FanDuel is one of the two dominant sportsbooks in the regulated U.S. market, consistently competing with DraftKings for the top market share position in nearly every state where it operates. Originally built on the back of its daily fantasy sports platform, FanDuel transitioned into full-scale sports betting after the fall of PASPA in 2018 and has since become the go-to book for millions of American bettors. It operates legally across dozens of states, backed by parent company Flutter Entertainment, one of the largest gambling corporations in the world. That corporate infrastructure translates into a reliable, well-funded product with consistent payouts and strong regulatory oversight.
FanDuel's primary strengths lie in its user experience and promotions. The app is widely considered the cleanest and most intuitive in the U.S. market, with fast bet placement, a well-organized same-game parlay builder, and competitive odds on major sports — particularly NFL and NBA. Its promotional engine is aggressive, offering regular boosts and new-user incentives that rival or exceed the rest of the industry. Where FanDuel falls short is in its treatment of winning bettors. Like most U.S.-regulated books, it leans heavily toward the recreational side, and sharp bettors may find their accounts limited or their lines adjusted after sustained success. Its odds on less popular markets — such as lower-tier soccer leagues or niche props — also tend to carry wider margins compared to books with more international reach.
FanDuel is best suited for casual to moderate bettors who value a polished experience, fast deposits and withdrawals, and a steady stream of promotions. It's an excellent choice for someone betting primarily on mainstream American sports and who wants the security of a fully regulated operator. High-volume professionals or bettors seeking the sharpest possible lines may find better value elsewhere, but for the majority of U.S. bettors, FanDuel remains a top-tier option.

Frequently Asked Questions
What is FanDuel's average vig?
FanDuel has an overall average vig of 6.79%, earning a grade of C. They cover 48 sports.
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 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.
