ESMA warns prediction markets are binary options in disguise, banned for retail investors since 2018

Decentralized finance is looked at askance in Europe by regulatory authorities. The financial watchdogs do not hide it and multiply warnings. In this area, ESMA intends to deprive crypto traders of a tool nevertheless prized by investors. These are bets on the future, contracts that allow speculation on events. The European regulator has just reminded that these products, if financial, are already banned for retail investors.

ESMA: event contracts caught in the crosshairs of binary options restrictions

On July 3, 2026, ESMA published a statement that caused a bombshell effect in the world of predictive markets. The regulator reminds that binary outcome prediction contracts are very likely financial instruments under MiFID II. Marketing them under the name “event contracts” does not change their legal qualification.

“The commercial name provided by companies (for example “event contracts”) is irrelevant for categorization under MiFID II of products distributed, marketed, or offered to clients“, warns ESMA in its statement. In other words, calling a cat a cat does not turn it into a dog.

Restrictions on binary options, adopted in 2018 and transposed into national laws, therefore already apply to these products. 

Event contracts with a binary outcome and binary payment are likely derivatives which are financial instruments, and likely fall under product intervention measures.

ESMA thus puts an end to ambiguities in uncertainty finance.

Prediction platforms in the sights of European finance watchdogs

Polymarket, Kalshi, Myriad are familiar names for fans of futures betting and crypto. These platforms could well disappear from European screens if they do not comply. ESMA insists on the obligation for companies to conduct a thorough legal analysis of their products.

If the contract covers a financial underlying listed in Annex I of MiFID II, it is a financial instrument. Distribution to retail clients is then prohibited. Distribution to professionals remains possible but requires MiFID II authorization. 

Distribution of these event contracts, even if only to non-professional clients, requires this authorization.

Platforms will have to revise their offerings or request authorizations to continue operating. Some might try to seek refuge under betting status governed by national gaming laws. 

But ESMA warns: prediction contracts can also be qualified as bets or crypto-assets regulated by MiCA. European regulation leaves little room for arbitrariness in finance.

A legal grey area that raises questions about the future of prediction markets

The legal qualification of prediction contracts remains unclear, and this is the core problem. Contracts covering political, sporting, or cultural events are not necessarily financial instruments. They do not cover a financial underlying listed in the regulation. 

This legal vacuum creates unequal treatment between platforms and insecurity for investors.

ESMA does not create new rules but clarifies an existing framework in view of the rapid growth of prediction markets. The regulator notes an increased supply of these contracts and rapid market expansion. 

This clarification could slow innovation in Europe, while the United States is experiencing a regulatory battle. The dialectic is deeply troubling for observers: on one side, protective regulation; on the other, a risk of innovation fleeing. 

The regulator’s ethic is to protect retail investors, but at what cost to finance and crypto?

Key dates of the regulation

• 2018: ESMA bans binary options for retail investors;
• July 3, 2026: ESMA extends this ban;
• MiFID II: any distribution to professionals requires authorization;
• MiCA: token contracts can be regulated crypto-assets;

Prediction markets enter a zone of regulatory turbulence. The EU is considering expanding ESMA’s powers for stronger regulation. The finance of uncertainty will have to reckon with guardians of traditional finance.
