TLDR
- ESMA, the European Union’s securities watchdog, has confirmed that prediction market products delivering binary results remain prohibited for retail traders under regulations established in 2018.
- The regulatory guidance emphasizes that product function, not marketing terminology, determines legal classification — calling something an “event contract” doesn’t alter its regulatory status.
- ESMA’s announcement introduces no additional regulations; the statement responds to the explosive worldwide expansion of prediction market platforms.
- Institutional and professional traders maintain access to these instruments, but only via properly authorized MiFID II-compliant firms.
- Currently, no prediction market platforms operate with licenses permitting retail client access in the European Union, effectively excluding approximately 450 million potential users.
On July 3, the European Securities and Markets Authority delivered an unambiguous message to prediction market operators. The regulator made clear that functional characteristics, not creative naming conventions, determine whether a product falls under existing prohibitions.
ESMA’s intervention arrives amid unprecedented growth in prediction market activity, with monthly trading volumes now exceeding $50 billion globally. Blockchain-based platforms have fueled much of this expansion, creating markets spanning political elections, monetary policy decisions, and countless other future events.
Since May 2018, the European Union has maintained a comprehensive prohibition on binary options for non-professional investors. Initially implemented as a temporary restriction under the Markets in Financial Instruments Regulation framework, the ban subsequently gained permanent status through domestic legislation in most member nations.
According to ESMA, a product’s regulatory treatment hinges entirely on its structural features rather than its promotional description. Any instrument providing predetermined payouts contingent upon specific future outcomes qualifies as a financial instrument and consequently faces applicable regulatory constraints.
What This Means for Crypto Platforms
Cryptocurrency-based prediction market operators face straightforward consequences. Platforms delivering binary-outcome products to EU retail customers violate current financial regulations, irrespective of blockchain settlement mechanisms.
Polymarket, currently commanding the largest share of crypto prediction market volume, has encountered comparable regulatory obstacles previously. After reaching a 2022 agreement with the Commodity Futures Trading Commission, the platform restricted American user access. European retail traders now confront similar accessibility limitations.
While ESMA’s statement avoided naming individual platforms, its implications were unmistakable: current regulatory frameworks apply comprehensively, and rapid industry growth provides no regulatory exemption.
Professional and institutional market participants aren’t completely barred from participation. However, companies seeking to serve professional clients must obtain comprehensive MiFID II authorization — establishing that legitimate European market access requires substantial regulatory compliance.
The US Is Fighting a Different Battle
Meanwhile, American prediction markets face an entirely separate jurisdictional controversy. State gaming authorities and the federal Commodity Futures Trading Commission are engaged in a fundamental dispute over regulatory authority for event-based contracts.
By March 2026, regulatory or legal challenges had emerged from authorities in 11 states targeting platforms including Kalshi and Polymarket. Nevada imposed temporary operational restrictions on Kalshi’s activities, while Arizona prosecutors pursued criminal proceedings against the company.
In April, the CFTC asserted exclusive federal regulatory authority over prediction markets. The agency initiated lawsuits against multiple states while submitting supporting legal briefs on behalf of platforms such as Kalshi.
Tensions continued escalating. On June 30, a Massachusetts court permitted state regulators to submit revised complaints against Kalshi, claiming its sports-related contracts violate state gambling statutes.
Tribal gaming authorities and labor organizations have lobbied congressional representatives to modify pending legislation to explicitly ban sports-focused event contracts on prediction market platforms.
Legal analysts suggest this jurisdictional conflict may eventually require US Supreme Court resolution.
Currently, European retail investors remain completely excluded from prediction market participation, while American regulatory frameworks remain in flux.
