↓ 7-day trend: Average vig has improved by 0.13 percentage points over the past week (from 7.06% to 6.93%). Sportsbooks are tightening their lines — a good sign for bettors.
Pinnacle dominates Serie B - Italy with 1.45% less vig than the runner-up BetOnline.ag. The spread between #1 and #13 is 5.61% — book choice matters significantly for Serie B - Italy. Vig is trending down 0.27% since yesterday.
Serie B, Italy's second division, presents a distinctive betting landscape shaped by its competitive parity and tactical unpredictability. Unlike Serie A, where a handful of dominant clubs drive predictable market patterns, Serie B features 20 teams with relatively narrow quality gaps, leading to tighter matches and frequent draws. The league averages around 2.4–2.6 goals per game, slightly lower than Serie A, reflecting the conservative, defense-first approach that many newly relegated or promotion-chasing sides adopt. For bettors, this means the 1X2 market is genuinely three-way in a large share of fixtures, and the under 2.5 goals line hits at a notably high rate. Market depth is thinner than top-flight Italian football — live betting options and prop markets are more limited, and liquidity at most sportsbooks is lower, which directly impacts pricing efficiency.
That reduced liquidity is the key reason vig margins in Serie B tend to run wider than in Serie A or other major European leagues. Books price these matches with less confidence due to smaller data pools, less public betting volume, and fewer sharp bettors actively correcting lines. Moneyline overrounds of 6–8% are common, and some offshore books push margins above 10% on midweek fixtures. This makes shopping across multiple sportsbooks particularly valuable — the spread between the best and worst available price on a given Serie B match can be meaningfully larger than what bettors encounter in top-tier leagues.
The Serie B season runs from mid-August through mid-May, with a brief winter break around the Christmas period. Margins tend to tighten slightly during the playoff phase (May–June), when public interest and betting volume increase around the promotion playoffs. Home advantage is a pronounced factor, historically stronger than in Serie A, partly because many Serie B clubs play in smaller, more intense venues, and travel across Italy's lower-division circuit can be grueling. Bettors should also monitor squad turnover carefully — Serie B rosters are heavily influenced by loan deals from Serie A clubs, which can shift mid-season during the January window, and suspensions accumulate quickly given the league's physical style of play.

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.
