When the Chiefs and Buccaneers exceeded the over/under and the home team in Tampa was stomped by Kansas City, the financial shockwaves were felt by sportsbooks across the United States.
"Toughest NFL week for the sportsbook so far," said Jason Scott, BetMGM VP of trading, of the just-wrapped NFL Week 4. "Chiefs beating the Bucs was the worst result on Sunday. Cardinals, Raiders and Cowboys were also bad outcomes for BetMGM."
Kansas City was +110 on the money line to win outright at kickoff at most books but offered at +140 earlier in the week.
It was the first week of the NFL or college football regular season that BetRivers and PlaySugarHouse lost money, senior manager Troy Machir said.
