Unfortunately America lags behind most of the world when it comes to Betting and online gambling in general. A few states do allow online gambling on some level. New Jersey has been pushing for sports betting for a while now with no success. I did recently read that the Supreme Court has agreed to hear the case sometime this year but I don't know much about the case or how eSports betting would be effected by it.
