Roundhill Investments is poised to introduce the first US exchange-traded funds linked to prediction markets, with the launch of six funds that will track the likelihood of Democrats or Republicans controlling the White House, Senate, and House. According to a US Securities and Exchange Commission filing, these funds will be listed on May 5, as confirmed by Bloomberg ETF analyst James Seyffart. The funds in question are the Roundhill Democratic President ETF, Republican President ETF, Democratic Senate ETF, Republican Senate ETF, Democratic House ETF, and Republican House ETF.

While the House and Senate products are tied to the outcome of the November 3, 2026 elections, the presidential products focus on the November 7, 2028, election. Exposure is gained through swap agreements referencing binary event contracts traded on CFTC-regulated markets, with these contracts settling at $1 if the predicted outcome occurs and $0 if it does not. A warning in the prospectus states that if the targeted party fails to win, the fund will lose nearly all its value.

Roundhill has opted not to terminate the funds after settlement. Instead, once the market prices a winner above $0.995 or below $0.005 for five consecutive trading days, the fund will treat the outcome as decided and transition into the next cycle, which includes the 2028 House and Senate exposure for the midterm funds and the 2032 presidential race for the other funds. The prospectus notes that if the market is later proven incorrect, there will be no recourse for shareholders.

Other companies, such as Bitwise and GraniteShares, have filed similar proposals, with Bitwise using a 'PredictionShares' brand. However, their structures differ, as Bitwise's funds will terminate shortly after each outcome is determined, whereas GraniteShares and Roundhill will roll into the next election. Although political event contracts are already traded on prediction markets like Polymarket and Kalshi, wrapping them in ETFs could increase accessibility by allowing them to be held in ordinary brokerage accounts and certain retirement accounts. This development follows the CFTC's withdrawal of a Biden-era proposal that would have banned political event contracts, despite ongoing challenges from state regulators in Massachusetts, New York, Nevada, and other states.

Roundhill has also filed to list non-political prediction market ETFs tied to the likelihood of the US entering a recession, as reported by Bloomberg ETF analyst Eric Balchunas.
