↑ 7-day trend: Average vig has worsened by 0.16 percentage points over the past week (from 7.15% to 7.30%). Odds margins are widening, meaning bettors are getting less value per wager.
Pinnacle leads with 4.75% vig (B), followed by Bovada at 5.21%. The spread between #1 and #12 is 4.35% — book choice matters significantly for Primeira Liga - Portugal.
Portugal's Primeira Liga offers a distinctive betting landscape shaped by a stark competitive hierarchy. The dominance of Benfica, Porto, and Sporting CP creates a market where match odds for the "Big Three" against lower-table sides are heavily skewed, often producing prohibitive moneyline favorites. However, the mid-table and relegation battles are where sharper bettors find value — clubs like Braga, Vitória de Guimarães, and Gil Vicente produce tighter, more unpredictable matchups. Scoring patterns tend to be moderate, with league averages typically hovering around 2.4–2.7 goals per match, making totals markets nuanced rather than straightforward. The league also features notable home advantage, particularly at intimidating venues like Estádio da Luz and Estádio do Dragão, where home win rates for top clubs can exceed 75%.
Vig on Primeira Liga matches varies significantly depending on the sportsbook and the profile of the fixture. Marquee matches involving the Big Three attract higher handle and more competitive lines, often pushing margins below 4% on match result markets at the sharpest books. For lower-profile fixtures — a Friday night match between Famalicão and Estrela da Amadora, for instance — margins can widen to 6% or more, as books price in lower liquidity and reduced market scrutiny. Comparing vig across operators becomes especially important in these less prominent matches, where the spread between the tightest and loosest books can meaningfully erode expected value.
The Primeira Liga season runs from mid-August through late May, with a brief winter break in late December. Early-season fixtures often present softer lines as bookmakers calibrate rosters following the summer transfer window — Portuguese clubs frequently undergo significant squad turnover due to player exports to wealthier leagues. The January transfer window creates another period of pricing uncertainty, particularly for selling clubs that lose key contributors mid-season. Weather is a factor from November through February, especially in northern venues like Braga and Guimarães, where rain-soaked pitches can suppress scoring and favor more physical, defensive sides. Bettors should also monitor UEFA competition schedules closely, as Portuguese clubs competing in Champions League and Europa League frequently rotate squads for domestic fixtures, creating exploitable discrepancies in team news-sensitive markets.

Frequently Asked Questions

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.
