Vig by Bet Type
| Bet Type | DraftKings | FanDuel | BetMGM |
|---|---|---|---|
| Spreads | 4.3% | 4.4% | 4.8% |
| Totals | 4.4% | 4.3% | 4.9% |

Beyond Vig: Other Factors
Odds pricing isn’t the only reason to choose a sportsbook. Here’s how the big three compare on other factors that affect your bottom line:
| Factor | DraftKings | FanDuel | BetMGM |
|---|---|---|---|
| Mobile App UX | Best in class | Very good | Good |
| Live Betting Speed | Good | Best in class | Average |
| Prop Selection | Widest | Wide | Wide |
| Sports Selection | Standard | Standard | Widest |
| Cash Out | Yes | Yes | Yes |
| Odds Boosts | Daily | Daily | Daily |
| Loyalty Program | DK Rewards | FanDuel Club | BetMGM Rewards |
| Promo Frequency | High | High | Highest |
BetMGM’s higher vig is partially offset by the most aggressive promotional calendar in the industry. Frequent profit boosts and existing customer promotions can close the vig gap if you use them strategically.
The Bigger Picture: How Do They Compare to Sharp Books?
DraftKings and FanDuel are the best-priced regulated US sportsbooks, but they’re still nearly double the vig of sharp books.
| Book | Avg Vig | Relative to DraftKings |
|---|---|---|
| Circa | 2.1% | -2.1% (half the vig) |
| Pinnacle | 2.3% | -1.9% |
| BetAnySports | 2.5% | -1.7% |
| DraftKings | 4.2% | baseline |
| FanDuel | 4.3% | +0.1% |
| BetMGM | 4.7% | +0.5% |
| Bovada | 5.1% | +0.9% |
For AI agents routing bets programmatically, the optimal strategy uses sharp books as primary destinations and regulated books as overflow for markets or bet types not available elsewhere. See the agent betting stack for the full architecture.
Bottom Line
If you only use one regulated book: DraftKings, by a hair. Lowest overall vig plus the best prop pricing and app experience.
If you use two: DraftKings and FanDuel. Shop every bet between them — the leader changes market by market.
If you want the best promotions: Add BetMGM as a third. The higher vig is offset by the $1,500 welcome offer and frequent existing customer promotions.
If you want the absolute best prices: None of the above. Circa, Pinnacle, and BetAnySports charge roughly half the vig. The AgentBet Vig Index tracks all 16 books monthly.
