The American Hockey League sits in a unique space for bettors — it's the highest level of minor league hockey in North America, serving as the primary development league for the NHL, yet it receives a fraction of the betting attention. The AHL season typically runs from October through mid-April, with Calder Cup playoffs extending into June. Scoring tends to run higher than the NHL, with games frequently landing in the 3-4 goal range per side, partly because goaltending is less consistent and defensive systems are still being refined. Roster volatility is the defining characteristic: players shuttle between the NHL and AHL on a near-daily basis, and a team's lineup on Tuesday night can look dramatically different from its Saturday roster. This constant churn creates both opportunity and risk for sharp bettors willing to track transactions closely.
Vig on AHL markets tends to run noticeably wider than on NHL games, often sitting in the 6-8% range on moneylines compared to the 3-5% typical of major league hockey. The reason is straightforward — books face thinner betting volume and less public interest, so they build in larger margins to protect against informed bettors who may have better intelligence on roster moves and lineup changes. Not all sportsbooks even offer AHL lines, and among those that do, the variation in juice can be significant, making line shopping particularly valuable in this market.
Several factors disproportionately affect AHL odds compared to major professional leagues. Call-ups and send-downs are the single biggest driver — a team losing its starting goaltender or top scorer to the NHL parent club mid-week can swing a line dramatically. Home-ice advantage tends to be more pronounced than in the NHL, partly due to travel logistics and smaller, louder arenas that amplify crowd effects. Early in the season, when rosters are most unsettled and books have the least data to work with, odds tend to carry wider margins. As the season progresses and playoff races tighten, sharper lines and slightly better vig typically emerge, particularly for teams drawing more consistent betting interest.

Frequently Asked Questions
Which sportsbook has the lowest AHL vig?
theScore Bet (ESPN Bet) currently has the lowest vig at 6.29%, earning a grade of C.
What is the AHL?
The AHL (American Hockey League) is the primary development league for the NHL. It runs from October through June, with all 32 teams affiliated with NHL franchises. AHL vig is typically higher than NHL because betting volume is significantly lower, but sharp books still offer reasonable prices.
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.
