As the United States moves into the legalized sports betting scene the NFL is not expecting a big change in their sponsorship program at least for this year or 2020.
In 2018 the Supreme Court removed a law that banned sports betting across at a federal level, and allowed states to define for themselves if they wished to allow gambling or not and under what conditions. For now, some states have legalized sports betting, but the adoption has been slow by consumers who are finding cumbersome conditions the offshore market is free off.
More taxes on winnings, additional conditions to open an account, accounts cannot be used outside of the state, or in some cases the only way to bet is inside specific licensed casinos.
