Kalshi secures exclusive US Open partnership amid legal battles
Kalshi has secured an exclusive prediction market partnership with the U.S. Tennis Association (USTA) for the US Open. The agreement, which took effect following the tournament's qualifying rounds, reportedly prevents competing prediction market platforms from advertising at the venue or during ESPN television broadcasts.
This commercial expansion occurs alongside significant legal challenges regarding the regulatory status of prediction markets. A federal appeals court in the Ninth Circuit recently ruled that Nevada can apply its state gambling laws to Kalshi’s sports event contracts, rejecting the company's argument that such contracts are financial swaps regulated exclusively by the Commodity Futures Trading Commission (CFTC).
The ruling creates a circuit split, as the Third Circuit had previously ruled in favor of Kalshi, finding that federal law preempted New Jersey's ability to regulate its contracts. This legal conflict between federal oversight and state gambling authority increases the likelihood of the issue being reviewed by the U.S. Supreme Court.
