According to an ESPN, Sin City’s sports books lost $11.4 million bucks on the series. The gambling world expected the Los Angeles Dodgers to take the Fall Classic, and when the ‘Stros pulled it out, chaos ensued. The $11.4 million bested the previous biggest World Series loss for Vegas sportsbooks. When the New York Yankees unexpectedly took down the Atlanta Braves in the 1999 World Series, the books lost an estimated $6.2 million.
But don’t feel too bad for the Las Vegas books: they finished 2017 at a net gain of $213.6 million. That makes 2017 the fourth most lucrative gambling year ever. The best year, 2015, earned them $231.7 million.
