Kalshi runs a US federally regulated exchange that lets traders speculate on whether future events will occur using event contracts. These contracts are approved by the CFTC and enable positions on outcomes like statistics or legislative results. Traders place bets on events via Kalshi’s trading platform, and the company earns revenue from transaction fees on each trade. Kalshi differentiates itself by being the first federally regulated market for event contracts, focusing on a new asset class within the futures ecosystem, and attracting both individual investors and institutional traders. Its goal is to give participants a regulated venue to hedge or speculate on economically significant events, expanding the scope of traditional futures markets.

Tribal casinos' $44B industry faces threat from unregulated prediction market platforms

At the Indian Gaming Association's annual convention this week, tribal leaders focused heavily on the threat posed by prediction markets like Polymarket and Kalshi. Chairman David Bean accused these platforms of circumventing gambling regulations, calling them "unlawful gambling dressed up as finance". Tribal gambling generates over $40 billion annually, funding healthcare, housing and education in Native American communities. Four tribal nations have sued Kalshi and Robinhood, claiming they violate federal law and state-tribal compacts. The platforms argue they operate financial markets, not gambling operations. The association announced a defence fund to support legal actions and called on Congress to regulate prediction markets. However, the Trump administration has backed the platforms, which are already facing lawsuits from more than a dozen states.
