When the Super Bowl odds were originally posted when the dust settled on Championship Sunday, the 49ers were a 2.5-point favorite over the defending-champion Kansas City Chiefs.
Bettors were quick to back the Chiefs and quarterback Patrick Mahomes as an underdog (10-1-2 ATS, 9-3 straight up), but the pendulum is starting to swing back toward the NFC Champions.
On Wednesday, a bettor placed a $110,000 wager on the 49ers at -1 at Super Book Sports, according to Ben Fawkes. San Francisco moved to -1.5 after the bet and are back to two-point favorites as of Wednesday morning.
