It turns out Warren Buffett may be as good at predicting football outcomes as he is at reading the markets.

The CEO of Berkshire Hathaway, who is reportedly worth upwards of $65 billion, laid down his first-ever wager at a Las Vegas sports book over the weekend. Buffett bet $550 at the MGM Grand on his alma mater, the Nebraska Cornhuskers. Because the Cornhuskers easily covered the 12.5-point spread in a 55-19 blowout of Fresno State, Buffett earned $500.

According to CNBC, a few other bettors saw Buffett lay down the cash on Nebraska and rushed over to make the same wager. Smart people.

Buffett was in Las Vegas for Floyd Mayweather's rematch with Marcos Maidana. The 84-year-old billionaire and the undefeated prizefighter have become buddies of late.

Buffett has boosted his sports profile considerably over the past year. Before the 2014 NCAA tournament, Buffett announced a $1 billion bracket challenge for anyone who could predict every single result of the men's basketball tournament. Not only did it earn Buffett tons of publicity, he got to keep his money. It only took 25 games for everyone who entered the challenge to be eliminated.
