Polymarket Officially Banned in France: The Gambling Regulator Takes Action

France has just cut off access to Polymarket, the blockchain-based prediction market platform. The country’s national gambling regulator has made its ruling: the site is illegal on French territory.

This decision comes at a time when Polymarket is posting record financial performance, surpassing $1 billion in annualized revenue. A paradox that perfectly illustrates the growing tension between the rise of decentralized prediction markets and European regulatory frameworks.

Behind this block lie serious accusations: market manipulation, insider trading risks, and circumvention of gambling laws. Here is what we know.

Why Has France Blocked Polymarket?

The Autorité Nationale des Jeux (ANJ) — France’s national gambling authority — is behind the decision. The regulator considers that Polymarket operates as an unlicensed gambling platform on French soil, in direct violation of the applicable legal framework. Without a license issued by the ANJ, no platform of this kind can legally offer its services to French residents.

The grievances go well beyond a simple lack of authorization. The regulator also points to structural risks inherent to Polymarket’s model: the ability for actors with privileged information to place bets on events before their public announcement constitutes, according to the ANJ, a real risk of insider trading and market manipulation. These accusations echo past controversies, particularly around betting on elections and major geopolitical events.

In practice, French users attempting to access Polymarket now run into a block at the Internet Service Provider level. The site is inaccessible without using a VPN — a practice that remains in a legal grey area for individual users.

Polymarket Hits $1 Billion in Annualized Revenue: A Block That Comes at the Worst Time

The irony of the timing has not been lost on industry observers. Polymarket is crossing the symbolic $1 billion annualized revenue milestone at the very moment one of Europe’s most significant markets is shutting its doors to the platform. Polymarket had already seen an explosion in its profile during the 2024 US presidential election, attracting millions of users worldwide.

This French block could set a precedent across Europe. Other national regulators are closely watching the evolution of decentralized prediction markets, a rapidly expanding segment that still largely escapes traditional regulatory frameworks. The central question remains unanswered: is a blockchain-based prediction market a financial instrument, a form of gambling, or an entirely new category of its own?

For Polymarket, the stakes extend well beyond France. If other European countries follow the ANJ’s lead, the platform could find itself locked out of a market representing hundreds of millions of potential users. This kind of regulatory pressure could force the platform to open discussions with authorities — or to restructure in order to obtain local licenses, a process that is both lengthy and costly.

Decentralized Prediction Markets: What Future in the Face of Regulation?

The Polymarket case shines a light on a broader challenge facing the entire DeFi ecosystem. Decentralized protocols, borderless by nature, are running headlong into national regulations designed for centralized, geographically identifiable actors. The ANJ can block access at the DNS and ISP level, but it cannot alter the smart contract running Polymarket on the blockchain.

This technical reality creates a regulatory paradox: the service remains technically accessible via circumvention tools, but using it becomes legally risky for French residents. Savvy users will likely continue to access it, while the general public will be effectively shut out — a partial outcome that rarely satisfies either side.

Other prediction market platforms, such as Augur and Azuro, are watching this case closely. It implicitly defines the conditions under which these protocols will — or will not — be able to operate legally in Europe in the years ahead. The regulatory battle over prediction markets is only just beginning.
