The top 2 books are tightly clustered — only 0.02% separates them. The spread between #1 and #20 is 3.48% — book choice matters significantly for WNBA.
WNBA betting occupies a distinctive niche that rewards sharp bettors willing to do the work. 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 significant weight. Scoring tends to sit in the 75–85 point range per team, with a slower pace and more half-court offense compared to the NBA. This lower-scoring environment means point spreads are tighter — typically in the single digits — and totals hover around 155–170, making every possession matter more for over/under bettors. Market depth is narrower than major men's leagues, with fewer prop and live betting options, though this has expanded steadily as the league's profile has grown.
Vigorish on WNBA lines tends to run wider than what bettors encounter in NFL or NBA markets. Because WNBA attracts lower handle volume, sportsbooks have less incentive to sharpen their lines aggressively, and the reduced liquidity means odds can vary meaningfully from book to book. This is precisely where comparing vig across sportsbooks pays off — the spread between the sharpest and softest lines on a given WNBA game can be notably larger than in higher-volume sports. Early in the season, when books are still calibrating rosters and rotations, lines tend to be softest and margins widest. As the season progresses and betting models mature, vig generally tightens, with playoff games attracting enough action to produce the most competitive odds of the year.
Several factors drive meaningful line movement in WNBA. Roster size is just 12 players, so a single injury — particularly to a franchise player like A'ja Wilson or Breanna Stewart — can shift a spread by three or more points. Home-court advantage is real but inconsistent; some franchises like the Seattle Storm and Las Vegas Aces have historically strong home records, while others show minimal splits. Travel schedules and back-to-back games create fatigue spots that books sometimes underweight. Bettors who track lineup confirmations closely, especially in a league where national media coverage lags behind tip-off, can find edges before lines adjust.

Frequently Asked Questions
Which sportsbook has the lowest vig for WNBA?
Pinnacle currently has the lowest average vig for WNBA at 3.79%, earning a grade of B+.
How do sportsbook odds compare for WNBA?

When do small vig differences matter for WNBA?
The top two books (Pinnacle and LowVig.ag) are separated by just 0.02%. While small, this adds up over volume — a bettor placing $1,000/week saves roughly $0 per week by choosing the lower-vig book.
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.
