DraftKings consistently ranks among the more competitive books for NCAAB odds, particularly on marquee matchups during conference play and the NCAA Tournament. Their spreads and totals on high-profile games often carry lower juice than industry standard, and they're typically quick to post lines for a full slate of games, including mid-major and lower-tier conference matchups that some books are slower to cover. The same-game parlay builder and alternate line options add flexibility for bettors looking to customize their exposure on college basketball.
The main edge DraftKings offers NCAAB bettors is market depth — player props, team totals, and first-half lines are widely available even for games outside the Power Five. However, sharp bettors may find that limits tighten quickly on less-popular markets, and odds can move aggressively after early action. Recreational bettors and those focused on tournament futures or prop variety will get the most value from DraftKings's NCAAB offerings.

How does DraftKings vig compare to offshore books?

In which states is DraftKings available?

Does DraftKings limit winning bettors?
Yes, DraftKings is known to limit or restrict accounts of consistently profitable bettors. This is standard practice among regulated US sportsbooks. Bettors who are limited on DraftKings often turn to offshore sharp-friendly alternatives.
Why is college basketball vig so variable?
NCAAB has hundreds of teams and thousands of games per season. Major conference matchups attract decent volume and competitive vig, but mid-major and early-season games see far less action. Sportsbooks compensate with wider margins on lower-profile games.
When is NCAAB season?
College basketball runs from November through early April, culminating in March Madness (the NCAA Tournament). The tournament generates massive betting interest and typically features some of the best vig of the NCAAB season.
Does March Madness have better vig than regular season?
Generally yes. March Madness is one of the most heavily bet events in American sports. The flood of casual and sharp money forces books to tighten their lines. Tournament vig is often 1–2% lower than early-season college basketball.
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.
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.
