(Reuters) - The San Francisco 49ers are slight favourites to defeat the Kansas City Chiefs in Sunday's Super Bowl, according to bookkeepers, with a record 67.8 million Americans expected to place bets on the NFL's title game.
The 49ers, who made a second-half comeback against the Detroit Lions in the NFC Championship, have clinched five Super Bowls but none since their 1994 title.
The Chiefs, who eliminated Baltimore Ravens in the AFC Championship game, are looking to become the first back-to-back Super Bowl champions since the New England Patriots in 2003-04.
Patrick Mahomes' team will be hoping to win their third title in five years while San Francisco will seek revenge for their 31-20 loss in the final game of the season four years ago.
This year's Super Bowl will be played in Las Vegas, marking the first time the event is being held in the U.S. betting capital of Nevada.

This year's Super Bowl is anticipated to set new records in sports betting, with an estimated 68 million Americans expected to wager around $23 billion on the game. Legalized sports betting in 38 states, along with enticing bonuses from online sportsbooks, has contributed to this surge in popularity.
The upcoming Super Bowl features two popular teams in a rematch from the previous year and will take place in Las Vegas, adding to the hype. Additionally, the potential participation of Taylor Swift, due to her relationship with Kansas City Chiefs' player Travis Kelce, is expected to attract more viewers.
Some international betting sites are offering specific bets related to Taylor Swift and her potential involvement in the game, such as whether Kelce will propose to her and whether she will be mentioned by the game's MVP.
