###Input: The league announced on October 16, 2012, that the two finalists were Sun Life Stadium and Levi's Stadium. The South Florida/Miami area has previously hosted the event 10 times (tied for most with New Orleans), with the most recent one being Super Bowl XLIV in 2010. The San Francisco Bay Area last hosted in 1985 (Super Bowl XIX), held at Stanford Stadium in Stanford, California, won by the home team 49ers. The Miami bid depended on whether the stadium underwent renovations. However, on May 3, 2013, the Florida legislature refused to approve the funding plan to pay for the renovations, dealing a significant blow to Miami's chances.

On May 21, 2013, NFL owners at their spring meetings in Boston voted and awarded the game to Levi's Stadium. The $1.2 billion stadium opened in 2014. It is the first Super Bowl held in the San Francisco Bay Area since Super Bowl XIX in 1985, and the first in California since Super Bowl XXXVII took place in San Diego in 2003.

For the third straight season, the number one seeds from both conferences met in the Super Bowl. The Carolina Panthers became one of only ten teams to have completed a regular season with only one loss, and one of only six teams to have acquired a 15–1 record, while the Denver Broncos became one of four teams to have made eight appearances in the Super Bowl. The Broncos made their second Super Bowl appearance in three years, having reached Super Bowl XLVIII, while the Panthers made their second Super Bowl appearance in franchise history, their other appearance being Super Bowl XXXVIII. Coincidentally, both teams were coached by John Fox in their last Super Bowl appearance prior to Super Bowl 50.

Despite waiving longtime running back DeAngelo Williams and losing top wide receiver Kelvin Benjamin to a torn ACL in the preseason, the Carolina Panthers had their best regular season in franchise history, becoming the seventh team to win at least 15 regular season games since the league expanded to a 16-game schedule in 1978. Carolina started the season 14–0, not only setting franchise records for the best start and the longest single-season winning streak, but also posting the best start to a season by an NFC team in NFL history, breaking the 13–0 record previously shared with the 2009 New Orleans Saints and the 2011 Green Bay Packers. With their NFC-best 15–1 regular season record, the Panthers clinched home-field advantage throughout the NFC playoffs for the first time in franchise history. Ten players were selected to the Pro Bowl (the most in franchise history) along with eight All-Pro selections.

The Panthers offense, which led the NFL in scoring (500 points), was loaded with talent, boasting six Pro Bowl selections. Pro Bowl quarterback Cam Newton had one of his best seasons, throwing for 3,837 yards and rushing for 636, while recording a career-high and league-leading 45 total touchdowns (35 passing, 10 rushing), a career-low 10 interceptions, and a career-best quarterback rating of 99.4. Newton's leading receivers were tight end Greg Olsen, who caught a career-high 77 passes for 1,104 yards and seven touchdowns, and wide receiver Ted Ginn, Jr., who caught 44 passes for 739 yards and 10 touchdowns; Ginn also rushed for 60 yards and returned 27 punts for 277 yards. Other key receivers included veteran Jerricho Cotchery (39 receptions for 485 yards), rookie Devin Funchess (31 receptions for 473 yards and five touchdowns), and second-year receiver Corey Brown (31 receptions for 447 yards). The Panthers backfield featured Pro Bowl running back Jonathan Stewart, who led the team with 989 rushing yards and six touchdowns in 13 games, along with Pro Bowl fullback Mike Tolbert, who rushed for 256 yards and caught 18 passes for another 154 yards. Carolina's offensive line also featured two Pro Bowl selections: center Ryan Kalil and guard Trai Turner.
