Kansas City entered the Week 7 Super Bowl rematch as 2.5-point road underdogs (-110) at BetMGM Sportsbook. If that sounds familiar, it's because the Chiefs were 2.5-point 'dogs against the 49ers in Super Bowl LVIII, too. Bettors certainly believed in Mahomes and the Chiefs: Roughly 72% of money (straight-up bets and parlays) were laid on Chiefs moneyline at +115 odds, per BetMGM’s John Ewing. Despite an underwhelming statistical day from Mahomes (16-for-27, 154 yards, two interceptions), the Chiefs defeated San Francisco on the road, 28-18, to win their highly-anticipated matchup. With Mahomes under center, the Chiefs are now 5-0 SU against the 49ers, including 2-0 in Super Bowl meetings. Mahomes and the Chiefs are also 2-0 SU/ATS as an underdog against the Niners. Mahomes in particular has been historically successful as an underdog. According to Action Network’s Evan Abrams, Mahomes owns the best mark in the Super Bowl era as an underdog, boasting a 11-3 SU record and 12-1-1 ATS mark.
Patrick Mahomes moves to 11-3 straight up and 12-1-1 against the spread as an underdog — best mark in the Super Bowl era.

For some perspective, the rest of the NFL wins about 32% of games SU as an underdog since 2000. pic.twitter.com/yeUeV4mjyp
The Chiefs are off to the best start for a reigning champion since the Patriots opened 8-0 in 2019. Kansas City and the 1990 49ers are the only back-to-back Super Bowl champions to start 5-0. The Chiefs are the NFL’s last unbeaten team and remain the favorites to win Super Bowl 59, with +475 odds at BetMGM.
