20/50 states don't allow mobile gambling, so Texas is only one of those 40%. Some of those 20 states (9 to be exact) do allow sports betting, but only physically, not online.

That said, this means very little when a different type of gambling ("prediction markets") is somehow allowed everywhere because of the corruption of the current administration, with the son of the president being a "senior advisor" to both Kalshi and Polymarket, completely circumventing state-wide bans.
