NBA just inked deals with $KALSHI and Polymarket - first major sports league to officially partner with prediction markets.

Key terms:
• Kalshi + Polymarket get official NBA IP rights
• Access to league data via Sportradar for settlement
• Promo deals across U.S. channels
• League personnel BANNED from trading NBA contracts
• Mandatory suspicious activity reporting

This is huge for on-chain prediction markets legitimacy. Traditional sports finally embracing crypto-native infrastructure with compliance guardrails.

Polymarket already doing $100M+ daily volume - this partnership could 10x that for NBA season alone.

Regulated prediction markets = the new frontier for sports betting liquidity.
