The top 2 books are tightly clustered — only 0.05% separates them. The spread between #1 and #20 is 3.47% — 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 tends to be lower and possessions more half-court oriented, which means point spreads are tighter — typically ranging from 1 to 12 points rather than the 15-plus-point spreads occasionally seen in the NBA. This compression makes spread betting more volatile and totals markets particularly interesting, as a single cold shooting stretch can swing an over/under result. Market depth has improved significantly in recent years with the league's rising popularity, but WNBA lines still don't attract the same volume of sharp action as major men's leagues, which has direct implications for how books price their markets.
Vigorish on WNBA lines tends to run wider than what bettors encounter in NFL or NBA markets. Because handle sizes are smaller and books have less incentive to sharpen their numbers through competitive pricing, margins of 5-7% on sides and totals are common, with some books pushing even higher on player props and alternative lines. This makes shopping across multiple sportsbooks especially valuable — the difference between a -110 and -115 line adds up quickly over a full season. Odds tend to be most competitive during the playoffs and in nationally televised games, when betting volume increases and books tighten their margins to attract action. Early-season lines, by contrast, often carry the widest vig as books calibrate their models to roster changes, new draft picks, and evolving team dynamics.
Several factors weigh heavily on WNBA odds that bettors should monitor closely. Roster depth is shallower than in the NBA, so a single injury to a franchise player — think a team losing its primary scorer or facilitator — can shift a spread by 4 or more points. Home-court advantage is meaningful but inconsistent; some franchises draw energetic crowds that genuinely affect outcomes, while others play in near-empty arenas. Travel schedules matter as well, as teams frequently fly commercial and play road-heavy stretches that create fatigue-driven edges. Additionally, the mid-season Olympic break in qualifying years disrupts rhythm and can produce unpredictable results in the games immediately following the hiatus, creating opportunities for bettors paying attention to context that the broader market may overlook.

Frequently Asked Questions
Which sportsbook has the lowest vig for WNBA?
LowVig.ag currently has the lowest average vig for WNBA at 3.80%, earning a grade of B+.
How do sportsbook odds compare for WNBA?

When do small vig differences matter for WNBA?
The top two books (LowVig.ag and Pinnacle) are separated by just 0.05%. While small, this adds up over volume — a bettor placing $1,000/week saves roughly $1 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.
