The Caribbean Premier League (CPLT20) occupies a distinctive niche in the T20 franchise cricket landscape. Matches are played across multiple Caribbean nations, each with its own pitch characteristics and ground dimensions, creating significant variability in scoring patterns. Small grounds in venues like Providence, Guyana, tend to produce high-scoring affairs, while slower surfaces in Trinidad or Jamaica can reward disciplined bowling. For bettors, this venue-by-venue variation is a critical edge — understanding how individual grounds behave under lights, in humidity, and with dew can separate sharp wagers from uninformed ones. Market depth is narrower than for the IPL or Big Bash, with fewer sportsbooks offering extensive prop and innings-specific lines, which means the markets that do exist can carry exploitable inefficiencies.
Vig on CPLT20 markets tends to run wider than on higher-profile T20 leagues. Because the tournament draws less global betting volume, sportsbooks build in larger margins to protect against liability from sharper action that represents a bigger share of the handle. Match-winner lines often carry margins in the 5–7% range, compared to 3–5% for top-tier cricket competitions. Totals and player prop markets, where available, can be even wider. This makes shopping across multiple books especially valuable — the spread between the best and worst available price on the same outcome can be significant enough to meaningfully impact long-term returns.
The CPL typically runs from late August through early October, a window that overlaps with the Caribbean's rainy season. Weather interruptions are a genuine factor, with Duckworth-Lewis-Stern recalculations altering match dynamics and creating live-betting opportunities for those who understand the method's quirks. Early in the tournament, when rosters are still settling and overseas players are adjusting to conditions, odds tend to be softer and less efficient. As the group stage progresses and form lines become clearer, books sharpen their pricing. Bettors should also monitor franchise-specific roster turnover, as CPL teams rely heavily on a handful of international marquee players whose availability — or sudden departure for national duty — can dramatically shift a team's competitive outlook.

Frequently Asked Questions
Which sportsbook has the lowest CPLT20 vig?
Pinnacle currently has the lowest vig at 7.07%, earning a grade of D.
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 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 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.
