Week 1 of the NFL season gets a lid put on it with this matchup, and it's the first time fans have gotten a chance to see the great Patrick Mahomes in action. However, that return could be spoiled in what is sure to be a tough-fought battle against last season's #1 defense. Denver has won each of the last three meetings, including four of the last five, so Mahomes & Co. will certainly have their work cut out for them tonight.
Kalshi runs as a CFTC-regulated prediction market rather than a sportsbook. You buy Yes or No contracts priced between 1 cent and 99 cents, and each contract settles at $1 or $0 when the event resolves.

Kalshi Promo Code Eligibility and State Availability
Kalshi accepts traders 18 and older, which is a lower age bar than the 21-and-up standard at most sportsbooks. Federal CFTC oversight means the exchange reaches far more of the map than legal online sportsbooks do, including California, Texas, and Georgia.
Sports event contracts are currently unavailable in Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, Ohio, and Washington while litigation plays out. Check kalshi.com/regulatory for the live list before you claim the offer.
Kalshi NFL Odds: Broncos vs Chiefs Preview & Prediction
Let's see how the Kalshi NFL odds stack up for this Broncos vs. Chiefs matchup on Monday Night Football:
| Market | Broncos | Chiefs |
|---|---|---|
| Kalshi moneyline | 45¢ | 56¢ |
| Implied win probability | 45% | 55% |
Kalshi odds are subject to change before kickoff at 8:15 p.m. ET on Monday, September 14, 2026.
Denver enters as the defending AFC West champion, the AFC's No. 1 seed, and the team that lost 14-3 to New England in the conference title game. Kansas City stumbled to 6-11 and missed the playoffs for the first time since 2014 after Patrick Mahomes tore his ACL and LCL in December. Both quarterbacks return Monday, but only one faces immediate structural trouble.
Mahomes took zero preseason snaps, and starting left tackle Josh Simmons sits out with a back injury. That leaves undrafted rookie Khalil Benson on the blind side against a Denver front that racked up a franchise-record 68 sacks last season and became the first team ever to clear 60 in consecutive years. Chris Jones and Chamarri Conner also clouded the Kansas City report, while Denver submitted no injury designations at all.
Bo Nix returns from the ankle fracture he suffered against Buffalo in January, and new coordinator Davis Webb inherits an upgraded pass game now that Jaylen Waddle joins Courtland Sutton, Marvin Mims Jr., and Evan Engram.
Denver swept this series a year ago, including a win at Arrowhead, and covered every time the market made them an underdog. Nik Bonitto and Zach Allen attacking a makeshift line flips games, and Pat Surtain II erases a receiver behind them. Kansas City leans on Kenneth Walker III to shield a quarterback nine months removed from knee surgery, which points toward a grinding, low-scoring night that rewards the healthier roster.
