This move by the SuperBook is just the latest of Vegas outs, such as MGM, moving into other jurisdictions, although they could expand more than they have and they face competition from other new sportsbook operators.
The Wire Act, however, remains at least a concern vis-a-vis establishing truly national books accepting wagers across state lines. I don't follow all this closely like David Purdum with ESPN.com and legalsportsreport.com -- other things to do -- but I don't see the demise of offshore in the US soon.
I do wish I could open a new Pinnacle account from within the US at the very least to access their line information, particularly their dropdowns with their specific alternate line pricing.
Mobile definitely is the big thing, though, within the states that have enough sense to allow it; and it was even before the pandemic. And the mobile/in-person breakdown really is not a matter of demographics. This old timer -- both as to age and years betting -- loves mobile where available to me to bet significant amounts; and I'm not the only one. Many younger and/or newer bettors still will be drawn to entertainment-type brick-and-mortar sports bar type books for all the buzz and excitement. And if this last spring break was any indication, many of them are not corona-phobic about being in large gatherings. I just have a hard time believing that, once the government-imposed lockdowns end, young Americans in a 300 million plus person economy are going to stop going out due to the possibility of nationwide losses even in the maybe 100,000 range.
This is LSR's take on the SuperBook development:
