Robinhood sues Missouri over sports event contracts
Robinhood says federal law pre-empts Missouri’s attempt to regulate its sports event contracts as gambling.
The hit
Robinhood has sued Missouri’s attorney general & the state’s gaming commission, seeking a court order to stop them regulating its sports event contracts. The company filed the complaint in federal court in Missouri on 9 November, according to the filing. Robinhood says the contracts trade on federally regulated exchanges & Missouri has no jurisdiction over them.
Why it matters
The case turns on who gets to decide where Americans can trade sports contracts: state gaming regulators or the federal derivatives watchdog. Robinhood leans on a recent Third Circuit ruling that upheld a finding that Kalshi was likely to succeed in its fight against New Jersey, arguing the same pre-emption principle applies to Missouri.
