The French National Gaming Authority (ANJ) has officially directed domestic internet service providers (ISPs) to block user access to the decentralized prediction platform Polymarket. This regulatory action follows an extensive investigation by the ANJ into the platform's operations, concluding that Polymarket's betting activities constitute unlicensed gambling under French law.
Why is the French regulator targeting decentralized frontends now?
The ANJ's decision represents a tactical shift in how sovereign regulators approach decentralized applications (dApps). Because smart contracts deployed on permissionless blockchains like Polygon cannot be easily shut down or altered by state authorities, regulators are increasingly targeting the centralized infrastructure layers—specifically domain registrars and domestic ISPs—to restrict access for regional users.
Under the French Internal Security Code, any organization offering betting services to French residents must secure prior authorization and adhere to strict consumer protection and taxation frameworks. Polymarket, which operates globally without regional licenses or mandatory KYC verification for basic access, has drawn scrutiny due to its rising popularity among European retail traders.
“By targeting the DNS and ISP level, European regulators are demonstrating that they do not need to control or dismantle underlying smart contracts to restrict regional market access,” notes Marc-Antoine Ledieu, a European Web3 compliance attorney. “This enforcement strategy sets a challenging precedent for other decentralized platforms operating without local regulatory clearance in the EU.”
The table below highlights the operational friction between French regulatory requirements and Polymarket's decentralized model:
| Regulatory Requirement | French Gambling Law (ANJ) | Polymarket Operational Model |
|---|---|---|
| Licensing | Mandatory state-issued authorization | Unlicensed, globally accessible |
| Identity Verification | Strict KYC and age verification | Wallet-based pseudonymous access |
| Taxation | Direct levies on gaming revenues | No automated state tax withholding |
| Enforcement Target | Local operators and domestic domains | Decentralized smart contracts on Polygon |
How does this regulatory action affect European DeFi users?
While the ISP-level block prevents average French users from accessing Polymarket via standard web browsers, it does not stop the underlying smart contracts from executing on the blockchain. Technically proficient users can still interact with the platform using Virtual Private Networks (VPNs), alternative DNS resolvers, or IPFS-hosted frontends.
However, the regulatory ban is expected to significantly reduce retail participation from France, as casual users face higher technical barriers to entry. This move could also signal a broader regulatory crackdown across other European jurisdictions, especially as the Markets in Crypto-Assets (MiCA) regulation continues to tighten oversight on digital asset service providers across the European Union.
