France blocks prediction markets

TLDR

Frances gambling regulator has ordered internet providers to block access to crypto prediction platform Polymarket, effectively banning most real-money prediction markets for users in the country.

1. The ANJ classifies Polymarket-style sites as illegal gambling and has imposed a nationwide ISP geoblock with potential fines for unauthorized advertising.
2. Regulators point to addictive mechanics, insider trading risks, hacked data feeds, and weak identity checks as key reasons prediction markets are problematic.
3. For crypto users, France joins over 30 countries restricting Polymarket, and similar scrutiny could extend to other on-chain prediction platforms and EU level rules.

Deep Dive

1. Frances Regulatory Block

Frances gambling regulator Autorit Nationale des Jeux (ANJ) has ordered internet providers to block Polymarket, treating it as an illegal gambling site rather than a financial trading venue.

The block follows earlier steps since late 2024, when France banned transactions and limited French users to view-only, yet traffic still reached over 578,000 visits from French IPs in June 2026.

Advertising or displaying live odds from unauthorized prediction sites to French users can now trigger criminal penalties, with fines reported at up to about 114,000 USD for violations.

2. Why Regulators Are Worried

ANJ and other authorities argue that prediction markets share gambling-like addictive features without the usual protections such as stake limits and self-exclusion tools.

They also highlight outcome manipulation and insider use of information, including hacked weather sensors at Meteo France and a French trader reportedly shifting U.S. election odds with multimillion dollar bets.

Investigations have found weak or missing Know Your Customer checks, making it easier for insiders or bad actors to exploit contracts tied to politics, weather, and geopolitical events.

3. Impact On Crypto Prediction Markets

Frances move fits a wider pattern, with Polymarket now restricted in more than 30 jurisdictions, including Germany, Italy, Spain, Brazil, and several other countries that treat it as unlicensed gambling.

This raises the bar for any crypto prediction platform that wants mainstream access in Europe, pushing them toward formal gambling licenses or securities style regulation rather than purely on chain operation.

For crypto users, it is a signal that event based tokens and prediction contracts will increasingly be judged on consumer protection, data integrity, and licensing, not just decentralization.

Confidence: high because multiple regulator statements and independent media reports align on the facts.

Conclusion

Frances block on Polymarket shows how quickly prediction markets can move from a niche crypto use case to a regulatory target when gambling and manipulation risks emerge.

If more countries follow Frances interpretation, the long term viability of unlicensed, on chain prediction platforms will depend on whether they can add robust safeguards and work within formal regulatory frameworks.
