Betting odds accurately predicted the Game of Thrones finale

Quartz

"Vegas currently favors Three-Eyed Raven over Sansa, Daenerys, Jon Snow, Tyrion and Cersei," The Wrap reported on May 9. TMZ warned on May 13 that Bran was such a sure thing that "betting on him won't make you a bunch of cash." As Dan Kopf explains, "the best explanation for the accurate odds on Bran was that the outcome was leaked. Before the season began, a Reddit user was able to describe the ending in almost exact detail.  This another argument against allowing people to gamble on an outcome already known to some people, like the results of a TV show. It is an unusually easy opportunity for insiders to make money at the expense of a less-knowledgable general public."
