ESMA Warns Prediction Market Companies: Rebranding Binary Options Won’t Bypass EU Rules – CoinCentral

TLDR

• Europe’s securities regulator ESMA says prediction market contracts with binary outcomes are already banned for retail investors under EU rules dating back to 2018.
• The warning clarifies that rebranding a product as an “event contract” doesn’t change its legal classification — what matters is how the product works, not what it’s called.
• No new rules were introduced; ESMA said it issued the statement due to the rapid growth of prediction markets globally.
• Professional and institutional investors can still access these products, but only through firms with proper MiFID II authorization.
• The EU has no licensed prediction market platforms available to retail clients, locking out a market of roughly 450 million people.

The European Securities and Markets Authority issued a stark reminder to prediction market companies on July 3. If your product works like a binary option, it will be treated like one — no matter what you call it.

ESMA’s statement came as global prediction market trading volume has surpassed $50 billion per month. Crypto-native platforms have been a major driver of that growth, offering markets on everything from elections to central bank decisions.

The EU has had a ban on binary options for retail investors since May 2018. That ban was originally a temporary measure under the Markets in Financial Instruments Regulation. It was later made permanent by most EU member states through national legislation.

ESMA said the legal classification of a product depends on its characteristics, not its marketing label. A contract that offers a fixed payout based on whether a future event occurs fits the definition of a financial instrument, and is therefore subject to existing restrictions.

What This Means for Crypto Platforms

For crypto-based prediction market platforms, the implications are direct. Any platform offering binary-outcome contracts to retail users in the EU is in violation of existing financial regulations, regardless of whether transactions settle on a blockchain.

Polymarket, the largest crypto prediction market by volume, has already run into similar issues. The platform blocked US users following a 2022 settlement with the Commodity Futures Trading Commission. EU retail users now face their own access barriers.

ESMA did not name specific platforms in its statement. But the message was clear: the existing rules apply universally, and the prediction market boom does not create an exemption.

Professional and institutional investors are not banned outright. But firms wishing to offer these products to professional clients still need full MiFID II authorization — meaning the path to legal access in Europe comes with significant regulatory requirements.

The US Is Fighting a Different Battle

Across the Atlantic, prediction markets are caught in a separate legal dispute. State gaming regulators and the federal Commodity Futures Trading Commission are in direct conflict over who has the authority to regulate event contracts.

By March 2026, authorities in 11 states had taken legal or regulatory action against platforms including Kalshi and Polymarket. Nevada temporarily blocked Kalshi’s operations, while Arizona filed criminal charges against the company.

In April, the CFTC declared exclusive federal jurisdiction over prediction markets. The agency sued several states and filed court briefs in support of platforms like Kalshi.

The conflict escalated further. On June 30, a Massachusetts judge allowed state authorities to file an amended complaint against Kalshi, alleging its sports contracts constitute illegal gambling under state law.

Tribal gaming groups and labor organizations have urged Congress to amend proposed legislation to explicitly prohibit sports-related event contracts on prediction market platforms.

Legal experts say the dispute could ultimately reach the US Supreme Court.

For now, Europe remains entirely closed to retail prediction market access, and the US regulatory picture stays unsettled.
