The U.S. Securities and Exchange Commission will soon seek public input on how the agency should treat novel exchange-traded funds, including those based on event contracts.

Chairman Paul Atkins said in a Wednesday statement that the SEC is evaluating 'novel questions' raised by new types of ETFs that have emerged recently, including event contract ETFs.

"I appreciate the willingness fund sponsors have shown in delaying the effectiveness of a number of novel ETFs, including event contract ETFs" Atkins said. "To ensure we do this in a transparent and thoughtful manner, I have instructed the staff to seek input from the public on how the Commission should respond to recent market changes."

Atkins' latest statement confirms that the agency has delayed making a decision on the first wave of prediction market ETFs tied to political and economic outcomes.

According to earlier reports, the delay affected 24 ETFs from issuers including Bitwise, Roundhill, and GraniteShares that were initially set to go live earlier in May. Filings for the funds were submitted in February and were nearing the end of a 75-day review window.
