LowVig.ag leads with 3.78% vig (B+), followed by BetOnline.ag at 4.39%. The spread between #1 and #20 is 3.41% — book choice matters significantly for WNBA.
WNBA betting offers a distinct landscape compared to its NBA counterpart. The league's 40-game regular season, running from May through September with playoffs extending into October, creates a compact schedule where each game carries outsized significance. Scoring totals typically land in the 150-170 combined point range, with a slower pace and more half-court-oriented offense than the men's game. Market depth has grown significantly in recent years as the league's popularity has surged, but WNBA lines still attract far less handle than major men's sports — which directly impacts how sharp the odds are and how much value can be found by informed bettors.
Vig on WNBA lines tends to run wider than what bettors encounter in NFL or NBA markets. While a competitive NBA spread might sit at -108/-108 or -110/-110 across top sportsbooks, WNBA lines frequently carry heavier juice, sometimes reaching -115 on both sides of a spread. This reflects the lower betting volume and the reduced incentive for books to sharpen their numbers aggressively. However, that dynamic also means there's more line disparity between sportsbooks, making odds comparison particularly valuable. Bettors who shop lines across multiple books can capture meaningful edges that simply don't exist in higher-volume markets.
Several factors make WNBA odds uniquely volatile. Roster sizes are small — just 12 players — so a single injury to a star like A'ja Wilson or Breanna Stewart can move a line by 5 or more points. There are no weather considerations since all games are played indoors, but travel and scheduling deserve attention; back-to-back games and cross-country trips create fatigue spots that books don't always fully account for. Home-court advantage is meaningful but inconsistent across the league, with certain venues like Seattle's Climate Pledge Arena historically producing stronger home splits. Early in the season, when rosters are still gelling and books have less data to work with, odds tend to be softer and present the best opportunities for bettors doing their own research.

Frequently Asked Questions
Which sportsbook has the lowest vig for WNBA?
LowVig.ag currently has the lowest average vig for WNBA at 3.78%, earning a grade of B+.
How do sportsbook odds compare for WNBA?
We compare 20 sportsbooks for WNBA. The vig ranges from 3.78% (LowVig.ag) to 7.19% (888sport).
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.
