Every year, the proposition bets are the main focus of Super Bowl betting, with dozens of articles addressing them appearing in various media and hundreds of props available to bet.
The prop on the time it takes to sing the National Anthem is now a staple of every Super Bowl, and whether you actually have a bet on it or not, it's fun to use your phone to time it.
Here's the history on this bet, listing the respective performers since 2008, the line, and the result:
2016 Lady Gaga: 2:20 - Over
2015 Idina Menzel: 2:01 - Over
2014 Renee Fleming: 2:20 - Under
2013 Alicia Keys: 2:05 - Over
2012 Kelly Clarkson: 1:34 - Over
2011 Christina Aguilera: 1:54 - Over
2010 Carrie Underwood: 1:42 - Over
2009 Jennifer Hudson: 2:04 - Over
2008 Jordin Sparks: 1:47 – Over
Two popular prop bets are "who will score the first touchdown" and "who will be the MVP."
Up until the 2017 game between the Atlanta Falcons and New England Patriots, there had never been an overtime in a Super Bowl, and "no overtime" was always a big favorite, usually going off around -800 or even as much as -1000 (bet $100 to win $10). A lot of sports bettors lost big when the game went into overtime for Super Bowl 51.
While the Nevada books don't put up the wild bets found at the offshore books, they've gotten creative with "cross-sport" props, which match a Super Bowl result with another sport. In 2016, cross-sport bets involved basketball, baseball, soccer, rugby, golf, hockey, and the UFC.
Of course, the sizzle props, including the Anthem bet, are at the offshore books. Here are some of the wilder ones in the recent past.
• Will Beyonce's belly button be visible during her halftime performance?
• Will Peyton Manning announce his retirement in the live post-game interview?
• How many times will "dab" or "dabbing" be said by announcers during the broadcast?
• Will the Panthers player who scores the first TD give the ball to a boy or a girl?
• How many wings will Buffalo Wild Wings sell on Super Bowl day? (The over/under was 12 million.)
• What color will the liquid be that's poured on the winning coach?
It's all part of what makes the Super Bowl the biggest single-day betting event in the world.
