Pinnacle leads with 3.93% vig (B+), followed by BetMGM at 4.38%. The spread between #1 and #17 is 3.79% — book choice matters significantly for NFL Preseason.
NFL preseason betting occupies a peculiar niche that rewards research-intensive bettors willing to navigate thin information markets. Unlike the regular season, preseason games feature massive roster turnover within a single contest — starters may play a single series in early August before giving way to second- and third-stringers fighting for roster spots. This creates scoring patterns that bear little resemblance to regular-season football: totals tend to be lower, outcomes are more volatile, and the final score often reflects the depth of a franchise's roster rather than its starting talent. Market depth is limited compared to the regular season, with many books offering only sides, totals, and moneylines, and sharp action can move lines quickly given the smaller handle sizes.
Vig on NFL preseason lines tends to run wider than during the regular season, often settling in the -110/-110 range on sides but frequently creeping to -115 or worse on totals and props. The reasoning is straightforward: books face greater uncertainty in setting accurate lines when coaching staffs deliberately obscure playing-time plans, and they compensate for that liability by building in extra margin. Smaller betting volume also reduces competitive pressure to sharpen prices. Bettors comparing across sportsbooks will often find meaningful vig differences on the same game, making line shopping particularly valuable during this window.
The NFL preseason typically runs from early August through late August, with three games per team. Odds tend to be most competitive for the second preseason game, when books have at least one data point to calibrate lines and volume picks up slightly. The first week often features the widest margins due to pure uncertainty. Key factors driving line movement include coaching staff announcements about starter availability, position battles that shift depth chart projections, and even venue — teams playing at home in early preseason often have slight edges as they control the operational tempo. Bettors should also track which franchises historically prioritize preseason wins versus those that treat August purely as an evaluation period, as this philosophical divide significantly impacts effort level and, ultimately, outcomes.

Frequently Asked Questions
Which sportsbook has the lowest vig for NFL Preseason?
Pinnacle currently has the lowest average vig for NFL Preseason at 3.93%, earning a grade of B+.
How do sportsbook odds compare for NFL Preseason?
We compare 17 sportsbooks for NFL Preseason. The vig ranges from 3.93% (Pinnacle) to 7.72% (ReBet).
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.
