Line dancing: Big money behind Chiefs shifts SB LVIII odds

Heavy early money backing the Kansas City Chiefs led to multiple changes in the betting line within 24 hours of the matchup for Super Bowl LVIII being set.

The San Francisco 49ers opened as 2.0-point favorites shortly after storming from behind to beat the Detroit Lions in the NFC Championship Game on Sunday night. However, the line dipped as low as 1.0 points at sportsbooks including DraftKings and BetMGM, where the Chiefs had been backed by 78 percent of the spread-line money as of Monday morning.

The line has since shifted back to San Francisco being favored by 1.5 points at both sportsbooks, who both have the Over/Under points total at 47.5 points. The early money at BetMGM has the Over being backed by 90 percent of the money wagered on the market.

Sportsbooks were widely pulling for the Lions to upset the 49ers, who are the biggest Super Bowl liability at many sportsbooks, and that remains the case ahead of facing the Chiefs.

"Even though early action is on the Chiefs as underdogs, the sportsbook is cheering for a Kansas City victory," BetMGM senior trading manager Tristan David said.

Chiefs quarterback Patrick Mahomes is the early favorite to claim his third Super Bowl MVP award. The MVP of Super Bowls LIV and LVII, Mahomes is +120 to claim No. 3 at BetMGM, where he opened the season at +1000. 49ers quarterback Brock Purdy is second at +220, followed by teammate Christian McCaffrey at +450.

Mahomes has drawn 20 percent of the MVP money at DraftKings, where he is also +120. Teammate Travis Kelce has far longer odds at +1200, but the tight end has been the second most popular early pick with 14 percent of the money backing him.

The most popular player prop at DraftKings has been McCaffrey at -155 to lead all players in combined rushing and receiving yards. He has also been the most popular Anytime Touchdown play despite -215 odds.
