Pinnacle leads with 7.99% vig (D), followed by BetMGM at 8.03%.
The Copa del Rey presents a distinctive betting landscape compared to La Liga due to its knockout format and the frequent mismatches in early rounds. When top-tier clubs face lower-division opponents, moneyline markets can feature extreme odds, with favorites sometimes priced at -2000 or steeper. This creates challenges for bettors seeking value, but it also opens opportunities in handicap and totals markets, where the uncertainty around squad rotation and motivation levels can create genuine edges. The two-legged tie format used in certain rounds (though the competition has shifted to single-elimination in recent years) and the possibility of extra time and penalties add layers of complexity that sharp bettors can exploit, particularly in live betting scenarios where in-game dynamics shift rapidly.
Margins on Copa del Rey matches tend to be wider than those found in La Liga, particularly in early-round fixtures involving smaller clubs. Sportsbooks have less data and fewer market participants on these games, which reduces competitive pressure to sharpen lines. As the tournament progresses into the quarterfinals, semifinals, and final, vig typically tightens considerably — these matches draw significant public and sharp attention, forcing books to offer more competitive pricing. Bettors comparing odds across multiple sportsbooks during the later rounds will often find meaningfully better value than those who default to a single book.
The Copa del Rey runs roughly from late October through mid-April, with early rounds featuring the widest margins and the least efficient lines. Key factors influencing odds include squad rotation — managers at top clubs frequently rest star players in early rounds, dramatically affecting expected performance. Home advantage matters more than usual, as lower-division clubs playing on their own smaller, often less pristine pitches can neutralize the technical superiority of elite opponents. Injury news released close to kickoff is especially impactful given the rotation-heavy nature of team selection, making late line movement a reliable signal for informed bettors tracking confirmed lineups.

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 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.
