Modifies the provisions of the "Show-Me Sports Investment Act"

HB 2883 modifies Missouri's "Show-Me Sports Investment Act" to govern state funding for professional sports facilities. It allows the state to provide financial assistance (up to the facility's baseline tax revenues annually) to MLB or NFL teams for new or upgraded athletic venues with seating over 30,000, requiring projects to cost at least $500 million. The bill restricts funding to exclude tax revenues from the 2026 FIFA World Cup in specific counties and caps state spending at 50% of project costs via bonds over a 30-year period. This directly affects professional sports franchises seeking state support for facility development in Missouri.
