The European Securities and Markets Authority just told the prediction market industry what it probably didn’t want to hear: calling your product an “event contract” instead of a “derivative” doesn’t make it legal to sell to retail customers in Europe.

ESMA issued a public statement on July 3 clarifying that prediction market products with binary outcomes, the yes-or-no bets that have become wildly popular on platforms like Polymarket, fall squarely under existing financial instrument regulations. And those regulations, specifically the ones banning binary options for retail clients, haven’t gone anywhere.

What ESMA actually said

The regulator’s position is straightforward. If a product offers a fixed payout based on whether a future event happens or not, its legal classification depends on the product’s underlying characteristics, not whatever creative label a company slaps on it in its marketing materials.

Binary options have been effectively banned for retail investors across the EU since May 2018, when ESMA first enacted a temporary prohibition under Article 40 of the Markets in Financial Instruments Regulation. That temporary measure proved popular enough that most EU member states adopted permanent national bans of their own.

The prediction market boom meets European regulation

Prediction markets have exploded in popularity over the past two years, with global monthly trading volume exceeding $50 billion. Crypto-native platforms have driven much of that growth, offering markets on everything from election outcomes to interest rate decisions to weather events.

Currently, there are no licensed prediction market platforms available to retail clients in the EU. That’s a notable gap, especially when compared to the US, where the CFTC has allowed regulated platforms like Kalshi to offer event contracts on certain topics, albeit with ongoing regulatory battles of their own.

Professional clients aren’t entirely shut out. ESMA acknowledged that firms could potentially offer these products to professional investors, but only with proper MiFID II investment-firm authorization and only if the products genuinely qualify under the professional-client framework.

What this means for crypto prediction platforms

For crypto-native prediction market platforms, the ESMA statement draws a clear line. Any platform serving EU retail users with binary-outcome contracts is operating in violation of existing financial regulations, regardless of whether transactions settle on a blockchain or through traditional infrastructure.

Polymarket, the largest crypto prediction market by volume, has already been navigating this patchwork. The platform blocked US users following a 2022 settlement with the CFTC, and European users face their own access questions. ESMA’s statement doesn’t name specific platforms, but the implication is universal: if you’re offering these products to European retail customers, you’re on the wrong side of the law.

For investors in prediction market tokens and platforms, the calculus shifts. Europe represents a massive addressable market that remains effectively off-limits. Any prediction market platform’s valuation thesis needs to account for a continent of roughly 450 million people where retail access is prohibited.
