Vig by Bet Type
| Bet Type | DraftKings | FanDuel | BetMGM |
|---|---|---|---|
| Spreads | 4.3% | 4.4% | 4.8% |
| Totals | 4.4% | 4.3% | 4.9% |
| Moneylines | 4.0% | 3.9% | 4.5% |

DraftKings has a meaningful advantage on player props — roughly 0.5% less vig than FanDuel and 1.7% less than BetMGM. Given the popularity of props, this matters.
Same-game parlays and futures are where all three books make significant margin. The vig on futures can exceed 20% at every major sportsbook.
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.
Odds Boosts: Frequency, Terms, and Value
All three books offer daily odds boosts, but the volume, structure, and actual value differ significantly.
| Factor | DraftKings | FanDuel | BetMGM |
|---|---|---|---|
| Daily Boosts | 8–15 | 5–10 | 10–20+ |
| Profit Boost Tokens | Yes (separate) | Occasional | Yes |
| Typical Enhancement | 15–40% | 20–50% | 10–35% |
| Max Bet on Boosts | $10–$50 | $10–$50 | $25–$50 |
| Most Boosted Sports | NFL, NBA, MLB | NFL, NBA | NFL, NBA, parlays |
| Parlay-Specific Boosts | Stepped-up parlays | SGP boosts | Parlay+ boosts |
How many boosts per day?
BetMGM runs the most aggressive boost calendar — on a full NFL Sunday or busy NBA slate, you can see 20 or more individual boosted markets. DraftKings typically posts 8 to 15 standard odds boosts plus separate profit boost tokens that let you apply a percentage increase to a bet of your choice. FanDuel runs fewer daily boosts (5 to 10) but tends to offer larger individual enhancements and sometimes adds flash boosts during primetime games.
The volume fluctuates with the sports calendar. During NFL season all three books run significantly more boosts than in the MLB-only summer months.
Odds boosts vs. profit boosts
DraftKings makes the clearest distinction. An odds boost is a pre-set enhanced price on a specific market — say, boosting the Eagles moneyline from -150 to +100. A profit boost is a token you apply to any qualifying bet, increasing your winnings by a percentage (typically 20–50%) up to a capped payout. FanDuel and BetMGM blend these formats but lean toward pre-set boosts.
Profit boost tokens are generally more valuable because you choose the bet. You can apply them to markets where you have a genuine edge rather than whatever the book decides to promote.
Are boosts actually plus-EV?
Not always. Books design boosts to look generous while still building in margin on many of them. The way to check: calculate the true implied probability of the boosted outcome using sharp lines from Pinnacle or Circa, then compare to the boosted price. If the boosted odds imply a lower probability than the sharp market suggests, the boost is positive expected value.
In practice, roughly 20 to 30 percent of daily boosts across the big three are genuinely plus-EV. The rest look better than standard odds but still carry house edge after the enhancement. BetMGM’s higher boost volume means more total plus-EV opportunities per day, which can partially offset its higher baseline vig.
Boosts and rollover
Unlike offshore sportsbook bonuses, odds boosts at regulated books come with no rollover requirements. You bet the boost, collect any winnings, and withdraw immediately. This makes boosts structurally different from deposit-match bonuses — there is no clearing cost, no time limit, and no minimum handle before withdrawal. For bettors who find rollover math frustrating, regulated book boosts are the closest thing to free value in sports betting.
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.
