Why France Blocked Polymarket — and What It Means for EU Traders

On July 16, 2026, the president of France's national gambling regulator ordered French internet service providers to block access to Polymarket's website. The Autorité Nationale des Jeux (ANJ) did not accuse Polymarket of manipulating a market or defrauding traders. It classified the platform as an illegal gambling operator.

Polymarket said it would challenge the decision, according to Reuters. The block is therefore a regulatory action with a live legal dispute attached, not a final criminal finding.

The case matters beyond France because it shows how differently European regulators treat event contracts. France does not regulate Polymarket as a financial exchange. It regulates it as an unlicensed gambling site.

What France did, and when

The ANJ's attention dates to November 2024. The regulator examined polymarket.com, concluded that the services could be unauthorised gambling, and contacted the site's Panama-based publisher, ADVENTURE ONE QSS INC. After that intervention, Polymarket introduced a geoblock intended to prevent bets being placed from French territory.

The ANJ says that geoblock was circumvented in practice. In February 2026 it went further, publishing a general position that prediction-market platforms are not authorised in France and are considered illegal gambling sites. It warned that the products have addictive features similar to regulated gambling, but without the protections of the licensed market: no bet limits, no time limits and no identity checks to verify age.

On July 16, 2026, the ANJ's president used the regulator's administrative blocking power against the website. The order was published the next day. The ANJ said the site had 578,751 visits and 205,057 unique visitors from France in June 2026 alone. It also said it blocked 1,290 URLs in 2025, a figure it uses to show that Polymarket is being treated like other illegal operators rather than singled out.

The legal theory is gambling, not securities

France's online gambling market is a licensed, closed system. The ANJ says prediction-market platforms are not part of it. That is the core of the case.

Two consequences follow. First, offering unauthorised gambling is a criminal offence in France. The ANJ's 2024 notice cited a maximum of three years in prison and a €90,000 fine, rising to seven years and €200,000 for organised activity. Second, advertising an unauthorised site is itself an offence punishable by a €100,000 fine. The ANJ argued that Polymarket's homepage, which displays live odds, functions as promotion of an illegal offer.

The regulator also raised integrity concerns. It said some weather bets appeared to have been rigged and that weather sensors may have been hacked. A Paris prosecutor's cybercrime unit opened an investigation on May 4, 2026, entrusted to the Office for Combating Cybercrime. That investigation is separate from the licensing dispute, and no court has made a finding in it.

The ANJ additionally said the platforms available to French and European users lacked a know-your-customer system to verify users' integrity. That is a gambling-compliance argument, not a markets argument.

What was actually blocked

The order was addressed to internet service providers and targeted access to the Polymarket website. It did not purport to seize the underlying on-chain contracts, and it did not shut down Polymarket's global exchange.

That distinction matters. A DNS block makes the site harder to reach from a French connection. It does not make the contracts disappear. The ANJ itself says the earlier transaction geoblock was circumvented. VPNs, alternative front ends and mobile applications can all change what a determined user sees.

The practical result is a cat-and-mouse enforcement model. France can make Polymarket harder to reach and can threaten advertisers. It cannot easily police a self-custodial, crypto-settled venue at the protocol level.

The wider EU picture

There is no single EU licence for prediction markets. Gambling is regulated nationally, and the ANJ lists a growing set of countries that have restricted or blocked Polymarket: Germany, Belgium, Romania, Switzerland, the Netherlands, Poland, Greece, Cyprus, Ukraine and Portugal, among others. Its July 2026 notice also named Italy, Spain and the Czech Republic.

The approaches differ. Some regulators treat event contracts as gambling. Some treat them as financial derivatives. Some have no settled position. A platform that is legal in one member state can be blocked in the next, and a licence in one country does not passport into another for gambling purposes.

For traders, that means "Europe" is not a single access category. The relevant question is the country of residence, the country of the user's IP address, and sometimes the country where the payment is processed. Polymarket's own terms and geoblocking list are the first place to check; the ANJ's blacklist is the French-specific source.

What traders should know

Three risks are worth separating.

The first is legal risk. Using a VPN to access a site that the ANJ has ordered blocked does not change the regulator's view of the offer. It may also breach Polymarket's terms. The ANJ has warned that players on illegal sites face non-payment of winnings, payment fraud, data capture and malware. Those warnings are generic to unlicensed gambling, but they are the regulator's stated position.

The second is enforcement risk. Polymarket is challenging the French order. If it wins, the block could be suspended or narrowed. If it loses, the block could be extended or reinforced. The litigation status is part of the access question, not a footnote.

The third is market risk. A blocked website does not mean a resolved market is invalid. The contracts settle on-chain according to their rules. But a French user who cannot access the interface may have difficulty trading out of a position, claiming a payout or documenting a dispute. Access risk and resolution risk are different things, and both matter.

France's action is best understood as a gambling-licensing decision with cross-border effects. It does not prove that Polymarket manipulated anything. It does show that the platform's legal status in Europe depends on which regulator is looking, and that a single national regulator can make a large platform disappear from a national internet connection in a single order.
