The SEC has just stopped the launch of 24 revolutionary ETFs. Expected this week, these funds were to give access to prediction markets to millions of investors. A surprise stoppage that raises major questions!
In brief
- The SEC blocked the launch of 24 ETFs linked to prediction markets.
- The issuers affected are Roundhill, Bitwise and GraniteShares.
- These ETFs were expected after a regulatory period of 75 days.
- The SEC is demanding more details on product mechanics and transparency.
- The delay is described as temporary according to sources close to the matter.
New ETFs stopped a few hours before launch
In February 2026, three large management companies file their files with the Securities and Exchange Commission (SEC). These are Roundhill Investments, Bitwise and GraniteShares. Their objective: 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 deposit, unless express intervention by the American regulator. This deadline falls precisely this week. The SEC therefore took a last minute decision. It suspends these launches to request additional information on:
- product mechanics;
- transparency towards investors.
According to an ETF analyst at Bloomberg, first ETFs were to be released on Thursday, May 5. Roundhill had even set an official effective date. The halt is therefore as brutal as it is unexpected.
The launch of these products is of particular importance. In fact, they would have allowed individual investors to access (via a traditional stock exchange) binary event contracts traded on platforms regulated by the CFTClike Kalshi. Concretely, each contract pays 1 dollar if the event occurs, 0 dollars otherwise.
ETFs exposed to elections, recession and oil
The nature of blocked products reveals the ambition of the issuers. These ETFs cover a very broad spectrum:
- the results of the American mid-term elections (Senate and House of Representatives);
- the 2028 presidential election;
- the likelihood of an economic recession;
- layoffs in the technology sector;
- exceeding the threshold of $120 per barrel of 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 the same regulated financial instrument.
The rise of these requests is no coincidence. As of March 2026, the Kalshi and Polymarket platforms alone have a combined trading volume of $24.3 billion.
Decryption: the prediction markets are no longer a niche. They attract both individual investors and institutional investors seeking to hedge their exposures to bonds, oil or politically sensitive assets.
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 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. The Roundhill files notably mention high risks associated with insider trading on event contracts. More worrying: in the event of a disputed result (whether a disputed election or a revision of economic data), investors will have no recourse. In other words, the losses are permanent.
Bitwise Chief Investment Officer Matt Hougan compares this situation to first requests for approval of Bitcoin ETFs : a long, but inevitable process. According to him, the industry is maturing rapidly alongside its regulatory framework.
In any case, this blockage illustrates the tension between financial innovation and regulatory prudence. The SEC is not closing the door to ETFs linked to prediction markets, it is opening it carefully. The sector is holding its breath.
