Brazil's Série B is a 20-team second division running from April through November, featuring a grueling 38-match schedule that creates a constant stream of betting opportunities. The league is characterized by tight, low-scoring matches — typical scorelines hover around 1-1 or 1-0, with home sides historically enjoying a pronounced advantage thanks to the travel demands of a continental-sized country and often hostile local atmospheres. For bettors, this creates an interesting dynamic: draw percentages tend to run higher than in many European second divisions, and the three-way moneyline market rewards those who can identify when a stalemate is the most probable outcome. Market depth is moderate — major international sportsbooks cover match results, over/under totals, and Asian handicaps, but proposition and player-level markets are considerably thinner than what bettors find in top-flight European leagues.
Vig on Série B matches tends to run wider than on Brazil's Série A or major European competitions, reflecting lower liquidity and the informational asymmetry that comes with a league where squad turnover is high and reliable performance data can be harder to source. Three-way moneyline margins commonly sit in the 6–9% range at less competitive books, though sharp operators and exchanges can compress that considerably. This is precisely why comparing margins across sportsbooks matters — the gap between the best and worst price on a given Série B fixture can represent meaningful edge over the course of a full season.
Seasonal timing matters for finding value. Early-round matches in April and May often carry the widest margins as bookmakers price in greater uncertainty around newly promoted clubs, managerial changes, and preseason form. As the season progresses and the picture clarifies — particularly around the promotion and relegation battles that intensify from August onward — odds tighten and become more efficient. Home-and-away splits deserve close attention: clubs playing at altitude or in Brazil's humid northern regions can see amplified home advantages, while fatigue and fixture congestion during midweek rounds late in the season frequently impact squad rotation decisions that slower-moving books are late to price in.

Frequently Asked Questions
Which sportsbook has the lowest Brazil Série B vig?
Pinnacle currently has the lowest vig at 4.58%, 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.
