On April 29, Bloomberg ETF analyst James Seyffart stated that the first batch of predictive market exchange-traded funds could be launched in the United States as early as next week. New York-based issuer Roundhill has submitted an effective post-amendment under Rule 485(b) to the SEC, setting the effective date for its six predictive market funds as May 5. These ETFs include a Republican/Democratic presidential ETF targeting the 2028 presidential election, as well as Senate and House ETFs targeting the November 2026 midterm elections.

Seyffart expects that products from GraniteShares and Bitwise, which previously submitted similar applications, will also be launched around the same time. The analyst commented that this move marks the ongoing trend of "financialization and ETF-ization of everything." Earlier in March, the total trading volume of the two major predictive market platforms, Polymarket and Kalshi, reached a record $24.3 billion.
