Proponents and opponents of daily fantasy sports (DFS) in Nebraska have locked horns as the state opens the debate on the industry’s regulation.

Omaha World Herald reported that DFS giants DraftKings and FanDuel both pointed out at the start of the debate on Legislative Bill 469 that there’s a need to regulate fantasy sports in order to protect their customers. They said that 300,000 of the 57 million fantasy sports players in the US are from Nebraska.

On the issue on whether DFS is a game of skill or a game of chance, both operators argued that their games require skill to draft players, research opponents and set fantasy lineups.

“This is not an expansion of gambling,” Sean Ostrow, who is a representative of Fan Duel, told the Senate, according to the news report.
