The Autorité Nationale des Jeux (ANJ), France's national gambling regulator, confirmed the order publicly on July 17. The instruction requires French ISPs to block polymarket.com at the network level, a significant escalation from the voluntary geo-blocking Polymarket implemented after an earlier ANJ intervention in November 2024. The platform is operated by ADVENTURE ONE QSS INC., incorporated in Panama, which places it outside French licensing jurisdiction entirely.

The ANJ cited two grounds for the order. First, the platform lacks the consumer safeguards French law requires of licensed operators: no deposit limits, no identity verification, and no session-time controls. Second, the regulator referenced an active criminal investigation into what it described as evidence that "some wagers offered on the platform could be manipulated." France's online gambling regime limits licensed activity to sports betting, horse-racing, and poker; betting exchanges are prohibited outright, and prediction markets covering politics, economics, or geopolitics are illegal by definition regardless of whether an operator holds a licence. Under French law, providing unauthorised gambling services carries up to three years imprisonment and fines of 90,000 euros, rising to seven years and 200,000 euros when organised activity is involved.

The manipulation case the ANJ had in mind traces back to April 2026 and a temperature sensor at Charles de Gaulle Airport. A Météo-France sensor recorded an abrupt four-degree Celsius spike within 12 minutes, pushing the reading past the 22°C threshold that Polymarket used to resolve Paris weather bets. A trader who had placed unusually aggressive wagers on temperatures above 21°C, against an 18°C consensus forecast, collected roughly 30,000 euros. A second anomaly followed on April 19, with another approximately $20,000 claimed. Online speculation pointed to a hair dryer held near the sensor. Météo-France filed a formal criminal complaint under Article 323-2 of the French Penal Code, which covers alteration of automated data processing systems. Paris's dedicated cybercrime unit, the Office Anti-Cybercriminalité (OFAC), opened a formal investigation on May 4. Polymarket quietly shifted its Paris temperature resolution oracle to Paris-Le Bourget airport but did not cancel or refund the disputed bets.

The French ISP order arrives as Polymarket faces simultaneous scrutiny in the United States. In June 2026, the Commodity Futures Trading Commission opened a broad investigation following a Wall Street Journal exposé published on June 23, 2026, revealing that Polymarket had contracted primarily college-aged content creators to film fake trades on replica websites designed to mimic the live platform. About 1,105 promotional videos were reviewed; roughly 70 percent contained simulated trades. The content generated over 140 million views across TikTok, YouTube, and Instagram. Creators were paid between $2,000 and $3,000 per month and told not to disclose compensation. A Polymarket spokesperson said in June that the company was "conducting a comprehensive audit of active promotional content to ensure it complies with its standards, as well as applicable regulatory and legal disclosure requirements." The CFTC previously fined Polymarket $1.4 million in January 2022 for operating an unregistered swap execution facility. The company re-entered the U.S. market in November 2025 after acquiring QCEX, a CFTC-licensed derivatives exchange and clearinghouse, for $112 million.

The platform's scale makes the regulatory picture more significant. Total value locked on Polymarket reached approximately $514 million following a protocol upgrade in April 2026, according to DefiLlama data. Monthly trading volume peaked at $10.5 billion in March 2026. Cumulative nominal volume through April 28, 2026, crossed $61 billion across 1.3 million markets and 1.2 billion recorded trades, according to a database published on arXiv.

For users in South Asia and Africa, the French action is not a distant European development. India formally classified prediction markets as prohibited online money gaming under the Promotion and Regulation of Online Gaming Act 2025, which came into force on May 1. A blocking order against Polymarket followed on May 21. France and India are now part of a group of more than 34 countries that have banned or restricted the platform; seven of those acted in 2026 alone. Germany, the Netherlands, Belgium, Romania, Portugal, Ukraine, Hungary, Bulgaria, and Switzerland have all imposed some form of restriction. By contrast, Pakistan, Nigeria, and South Africa have not issued blocking orders. Nigeria currently hosts five live Polymarket prediction markets; the country's Securities and Exchange Commission has focused primarily on crypto asset trading regulation and has not yet targeted prediction markets specifically, which explains why access remains open even as the risk horizon for Nigerian users is narrowing. South Africa's National Gambling Board operates under a National Gambling Act that has not yet addressed decentralised prediction markets, leaving the legal status unresolved for South African users. Across Africa, 47 active markets are listed on the platform as of late June 2026. Kenya and Ghana, Sub-Saharan Africa's highest crypto-adoption markets, are the countries in the region considered most likely to face regulatory pressure next.

The deeper issue the French case surfaces is structural. Prediction markets depend on external data oracles to settle bets, and the Charles de Gaulle incident illustrates how those data feeds can become attack surfaces when financial incentives are large enough. ANJ president Isabelle Falque-Pierrotin, in a March 2026 address cited in industry analysis, described prediction markets as a regulatory arbitrage play that offers what amounts to betting without the consumer protections, responsible gambling controls, or tax obligations that licensed operators must maintain. With three simultaneous lines of legal pressure now converging on Polymarket, the broader question is whether the decentralised prediction market model can survive in any major regulated jurisdiction without fundamental changes to how it handles oracles, marketing, and licensing.
