NFL files Supreme Court brief opposing federal oversight of prediction markets

The National Football League has joined the push against federal oversight of prediction markets including Kalshi and Polymarket, filing an amicus brief with the U.S. Supreme Court as the dispute appears to be moving closer to a final ruling. The filing adds a major sports organization to a case that has drawn attention from multiple political and regulatory figures. According to the report, several other briefs were also submitted to the Supreme Court this week. Those filings included documents from former regulator Gary Gensler and former Senator Chris Dodd. The case centers on who should hold authority over prediction markets at the federal level, an issue with implications for platforms operating in event-based trading. The report also noted that Dodd had previously pushed legislation that the Commodity Futures Trading Commission, or CFTC, cites in arguing that it should have final authority as the regulator for prediction markets.
