Louisiana AG sues Kalshi, Polymarket, Robinhood, Coinbase, and Gemini over prediction markets

Louisiana's attorney general has sued Kalshi, Polymarket, Robinhood, Coinbase and Gemini over their prediction market offerings. The action sharpens the conflict between state and federal oversight of event contracts, a product line several crypto-linked platforms are expanding into. Traders should watch for state-level restrictions that could curb prediction market revenue and add legal risk for Coinbase and peers.
