The SEC is pumping the brakes on prediction market ETFs, and it wants to hear what you think before deciding whether to let them through the door.

SEC Chair Paul Atkins has opened a public comment period on prediction market ETFs, a new category of exchange-traded funds that would let investors bet on real-world events like elections and corporate layoffs. Over two dozen such products have been proposed by issuers including Roundhill Investments, GraniteShares, and Bitwise Asset Management. None of them have launched. The SEC has delayed every single one, requesting additional information about how they actually work and what protections exist for investors.

What are prediction market ETFs, and why does the SEC care?

Think of prediction markets as organized, financial-grade betting. Platforms like Polymarket already let users wager on whether specific events will happen, from presidential elections to Federal Reserve rate decisions. Prediction market ETFs would wrap that same concept into a familiar Wall Street package: a fund you can buy and sell through a brokerage account, just like an S&P 500 index fund or a gold ETF.

The appeal is obvious. Prediction markets exploded in popularity during the 2024 US election cycle, and asset managers want to ride that wave into regulated financial products. Roundhill, GraniteShares, and Bitwise are all racing to be first to market.
