Serie B, Italy's second division, presents a distinctive betting landscape shaped by its competitive unpredictability and relatively lower market visibility compared to Serie A. The league features 20 teams playing a 38-match regular season, followed by promotion playoffs and relegation playouts, creating high-stakes matches throughout the calendar. Scoring tends to be modest — many matches finish 1-0 or 0-0 — reflecting the tactically conservative DNA of Italian football, where defensive organization often takes priority. This lower-scoring tendency makes the under 2.5 goals market particularly active, while the frequency of draws (often exceeding 28-30% of results) creates value opportunities on the X column that casual bettors frequently overlook.
Vig on Serie B markets tends to run wider than what bettors find on Serie A or top-five European leagues. Because betting volume is lower and bookmakers have less confidence in their pricing models for second-tier Italian football, margins on match result (1X2) markets commonly sit between 5-8%, compared to 3-5% on Serie A fixtures. Moneyline and Asian handicap markets can be even less efficient, particularly for midweek rounds or matches involving lower-profile clubs. This makes shopping across multiple sportsbooks especially critical — the spread between the sharpest and softest books on a given Serie B match can represent meaningful edge over time.
The Serie B season runs from mid-August through mid-May, with the playoff and playout rounds extending into early June. Odds tend to be most competitive during the opening weeks, when bookmakers and the public are still calibrating team strength after summer transfer windows that often reshape rosters dramatically through loans from Serie A clubs. The stretch run from March onward, when promotion races and relegation battles crystallize, also draws increased betting volume and can tighten margins slightly. Key factors affecting odds include squad depth (many clubs rely heavily on loan players whose parent clubs can recall them in January), significant home/away performance splits — particularly at atmospheric grounds like those in Palermo, Bari, or Sampdoria — and fixture congestion during midweek rounds, where rotation patterns become a critical variable for informed bettors to monitor.

Frequently Asked Questions
Which sportsbook has the lowest Serie B - Italy vig?
Pinnacle currently has the lowest vig at 2.81%, earning a grade of A.
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.
