The European Securities and Markets Authority has warned platforms that many prediction-market event contracts may already fall under existing EU restrictions, even when they are marketed as something other than derivatives. In a Friday public statement, ESMA said companies cannot avoid financial rules simply by calling binary-style products “event contracts.” The reminder targets products with binary outcomes and fixed payouts, which the regulator said are likely to qualify as financial instruments. The label is no longer the compliance shield, because ESMA is putting substance over branding at the center of the review.
Event contracts face a substance-over-form test
The regulator said contracts that meet the definition of financial instruments are already prohibited from being marketed, distributed or sold to retail investors under national measures implementing ESMA’s 2018 binary-options restrictions. That point is important because the statement does not create a new ban. It instead tells platforms that an existing retail prohibition may already apply to products now expanding under prediction-market language. The regulatory perimeter is being redrawn through interpretation, not fresh rulemaking, which makes the warning operationally urgent for platforms testing consumer-facing event contracts across Europe.
ESMA also drew a line around professional and institutional access. Even if retail investors are excluded, offering qualifying event contracts to those clients still requires authorization under the EU’s Markets in Financial Instruments Directive, or MiFID II. That means a platform cannot solve the problem merely by changing its customer category. The contract’s payout structure, financial-instrument status and authorization pathway remain central. Rebranding derivatives as event contracts does not remove licensing obligations, and that is the practical message for firms hoping to expand prediction markets inside the EU without first obtaining proper permissions.
The warning lands as prediction markets are expanding quickly and regulators are becoming less patient with semantic arbitrage. ESMA said it issued the statement after observing increased offerings of event contracts and rapid growth across the category. The issue is also escalating in the United States, where state gaming regulators and the Commodity Futures Trading Commission are fighting over whether event contracts should be treated as gambling or federally regulated derivatives. By March, authorities in 11 states had acted against platforms including Kalshi and Polymarket. The global question is becoming jurisdictional control, as regulators decide who gets to define prediction markets.
