France blocks access to Polymarket website due to gambling concerns

France has blocked access to Polymarket’s website, escalating what has been a slow-moving regulatory confrontation between one of crypto’s most popular prediction markets and one of Europe’s most active gambling regulators.

The move by the Autorité Nationale des Jeux (ANJ), France’s gambling authority, effectively bars French residents from accessing the platform. It’s the culmination of an investigation that began in late 2024, when the regulator started questioning whether Polymarket’s operations amounted to unlicensed gambling under French law.

How we got here

That user, known publicly as “Théo” or by the handle Fredi9999, became the focal point of ANJ’s scrutiny in early November 2024. The trader’s massive profits from election-related prediction contracts raised uncomfortable questions for French authorities about whether their citizens were essentially gambling on a platform operating without local authorization.

Polymarket’s initial response was measured. In December 2024, the platform restricted French users to view-only mode, meaning they could browse markets but couldn’t place new trades.

The platform characterized this as a “proactive approach to compliance” while it engaged with local stakeholders.

A continent-wide pattern

France isn’t acting in isolation here. Polymarket is now blocked or restricted in over 33 countries worldwide, with a heavy concentration across Europe. The Czech Republic has implemented similar restrictions.

The platform operates on-chain, initially built on Polygon, and has evolved its collateral system over time. But none of that technical architecture matters much when a national regulator decides your product is simply unlicensed gambling wearing a blockchain costume.

The platform surged in popularity during the 2024 US election cycle, becoming a go-to source for real-time political probability assessments, with trading volumes hitting unprecedented levels.

What this means for investors

For anyone with exposure to prediction market platforms or tokens associated with this sector, France’s action is a warning flare. When over 33 countries have restricted a single platform, it stops being an isolated regulatory hiccup and starts looking like a structural risk for the entire category.

The risk for Polymarket specifically is that losing access to major European markets erodes its liquidity advantage. Prediction markets are only as useful as the volume they attract, because thinner markets produce less reliable probability estimates. Each country that blocks access removes potential participants, which makes the platform marginally less valuable for everyone still using it.
