Polymarket has filed applications seeking U.S. regulatory approval to offer margin trading to customers. The proposal would allow users to take positions that are not fully collateralized, subject to regulated terms. Reporting indicates that the move follows existing U.S. authorization granted to Kalshi, a rival prediction market platform, which received approval to provide margin trading in March. The filings are positioned as an effort to bring Polymarket’s product closer to U.S. regulatory standards for trading and customer protections. While details of the final regulatory outcome are not yet known, both outlets note that Polymarket’s request comes in the wake of Kalshi’s approval, suggesting regulators are already considering margin features for prediction market platforms. The application does not confirm whether approval will be granted, what conditions may be imposed, or when margin trading would become available to U.S. users.
