Betting on professional and college sports from a cellphone or other electronic device, an issue debated by North Carolina lawmakers for more than two years, could clear a major hurdle Tuesday.

The state House is expected to vote on legalization Tuesday afternoon. A similar bill failed by a single vote in the House last year. Supporters, however, are confident they have enough backing now.

More than two dozen states have legalized mobile sports gambling since a 2018 U.S. Supreme Court decisions gave states the authority. Proponents, which include the state’s professional sports teams and some venues, point to a loss of revenue from gamblers who use out-of-state or off-shore accounts.

The latest version of the bill, modified before the House rules committee Tuesday morning, does not include parimutuel wagering on horse or dog races, moves the start date to Jan. 8 and increases the amount of money for athletic departments at the 10 UNC System schools that do not compete at the Football Bowl Subdivision level.

Those schools would receive 20% of tax revenue, up from 10%, after required distributions. The state’s general fund would receive 50%, down from 60%.

The bill has more than 50 sponsors in the 120-member House. If passed, the bill must clear the Senate, which voted for similar legislation last session, and be signed by Gov. Roy Cooper, who has indicated his support and included revenue from sports gambling in his latest two-year budget proposal.
