Overview

• League officials said contracts on platforms such as Kalshi, Robinhood and Polymarket raise the same integrity risks as sportsbooks, including susceptibility to manipulation.
• Executives cited missing safeguards like mandatory information sharing with leagues, formal integrity monitoring and restrictions on influenceable prop-style markets.
• Kalshi recently expanded football event contracts to outcomes resembling prop bets, including touchdown counts, point spreads and total scores.
• The regulatory fight is intensifying as Robinhood sues Nevada and New Jersey to keep offering sports contracts, while tribes including the Ho-Chunk Nation and three California nations pursue cases over activity on sovereign lands.
• Courts have split on state authority, with Nevada and New Jersey temporarily blocked from halting offerings during litigation and a Maryland ruling allowing enforcement stayed pending appeal, as competitors eye the space through moves like Polymarket’s QCEX deal and FanDuel’s CME partnership without sports initially.
