The SEC Blocks 24 ETFs Related to Prediction Markets on the Eve of their Launch

The SEC has just abruptly stopped the launch of 24 revolutionary ETFs. Expected this week, these funds were to provide access to prediction markets to millions of investors. A surprising halt that raises major questions !

Unique ETFs stopped just hours before launch

In February 2026, three major asset management companies filed their applications with the Securities and Exchange Commission (SEC). These are Roundhill Investments, Bitwise, and GraniteShares. Their goal: to launch the first ETFs directly exposed to prediction markets.

According to the current rule, an exchange-traded fund automatically becomes active after 75 days of filing, unless there is an explicit intervention from the U.S. regulator. This deadline falls precisely this week. The SEC has therefore made a last-minute decision. It suspends these launches to request additional information on :

• the mechanics of the products;
• transparency towards investors.

According to an ETF analyst at Bloomberg, the first ETFs were supposed to be released as early as Thursday, May 5. Roundhill had even set an official effective date. The halt is therefore as abrupt as it is unexpected.

The launch of these products has particular importance. Indeed, they would have allowed retail investors to access (via a traditional exchange) binary event contracts traded on platforms regulated by the CFTC, such as Kalshi. Practically speaking, each contract pays 1 dollar if the event occurs, 0 dollar otherwise.

ETFs exposed to elections, recession, and oil

The nature of the blocked products reveals the issuers’ ambitions. These ETFs do indeed cover a very wide spectrum:

• the results of the U.S. midterm elections (Senate and House of Representatives);
• the 2028 presidential election;
• the probability of an economic recession;
• layoffs in the technology sector;
• the exceeding of the $120 per barrel threshold for WTI crude oil.

Bitwise goes even further by filing ETFs linked to the price of Bitcoin and Ethereum. These products would thus have merged traditional finance and DeFi within a single regulated financial instrument.

The rise of these requests is no coincidence. In March 2026, the platforms Kalshi and Polymarket alone accumulated $24.3 billion in trading volume.

Analysis: prediction markets are no longer a niche. They attract both retail investors and institutions seeking to hedge their exposures on bonds, oil, or politically sensitive assets.

The SEC demands more transparency before any green light

The blocking of these ETFs does not mean a definitive rejection. Two sources close to the case cited by Reuters confirm that the delay is likely temporary. The SEC thus simply wants to better understand :

• how these exchange-traded funds structure their exposure to event contracts;
• how risks are communicated to investors.

Because the risks are real. Roundhill’s filings notably mention high risks related to insider trading on event contracts. More worryingly: in case of disputed results (whether a contested election or revised economic data), investors will have no recourse. In other words, losses are final.

Bitwise’s Chief Investment Officer Matt Hougan compares this situation to the first approval requests for Bitcoin ETFs : a lengthy but inevitable process. According to him, the industry is maturing quickly alongside its regulatory framework.

In any case, this blockage illustrates the tension between financial innovation and regulatory caution. The SEC is not closing the door on ETFs linked to prediction markets; it is opening it slightly with caution. The sector is holding its breath.
