The first prediction market ETFs may reach the U.S. market as soon as next week. Bloomberg senior ETF analyst James Seyffart said a new filing from Roundhill Investments lists an effective date of May 5, putting the launch window for these products in focus.
Roundhill filed six ETFs linked to U.S. election outcomes
Roundhill Investments, a New York-based fund issuer, filed the products on February 14. The lineup includes six ETFs tied to political prediction markets and built around future U.S. election results.
The RPM Democratic President ETF and RPM Republican President ETF are linked to the 2028 U.S. presidential election. Four others — RPM Democratic Senate ETF, RPM Republican Senate ETF, RPM Democratic House ETF, and RPM Republican House ETF — track which party controls Congress after the November 2026 midterm elections.
Seyffart points to a May 5 effective date
After reviewing the latest filing, Seyffart said it looks like prediction market ETFs are set to launch next week. If that timeline holds, investors would be able to take positions on political outcomes through standard ETF wrappers rather than through standalone prediction platforms.
He described the move as part of a broader shift toward the financialization and ETF-ization of almost everything. In this case, contracts tied to real-world political events are being packaged into exchange-traded funds that can be accessed through regular brokerage accounts.
Bitwise and GraniteShares may enter the market at the same time
Roundhill is not the only issuer in the field. The report says GraniteShares and crypto ETF issuer Bitwise also filed similar products in February. Seyffart expects issuers to launch around the same period, so the week of May 5 could bring several prediction market ETFs to market together.
Prediction markets already handle billions in trading volume
Prediction markets have expanded quickly in recent years, especially around major political events. Platforms such as Polymarket and Kalshi gained traction by letting users trade contracts based on real-world outcomes. According to the report, the two U.S. platforms posted a combined $24.3 billion in trading volume in March 2026 alone.
If these ETFs launch as indicated in the filing, the same type of event-based exposure would move into a familiar ETF structure for investors using standard brokerage channels.
