No. Sports betting is illegal in Idaho and that's unlikely to change in the near future.
There have been no recent attempts to legalize sports betting and the only types of betting allowed in Idaho are the lottery and horse racing.
While sports betting isn't completely off the table, it doesn't help that the Attorney General issued a press release in 2016 that Daily Fantasy Sports don't abide by the state's gambling laws. And so, Idaho is one of the few states that does not have fantasy sports. That being the case, it's hard to see sports betting becoming legal before the state's stance on fantasy sports changes.
