Polymarket is preparing to contest a nationwide website block in France after the country’s regulator said the platform continued to promote illegal gambling. The dispute puts fresh attention on how prediction markets are treated under national gambling rules and how regulators view platforms tied to trading on real-world outcomes.

According to the regulator’s position, the service raises concerns that go beyond basic access. French authorities pointed to risks linked to user losses, identity checks and the possibility of market manipulation, framing the platform as a service that could expose consumers to harms typically associated with gambling activity.

Polymarket, however, is drawing a clear distinction between its model and that of a traditional betting operator. The company said it does not take the opposite side of customer trades and does not profit based on the result of the events being traded. That argument is central to its response, as it seeks to separate prediction-market trading from a system in which an operator sets odds and bets directly against users.

The challenge in France could become an important test of how regulators classify these platforms and what standards they must meet to operate. It also highlights the broader debate over whether markets built around forecasting outcomes should be regulated like financial trading venues, gambling services or something in between.
