Bloomberg ETF expert analyst James Seyffart announced via X that the first prediction market-based ETF is expected to launch next week. U.S. investment firm Roundhill's launch date is set for May 5 (local time), with bets placed on whether the Republican or Democratic party will control the House and Senate in the upcoming midterm elections. Similar ETFs from Bitwise and GraniteShares are also expected to launch around the same time. Bitwise had applied for a prediction market-based ETF in February.
