MS HB172

Revises the definition of "sports pool" to explicitly include single-game bets, teasers, parlays, over-under, moneyline, pools, exchange wagering, in-game wagering, in-play bets, proposition bets, and straight bets.

Defines "platform" as a person or entity operating a sports pool or race book over the internet (websites and mobile devices) on behalf of a gaming license holder, with authority to accept/reject wagers, determine results, and process payouts.

Authorizes platforms to be licensed as distributors under gaming regulations and exempts wagers placed through approved platforms from the requirement that bettors be physically present at the licensed establishment.

Establishes a lower gaming license fee of 6% on gross revenues received through platforms (versus 8% on other gross revenues exceeding $134,000 per month).

Deletes the prohibition on fantasy contest operators offering contests based on collegiate sports event performance, while maintaining prohibitions on high school and youth sports contests.
