A moneyline bet in the Copa del Rey is the most straightforward wager available: pick the team that will win the match outright within the designated match period. Unlike league play, the Copa del Rey's knockout format introduces three-way moneyline markets in single-leg ties — win, lose, or draw at the end of regulation — while two-leg series may offer aggregate outcome markets. This distinction matters because a draw is a very live outcome, especially in tightly contested early-round matches, and overlooking it is a common mistake that inflates the effective edge the sportsbook holds.

The moneyline market tends to offer the most value during the earlier rounds when top-flight clubs face lower-division opponents. Bookmakers can struggle to price Segunda B or Tercera División sides accurately due to limited data, creating opportunities for bettors who track squad rotation and lineup news. Heavy favorites like Real Madrid or Barcelona often rest key players in early rounds, narrowing the effective gap. In terms of vig, Copa del Rey moneylines — particularly three-way markets — typically carry slightly higher margins than two-way totals or Asian handicaps, since the additional draw outcome gives books more room to build in juice across three prices rather than two.

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 the Copa del Rey?

The Copa del Rey is Spain's primary domestic football knockout cup competition, organized by the Royal Spanish Football Federation. It features clubs from all divisions of Spanish football, with La Liga giants like Real Madrid and Barcelona entering in later rounds. The final is one of the biggest events in Spanish football.

How does Copa del Rey vig compare to La Liga?

Copa del Rey vig varies by round and matchup. Early rounds with lower-league teams have higher vig due to limited betting volume. Later rounds featuring La Liga clubs have competitive vig, often comparable to regular league matches. The final typically has some of the tightest margins of any Spanish football match.

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.
