Prediction market ETFs set to debut, opening brokerage accounts to election bets

A new class of exchange-traded funds designed to let investors bet on US election outcomes is expected to hit the market as soon as next week – which could bring prediction market exposure into ordinary brokerage accounts and self-directed retirement plans for the first time.

New York-based Roundhill Investments filed a post-effective amendment with the Securities and Exchange Commission on Tuesday, setting a new effective date of May 5 for six funds that would track party control of the White House and Congress. Bloomberg ETF analyst James Seyffart noted the filing on social media, writing that "we are going to see prediction markets ETFs launch next week."

The six funds from Roundhill – whose recently launched DRAM memory ETF rocketed to $1 billion in AUM just days after launching – cover Democratic and Republican outcomes across the presidency, Senate, and House. The congressional funds are tied to the November 2026 midterm elections, while the presidential funds reference the 2028 race.

Competing issuers Bitwise and GraniteShares also submitted similar filings earlier this year, and Seyffart expects those products to launch around the same time.

The ETFs would gain exposure through swap agreements linked to binary event contracts traded on Commodity Futures Trading Commission-regulated markets. Each fund is structured to deliver capital appreciation if the targeted party wins the relevant election – and a near-total loss if it does not. SEC filings across all three issuers include a warning that a contrary outcome means the fund "will lose substantially all of its value."

The issuers differ in how they handle post-election periods. Roundhill and GraniteShares plan to roll exposure into the next election cycle once markets price in a near-certain result, while Bitwise intends to terminate its funds shortly after outcomes are decided.

GraniteShares founder and chief executive William Rhind drew a comparison to earlier ETF expansions. "One of the best expressions of the ETF is providing market access to different investments in an ordinary brokerage account," he told CNBC, adding that "when added in ETF form, the underlying markets have benefitted" historically.

Bitwise chief investment officer Matthew Hougan pointed to the bitcoin ETF as a relevant precedent, noting that many investors keep their assets in brokerage accounts and that those products gave millions access to crypto without needing to open an exchange account.

Event contracts already trade on platforms such as Polymarket and Kalshi, which together recorded $24.3 billion in combined volume in March. The ETF structure would allow those exposures to be held in standard brokerage accounts, including some retirement accounts, without requiring a separate platform login.

The regulatory backdrop remains unsettled. The CFTC withdrew a proposed ban on political event contracts in February and has since begun a formal rulemaking process, publishing an advance notice asking the public how such contracts should be governed. State regulators in Massachusetts, New York, Nevada are still challenging those types of contracts in court.

Separately, prediction market contracts tied to sports events are the subject of ongoing litigation at the state and federal level, with tribal governments also contesting their legality with respect to tribes' sovereign right to regulate gambling on their lands.

Bloomberg senior ETF analyst Eric Balchunas commented at the time of Roundhill's initial filing that the product, if approved, would "[open] up a huge door to all kinds of stuff."
