California AG Bonta joins 37-state coalition defending gambling laws against Kalshi
California Attorney General Rob Bonta has joined a bipartisan coalition of 37 attorneys general in defending state gambling laws against Kalshi, the regulated prediction market platform. Donald Trump Jr. sits on the board of both Kalshi and Polymarket, a detail highlighted in the coverage. The coalition is pushing back against Kalshi's efforts to offer sports-related event contracts that the states argue violate their gambling statutes.
A 37-state coalition significantly raises the legal and political stakes for Kalshi's sports-contract expansion; an adverse outcome could force state-by-state geoblocking and create a template for other states to challenge prediction market products.
Brings the running tally of state attorneys general actions against Kalshi to at least five — California, Ohio, New Mexico, Rhode Island, and Minnesota — as Bonta's 37-state coalition amplifies the legal challenge beyond individual state-court fights into a coordinated interstate front.
