The Commodity Futures Trading Commission (the CFTC or Commission) issued a notice of proposed rulemaking on June 10, 2026, seeking public comment on proposed amendments to CFTC Regulation 40.11.1 The proposed amendments further specify the types of event contracts that may be subject to a public interest determination under Section 5c(c)(5)(C) of the Commodity Exchange Act (CEA), i.e., the "Special Rule" that authorizes the CFTC to prohibit the trading or clearing of certain event contracts on or through CFTC-registered entities.2
