Miami Dolphins at Las Vegas Raiders: Odds and Betting Preview
The Las Vegas Raiders open as moderate favorites to host the Miami Dolphins on Sunday, September 13, with the moneyline consensus pointing to a roughly 65-68% implied win probability for Las Vegas across major books. The odds tell a straightforward story: the Raiders are expected to win at home, but the Dolphins are live enough that the market is pricing in genuine uncertainty.
What the Moneyline Says
The Raiders moneyline ranges from -185 at Kalshi to -208 at BetRivers and Bovada. That spread matters if you're shopping lines. At -185, the implied probability sits around 64.9%. At -208, it jumps to roughly 67.5%.
For bettors backing Miami, the difference is even more meaningful. Dolphins backers can find +186 at Kalshi versus just +155 at BetMGM and BetRivers. The best available Dolphins line of +186 implies a 35% win probability; the worst of +155 implies roughly 39.2%. That discrepancy reflects real disagreement across the market about exactly how much of an edge Las Vegas holds.

Key Moneyline Numbers to Know
- Best Raiders line: -185 (Kalshi)
- Worst Raiders line: -208 (BetRivers, Bovada)
- Best Dolphins line: +186 (Kalshi)
- Worst Dolphins line: +155 (BetMGM, BetRivers)
If you're on Miami, Kalshi gives you significantly more value than the major retail books. The moneyline gap between the best and worst Dolphins price is over 30 cents, which is substantial.
Spread and Totals for Raiders vs. Dolphins
The spread market is mostly settled at Raiders -3.5, with a couple of outliers worth noting. Bovada, Fanatics, and MyBookie are posting Raiders -4, while Kalshi is an outlier at Raiders -5.5 with steep juice (-179 Raiders, -213 Dolphins). For practical purposes, this market comes down to a choice between -3.5 and -4.
The juice differences on the -3.5 line are worth attention. LowVig.ag and Polymarket are offering Miami +3.5 at +100, while FanDuel is charging Dolphins bettors -104 for the same number. On the Raiders side, -3.5 ranges from -104 at Novig to -118 at FanDuel. That juice variance around a key number like 3 or 4 makes this a market where line shopping is rewarded.
The over/under is tightly clustered around 40.5 across almost every book, with BetRivers sitting slightly lower at 40. Standard price at 40.5 is -110 on both sides at most books, with LowVig.ag offering -108 on each side. A total in the low 40s reflects oddsmakers expecting competent defense or limited offensive firepower from one or both teams. If your read is that this game goes over the number, BetRivers' 40 gives you a full point of cushion compared to the consensus.
Factors That Could Move the Line
Venue. Allegiant Stadium in Las Vegas is a dome, so weather is not a factor. That removes one of the more common line-movement triggers and keeps the focus squarely on the teams.
Injury reports. The NFL injury report will be worth monitoring closely as rosters finalize through training camp and the preseason. Any significant changes at quarterback or skill positions for either side could shift the spread by a point or more.
Line movement. The spread has already split between -3.5 and -4 across books, which can signal that sharper money has acted early. Tracking how the number moves as kickoff approaches adds useful context. The Steam Moves tool is built for exactly that kind of real-time line tracking.
Home field. Las Vegas holds home field advantage, and the market is pricing that in.
Bottom Line
The Raiders are a moderate home favorite, with the market putting their win probability somewhere between 65% and 68% depending on which book you use. The Dolphins are not a long shot, and the best available price of +186 reflects that bettors backing Miami at the right book are getting reasonable value for a team very much in play to win outright.
