Polymarket said on July 22, 2026 that it will challenge France's nationwide block of its website in the French courts, six days after the country's gambling regulator ordered internet service providers to cut off access to polymarket.com.
The order was signed on July 16 by the president of the Autorité nationale des jeux, France's gambling authority, which named Adventure One QSS Inc. as the site's operator. Since March 2022 the ANJ's president has been able to have a site blocked administratively, without asking a judge first, under the powers that rewrote Article 61 of France's gambling law of May 12, 2010. Those orders are made under the supervision of the administrative courts, and that review is the door Polymarket now says it will walk through. Under French law, promoting an unlicensed gambling site carries a penalty of up to 100,000 euros.
The number behind the order
Polymarket switched off trading for users in France in November 2024, after the regulator opened a review of the platform. The audience did not leave. In June 2026 the site drew 578,751 visits from 205,057 unique visitors in France, and those are the figures the ANJ put at the center of its decision. A further warning followed in February 2026. The regulator's conclusion was that cutting off payments had not settled anything: the French traffic was still arriving, and it was still being shown a live board of prices.
That board is what the order actually targets. In the regulator's words, the homepage "dynamically displays real-time odds for various events open to betting" and so "serves as a major channel for disseminating and promoting Polymarket's offerings, even though the site's operations are not authorized in France." Its other objections were about the machinery a French licensee is required to have and the site does not: no identity verification, no self-exclusion register, no stake limits, no place in the national responsible-gaming system.
A tampered thermometer at Charles de Gaulle
The regulator also had a live manipulation case to point at. On April 6 and April 15, 2026 the temperature readings used to settle Polymarket's Paris weather contracts jumped far above the surrounding conditions, reaching 22 degrees Celsius on a day when nearby readings pointed to about 18. Two wallets were positioned for exactly that. One turned a stake of less than $30 into $13,990 on an outcome the market had priced at roughly 0.2%; another turned $119 into more than $21,000 on an 18 degree threshold priced near 0.5%.
Météo-France, the national weather service, said that after physical findings on one of its instruments and an analysis of the sensor data it filed a complaint for interference with the operation of an automated data processing system with the air transport gendarmerie at Roissy. The Paris prosecutor's cybercrime unit opened an investigation on May 4, 2026. Polymarket moved its Paris temperature reference to Le Bourget airport, but the contracts that settled on the disputed readings were never cancelled or refunded. The tampering case and the missing identity checks both appear in the blocking decision.
Polymarket's answer: a price page is not a casino
Polymarket's public reply came on July 22. It said it was "disappointed by the French gaming authority's (ANJ's) sudden decision to unilaterally block our website" and that it intends "to challenge this decision through the legal process in France." It called the measure disproportionate, on the ground that trading from France had already been off since November 2024, so what the block removes is reading rather than trading: "most people come to Polymarket solely to learn the probability of future events." The company added that it holds no position in any market and does not profit from any outcome, and that it is in dialogue with the cybercrime unit of the Paris public prosecutor's office.
That is the question the administrative judge will be handed. Not whether trading was allowed in France, because it was already switched off, but whether a page that displays probabilities is itself advertising for an unlicensed gambling service.
Europe closes, America opens
France is not acting alone. Ukraine blocked the site in January 2026, Argentina in March and Spain in May, while Italy's regulator has ordered access cut twice. Brazil, India, Indonesia and Romania have restricted it in one form or another. The United States moved the other way over the same period: after buying the licensed derivatives exchange QCEX for $112 million, Polymarket was cleared by the Commodity Futures Trading Commission on November 25, 2025 to operate as a regulated US exchange.
Outside France, nothing changes today. What is at stake is the template. If a French court upholds an order that treats a page of probabilities as gambling promotion, every other European regulator inherits a tested tool. If it does not, the line between a market and a betting shop gets drawn somewhere the platform can live with. Worth keeping straight while the case runs: a contract price is the crowd's live estimate of how likely something is, not a tip, and the argument in Paris is about who gets to decide what that page legally is.
