Key Takeaways
- ESMA has clarified that prediction market contracts featuring binary outcomes fall under the existing retail investor prohibition established by EU regulations in 2018.
- The regulatory body emphasizes that product classification depends on functionality, not marketing terminology — calling something an “event contract” doesn’t exempt it from financial regulations.
- This wasn’t a new regulatory measure; ESMA issued the clarification in response to the explosive worldwide expansion of prediction market platforms.
- Institutional and professional investors retain access to these instruments, provided they use firms holding appropriate MiFID II licensing.
- Currently, no prediction market platforms operating legally serve retail clients in the EU, effectively excluding approximately 450 million potential users.
On July 3, the European Securities and Markets Authority delivered an unambiguous message to prediction market operators: regulatory classification follows function, not branding. If your platform operates like a binary option, expect regulatory treatment as such.

This clarification from ESMA arrives amid unprecedented growth in the prediction market sector, with monthly global trading volumes exceeding $50 billion. Blockchain-based platforms have fueled much of this expansion, facilitating markets on topics ranging from political elections to monetary policy decisions.
Since May 2018, the EU has maintained a prohibition on binary options for retail participants. Initially implemented as a temporary restriction under the Markets in Financial Instruments Regulation, most EU nations subsequently codified the ban through domestic legislation.
According to ESMA, a product’s regulatory status stems from its underlying structure rather than its marketing presentation. Contracts providing predetermined payouts contingent on future event outcomes meet the criteria for financial instruments and consequently face established limitations.
Consequences for Blockchain-Based Platforms
The regulatory implications for cryptocurrency-powered prediction market operators are straightforward. Any platform providing binary-outcome instruments to European retail participants violates current financial regulations, irrespective of blockchain-based settlement mechanisms.
Polymarket, which dominates crypto prediction markets by trading volume, has previously encountered comparable regulatory obstacles. Following a 2022 agreement with the Commodity Futures Trading Commission, the platform restricted access for US-based users. European retail participants now confront similar accessibility limitations.
While ESMA refrained from identifying particular platforms, the regulatory position leaves no ambiguity: current regulations apply comprehensively, and the prediction market sector’s rapid growth doesn’t warrant special exemptions.
Professional and institutional market participants aren’t completely prohibited from accessing these products. However, firms seeking to provide these instruments to professional clients must obtain comprehensive MiFID II authorization — establishing that legitimate European market access demands substantial regulatory compliance.
America’s Separate Regulatory Conflict
In the United States, prediction markets face an entirely different regulatory challenge. State gaming authorities and the federal Commodity Futures Trading Commission remain locked in jurisdictional conflict over event contract oversight.
As of March 2026, regulatory or legal measures targeting platforms such as Kalshi and Polymarket had been initiated by authorities in 11 states. Nevada imposed temporary operational restrictions on Kalshi’s activities, while Arizona pursued criminal proceedings against the company.
The CFTC asserted exclusive federal authority over prediction markets in April. The agency initiated lawsuits against multiple states and submitted court documents supporting platforms including Kalshi.
The jurisdictional battle intensified significantly. On June 30, a Massachusetts court permitted state regulators to file an updated complaint against Kalshi, claiming its sports-related contracts violate state gambling prohibitions.
Tribal gaming interests and labor unions have lobbied Congressional representatives to modify pending legislation, seeking explicit prohibitions on sports-focused event contracts within prediction market platforms.
Legal analysts suggest this jurisdictional dispute may ultimately require US Supreme Court resolution.
Currently, European retail investors face complete market exclusion, while American regulatory frameworks remain in flux.
