Eagles emerge as 1.5-point favorites over Chiefs in Super Bowl LVII

Oddsmakers initially made Super Bowl LVII a toss-up, but the Philadelphia Eagles emerged as the betting favorites over the Kansas City Chiefs on Sunday.

Caesars Sportsbook and other bookmakers opened the line on Super Bowl LVII at pick 'em Sunday night. Within 30 minutes of posting the line, the Eagles became 1.5-point favorites.

For now, the line is one of the smallest point spreads in Super Bowl history. Only four previous Super Bowls have had point spreads of less than 2. No Super Bowl has ever kicked off with a consensus closing line of pick 'em, although some sportsbooks had Super Bowl XLIX between the New England Patriots and Seattle Seahawks as a pick 'em.

The favored team in the Super Bowl is 39-17 straight up, according to ESPN Stats & Information's archived point spreads.

Philadelphia advanced to the franchise's fourth Super Bowl with a 31-7 win over the San Francisco 49ers on Sunday in the NFC Championship Game. The Eagles overcame long odds to get there. Philadelphia was as long as 50-1 to win the Super Bowl in the offseason at Caesars Sportsbook, which had 15 teams listed ahead of the Eagles. Their odds improved after a draft-day trade for receiver A.J. Brown, but they still kicked off the season as midtier contenders at 25-1 to win the Super Bowl.

The Chiefs, on the other hand, were among the top favorites all season. They began the season at 11-1 to win the Super Bowl at Caesars Sportsbook, but after a blowout win over the Arizona Cardinals in Week 1, they had single-digit Super Bowl odds the rest of the way.

Kansas City knocked off the Cincinnati Bengals in a dramatic AFC Championship Game to advance to the Super Bowl for the second time in four seasons behind quarterback Patrick Mahomes, the favorite to win the regular-season MVP award.

The Chiefs have been favored in their past 15 playoff games, the longest such streak of the Super Bowl era.

An all-time high of $179.8 million was bet on last year's Super Bowl at Nevada sportsbooks, the most of any state that reported betting figures on the Super Bowl. Nevada sportsbooks won a net $15.4 million on last year's Super Bowl. The state's sportsbooks have suffered a net loss on the Super Bowl only twice since Nevada Gaming Control began tracking the action on the NFL championship in 1991.

The over/under total on the Super Bowl opened at 49.5.
