Esports is breaking yet another major barrier in the Las Vegas valley. Not only are fans able to watch major events in the new Esports Arena, but they can now bet on video games.

Since 2015, at least a dozen NBA teams, owners and players have invested heavily in the growing e-sports market, backing or buying competitive gaming teams around the globe. Dallas Mavericks owner Mark Cuban, a dot-com pioneer who built a fortune in the tech world, opted for a different route. Instead of buying an e-sports team of his own, Cuban made a bet on betting, investing in a company called Unikrn that sets lines and takes wagers from around the world on e-sports competitions.
