Gambling on sporting events and online fantasy sports betting became legal in Arizona on Monday, along with a host of new gambling options at tribal casinos, after the U.S. Department of the Interior approved an updated tribal gaming compact with the state.

Arizona tribes are going to get at least four new casinos – and possibly more – along with more slot machines, more games of chance and the right to take wagers on a whole new category of sporting events.

Gov. Doug Ducey is expected to sign legislation by the end of the week legalizing not just sports gambling but also the ability of folks to create and wager on their own fantasy teams. And there's more:

Sadly, here in Arizona our governor has taken a different approach, ignoring the needs of horse racing and the multitude of rural, locally owned businesses that support the industry. There has been no meeting, no conversation, no discussion about how the state can help us modernize the industry as we can compete with other states.

A top legislative priority for Gov. Doug Ducey to expand off-reservation gaming is stalled in the Senate after the House voted 48-12 to approve a mirror bill on March 4.

Plans by Gov. Doug Ducey to allow statewide sports wagering, betting on fantasy leagues, keno and more tribal gambling could be undermined by a southern Arizona lawmaker.

Details obtained Monday by Capitol Media Services reveal a multi-pronged proposal which would vastly expand what kind of legal wagering can occur here, both on and off-reservation.

Gov. Doug Ducey wants to open the door to allowing Arizonans to bet on -- or against -- the Diamondbacks and the Cardinals. And maybe even the Wildcats and Sun Devils.

A Republican lawmaker has a proposal to legalize sports betting in Arizona through legislation he says will avoid nullifying state gaming compacts with Native American tribes.

Gambling revenues dipped slightly at Arizona’s tribal casinos in 2016, but those losses were more than offset by a strong jump in non-gaming revenues that helped boost total income to $2.23 billion for the year, a new report says.
