Bo Nix and the Denver Broncos are set to kick off their AFC West title defense on the road, and the stage couldn't be bigger. The 2026 regular season opener pits the Broncos against Patrick Mahomes and the Kansas City Chiefs on Monday Night Football, and early betting lines suggest it'll be a tight contest.

FanDuel Sportsbook has installed Denver as slight +2.5-point underdogs for the primetime showdown at Arrowhead Stadium. The moneyline sits at +140 for the Broncos, while the over/under is set at 43.5 points, with oddsmakers leaning slightly toward the under at -118. Given the hostile environment and the Chiefs' pedigree, it's no shock that Kansas City enters as favorites—a sentiment reflected in broader AFC West and AFC futures odds.

The Chiefs remain the division favorites at +170, followed closely by the Los Angeles Chargers at +185 and the Broncos at +210. In the AFC championship race, the Baltimore Ravens lead the pack at +490, with the Buffalo Bills (+500), Chargers and Chiefs (+750), New England Patriots (+800), Houston Texans (+950), and Broncos (+1,000) trailing. Oddsmakers still have plenty of faith in Mahomes and company, but early-season uncertainty could shift the landscape.

With kickoff still months away, it'll be fascinating to watch how the line moves. Questions linger around Mahomes' injury status, the Chiefs' offensive line, and their defense. Meanwhile, the Broncos return nearly every starter on both sides of the ball—losing just one player from last year's squad—and have added a dynamic weapon in receiver Jaylen Waddle. That continuity could be a major advantage.

Beyond the odds, Denver has a scheduling win here: getting the Arrowhead trip out of the way in September rather than December, when weather and playoff stakes amplify the challenge. With so many unknowns surrounding Kansas City, this Monday Night Football opener promises to be a thrilling start to the regular season.
