According to Wu Blockchain, Bloomberg ETF analyst Eric Balchunas stated that the U.S. SEC has sought public comments on a new type of ETF. This move is partly due to the recent surge in prediction market ETF applications. The SEC aims to establish a unified framework to clarify which products are suitable for ETF issuance, streamline the approval process, reduce backlogs, and prevent issuers from gaining a regulatory advantage by submitting applications early.
