The launch of a prediction market ETF has been postponed as the U.S. Securities and Exchange Commission (SEC) seeks additional scrutiny of its disclosure content, according to Bloomberg ETF analyst Eric Balchunas. The delay is not a rejection but rather a move by regulators to conduct more thorough checks on what is considered a "groundbreaking" product. Following updates to the filing by Roundhill, the ETF's launch may be rescheduled to May 18.
