Polymarket to challenge French ban in court after regulator blocks access

Polymarket plans to challenge France's decision to block access to its platform after the country's gambling regulator instructed internet service providers to restrict access. The legal dispute highlights the growing debate over how prediction market platforms should be regulated and whether they should be treated as financial trading services or online gambling operators.

The case has attracted significant attention because it raises broader questions about digital prediction markets, blockchain-based platforms and the legal frameworks that govern emerging technologies. At the centre of the disagreement is whether users participating in event prediction markets are engaging in financial forecasting or gambling under French law.

Regulatory scrutiny intensifies in France

France's gambling regulator, the Autorité Nationale des Jeux (ANJ), instructed internet service providers on July 16 to block access to Polymarket across the country. The regulator concluded that the platform operates as an unauthorized gambling service rather than a regulated financial marketplace.

According to the regulator, French internet users were still able to access parts of the platform despite earlier restrictions on trading activity. Although financial transactions had reportedly been prevented for users in France since late 2024, authorities maintained that continued access to prediction markets and live probabilities remained inconsistent with French gambling legislation.

The regulatory action reflects France's broader approach toward protecting consumers and ensuring that gambling services operate only under approved licensing frameworks.

Polymarket prepares legal challenge

Polymarket confirmed that it intends to contest the website block before the French courts. The company argues that the restriction is disproportionate because it had already taken measures to prevent trading activity by users located in France.

According to the company, French users have been unable to execute trades since late 2024. Remaining access was reportedly limited to viewing publicly available prediction markets without the ability to participate financially.

Polymarket believes the regulator's decision also affects individuals who use the platform for informational purposes only. The company says many visitors access prediction markets to monitor collective expectations surrounding political events, economic developments and sporting competitions rather than to trade.

The legal proceedings are expected to focus on whether providing access to publicly available market information should be treated differently from facilitating financial participation.

Why France considers the platform illegal

French authorities have maintained that accessibility alone may contribute to promoting an unauthorized gambling service.

The ANJ stated that even if users could no longer place trades, the platform continued displaying active markets, probabilities and event outcomes. In the regulator's assessment, this visibility continued encouraging interest in an activity that had not been authorized under French gambling legislation.

The regulator also reported that the platform continued attracting substantial online traffic from within France.

Official figures indicated more than 578,000 website visits generated by over 205,000 unique French users during June. Those statistics were cited as evidence that the platform remained widely accessible despite previous restrictions on transactions.

French authorities also noted that potential financial penalties associated with non-compliance could reach €100,000 under applicable enforcement measures.

Different views on prediction markets

A central issue in the dispute concerns the legal classification of prediction markets.

Prediction markets allow participants to buy and sell positions linked to the likelihood of future events. These events may include elections, financial developments, sporting contests, entertainment awards or other publicly verifiable outcomes.

Supporters often describe prediction markets as information aggregation tools because market prices can reflect the collective expectations of participants. Critics argue that many users participate primarily for speculative purposes, making the activity functionally similar to gambling.

French regulators formally classified prediction markets as illegal gambling in February 2026. That determination forms the legal foundation for the current enforcement action against Polymarket.

Polymarket rejects the gambling classification

Polymarket disputes the regulator's interpretation of its business model.

The company describes its platform as a decentralized prediction market operating through blockchain technology. Rather than acting as the counterparty to customer positions, the platform states that users trade directly with one another through peer-to-peer markets.

According to Polymarket, it does not take positions on market outcomes or generate revenue based on which prediction proves correct. Instead, it argues that the platform serves as infrastructure enabling market participants to exchange positions.

From the company's perspective, this structure distinguishes prediction markets from conventional gambling operators that accept wagers and assume financial risk against customers.

The legal challenge is therefore expected to examine not only how the platform operates technically but also how those operational features should be interpreted under existing French law.

Consumer protection remains a regulatory priority

French regulators have also expressed concerns regarding consumer protection.

Authorities have pointed to the absence of safeguards commonly required within regulated gambling markets. These protections may include self-exclusion programmes, spending controls, deposit limits and other responsible gambling measures designed to reduce gambling-related harm.

The regulator has indicated that prediction market platforms offering speculative financial participation without equivalent protections may expose users to similar risks found in traditional gambling environments.

Polymarket has maintained that its services should not automatically be assessed under gambling regulations because of their distinct market structure and technological framework.

The disagreement illustrates how regulators worldwide continue evaluating whether existing gambling legislation adequately addresses blockchain-based prediction markets.

A broader debate beyond France

The French case may have implications extending beyond one national market.

Prediction market platforms have attracted increasing attention from regulators in several jurisdictions as participation continues growing. Different countries have adopted varying approaches, with some treating prediction markets as financial products while others evaluate them under gambling legislation or derivatives law.

Legal outcomes in France could influence future discussions across Europe regarding the appropriate regulatory framework for blockchain prediction markets.

The dispute also demonstrates the challenges policymakers face when applying legislation originally developed for traditional gambling or financial services to newer decentralized technologies.

Regardless of the court's eventual decision, the case is likely to contribute to ongoing international discussions about innovation, consumer protection and regulatory consistency.

Conclusion

Polymarket's decision to challenge France's website block marks another important chapter in the evolving regulation of prediction markets. While the company argues that its blockchain-based platform functions as a peer-to-peer forecasting marketplace, French regulators continue to view the service as unauthorized gambling under national law.

The forthcoming legal proceedings are expected to examine complex questions surrounding digital markets, consumer protection and regulatory interpretation. Their outcome may help clarify how prediction market platforms should be treated under existing legislation while potentially influencing future regulatory approaches in other jurisdictions. As prediction markets continue expanding globally, legal certainty will remain an important consideration for operators, regulators and users alike.
