WNBA betting presents a distinct landscape compared to its NBA counterpart. Games are played in four 10-minute quarters with a 30-second shot clock, producing final scores that typically land in the 70–85 point range. The smaller roster sizes — 12 players per team with only five starters — mean that individual player impact is magnified significantly. A single absence can swing a spread by four or more points. Market depth has grown considerably in recent years as sportsbooks have expanded offerings beyond moneylines and spreads to include player props, team totals, and quarter-by-quarter lines, though liquidity still lags behind the major men's leagues.
Vig on WNBA lines tends to run wider than what bettors encounter in NFL or NBA markets. Standard spreads and totals often carry juice in the -112 to -115 range at less competitive books, compared to the -110 standard in higher-volume sports. This is a direct reflection of lower betting volume and the sharper risk sportsbooks face when setting lines for a league with fewer data points and more volatile outcomes. However, the gap between the sharpest and softest books can be substantial, making line shopping particularly valuable. Bettors who consistently find -108 or -110 juice instead of -115 are protecting meaningful margin over a full season.
The WNBA regular season typically runs from May through September, with playoffs extending into October. Early-season lines tend to be softer and carry wider vig as books calibrate rosters following offseason movement, midseason additions from overseas leagues, and the impact of new draft picks. The Commissioner's Cup tournament games in June and July can also create pricing inefficiencies. Home-court advantage is a real but modest factor — roughly 2.5 to 3 points in most models — while rest and travel schedules matter more than in the NBA due to the league's heavy use of commercial flights. Monitoring injury reports closely is essential, as the loss of a franchise player like A'ja Wilson or Breanna Stewart can completely reshape a team's offensive and defensive profile overnight.

Frequently Asked Questions
Which sportsbook has the lowest WNBA vig?
LowVig.ag currently has the lowest vig at 3.77%, earning a grade of B+.
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 every hour, on the hour (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 average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.
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, BetAnything). 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 every hour, on the hour (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.
