promos — while not a reason to choose a book on their own — tend to carry genuine value compared to industry norms.
Beyond vig, the gap between these two books is significant in terms of user experience. FanDuel's app is fast, intuitive, and among the most reliable in the industry, with quick bet settlement and responsive cash-out features. Bally Bet's platform has improved since launch but still lags behind in interface polish, market depth, and payout speed. Bettors should also weigh state availability — FanDuel operates in far more jurisdictions — and consider whether the breadth of betting markets matters to their strategy. For most users comparing these two side by side, FanDuel will win on price and experience the majority of the time.
Vig Comparison by Sport
Frequently Asked Questions
Is Bally Bet or FanDuel better for odds?
Bally Bet currently offers lower vig overall. Bally Bet averages 6.43% vig (C) while FanDuel averages 7.03% vig (D).
How does Bally Bet compare to FanDuel by sport?
We compare both books across 71 sports. The comparison covers vig percentages, grades, and which book offers better odds per sport.
How does FanDuel vig compare to DraftKings?
FanDuel and DraftKings typically have similar vig levels as regulated US sportsbooks. FanDuel occasionally edges ahead on specific markets. Both tend to have higher base vig than offshore books, but offer promotions and same-game parlays to attract recreational bettors.
What makes FanDuel different from offshore sportsbooks?
FanDuel is a regulated, licensed sportsbook operating under state gaming commissions. This means deposit/withdrawal protection, tax reporting, and legal recourse if disputes arise. The tradeoff is generally higher vig and more aggressive bettor limiting compared to offshore alternatives.
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.
