A moneyline bet in boxing is the most straightforward wager available: pick which fighter wins the bout. Unlike team sports where point spreads create balanced two-sided markets, boxing moneylines often feature extreme pricing gaps because mismatches are common on major cards. It's not unusual to see a favorite listed at -1500 or higher, which fundamentally changes how bettors should approach the market. The absence of a spread mechanism means the moneyline is the primary betting vehicle in boxing, and books know it — pricing tends to reflect not just probability but also public perception and promotional hype surrounding marquee names.
The moneyline market offers the most value in competitive matchups where the odds fall between -200 and +200, as the vig tends to be more reasonable when books need to attract action on both sides. In lopsided fights, the juice on heavy favorites can balloon dramatically, sometimes pushing combined vig above 10%. Bettors should closely evaluate fighting styles, recent activity levels, weight class changes, and training camp reports, as boxing outcomes hinge on individual preparation far more than team sports. Comparing moneyline vig across books is especially critical in boxing because pricing discrepancies between sportsbooks tend to be wider than in more liquid markets like NFL or NBA.

Frequently Asked Questions
What is a moneyline bet?
A moneyline bet is the simplest form of sports wagering — you're picking which team will win the game outright, with no point spread involved. The odds reflect each team's implied probability of winning. Favorites have negative odds (e.g., -150) and underdogs have positive odds (e.g., +130).
Why does moneyline vig vary by matchup?
Moneyline vig is lowest on evenly matched games and highest on lopsided matchups. When a heavy favorite is -500, the book needs a wide margin on the underdog side to balance risk. Close games near pick'em (-110/-110) will always have the tightest vig.
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 exceptional and rare — these are typically sharp-friendly books. A (2–3%) is excellent. B+ (3–4%) is above average. B (4–5%) is the industry standard for most recreational sportsbooks. C (5–6%) is below average. D (above 6%) indicates high-juice markets where bettors face a steep cost per wager.
- 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.
