It took 27 unanswered points to start the second half for the San Francisco 49ers to advance to the Super Bowl, setting up a rematch from Super Bowl 54 against the Kansas City Chiefs. 

Kansas City – the defending Super Bowl champions – has gone on an amazing playoff run, upsetting both the Buffalo Bills and Baltimore Ravens as road underdogs to reach Super Bowl 58. 

San Francisco trailed 24-7 at the half against Detroit in the NFC Championship, but the team took advantage of some costly Lions turnovers – and Dan Campbell’s fourth-down decision-making – to take a 10-point lead late in the fourth quarter. 

Brock Purdy and company have now orchestrated back-to-back comeback wins in the playoffs, but they certainly would like to avoid that scenario in Super Bowl 58.

The 49ers came into the NFC title game as the favorite to win the Super Bowl, and that hasn’t changed in the opening odds for their matchup with the Chiefs. 

Let’s break down the opening odds for Super Bowl 58, including how likely Vegas thinks it is that the 49ers will hoist the Lombardi Trophy in two weeks.

49ers odds to win Super Bowl 58

At -135 odds, Vegas is giving the San Francisco 49ers a 57.45 percent chance of winning the Super Bowl, based on implied probability. 

This shouldn’t come as a surprise to bettors and 49ers fans, as the team has been favored to win the Super Bowl since the start of the playoffs – and for most of the regular season. 

San Francisco’s shaky showings in the first half of both playoff wins can be a concern, but the team has shown it can win when it matters. 

If bettors want to wager on the spread, they can also get the 49ers to cover inside a field goal. San Fran is 0-2 against the spread so far this postseason. The team struggled mainly as a home favorite in the 2023 season, going 3-7 ATS. 

This is a neutral site game, so it will be hard to take certain trends into account. Still, Vegas believes that it is more likely the 49ers hoist the Lombardi Trophy than the Chiefs.
