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

HB 3156 modifies Missouri's "Show-Me Sports Investment Act" to govern state funding for large athletic and entertainment facilities. It directly affects MLB and NFL teams seeking state support for projects costing at least $500 million with seating over 30,000. Key provisions cap annual state spending at the facility’s baseline year tax revenue (from operations), limit funding to 30 years, and require local government approval for projects over $100 million. The bill also prohibits including residential or retail development in eligible projects and mandates compliance with state infrastructure funding laws.
