Executive Summary

The French regulatory crackdown on Polymarket has significantly altered the landscape for prediction markets in Europe, but it has not yet resulted in a clean migration of volume to decentralized alternatives. Instead, the market is characterized by regulatory arbitrage via VPNs and a slow shift toward infrastructure-level protocols like Azuro.

Executive Summary

France’s Autorité Nationale des Jeux (ANJ) formally banned Polymarket on February 25, 2026, following the high-profile "Théo" incident where a French trader profited approximately $80 million on the 2024 U.S. election [Source: https://www.websearch.com/result1]. While Polymarket remains the dominant player with 70-80% market share, French users are increasingly caught between using VPNs to access Polymarket's superior liquidity or moving to decentralized protocols like Azuro, which are harder to block at the application level.

1. The French Regulatory Action

The ban was catalyzed by the lack of a French gambling license and the massive, unregulated capital flows identified during the 2024 U.S. election cycle.

• Trigger: The trader "Théo" (Fredi9999) placed bets totaling between $28M and $40M, drawing intense scrutiny to the platform's compliance framework [Source: https://www.websearch.com/result1].
• Enforcement: As of July 2026, France is one of over 40 countries (including Germany and the UK) where Polymarket is restricted. While geo-blocking is active, it is widely bypassed via VPNs, creating a "grey market" estimated at 5.4 million illegal players in France as of 2025 [Source: https://www.websearch.com/result1].

2. Comparison of Alternatives

Volume migration is currently fragmented. While Polymarket maintains the highest liquidity, decentralized protocols (DEXs) and regulated competitors are capturing specific niches.

3. Barriers to Volume Migration

Several structural factors prevent a wholesale move from Polymarket to decentralized alternatives:

• Liquidity Concentration: Polymarket’s dominance (70-80% of all volume) creates a "liquidity moat." Traders prefer the tighter spreads on Polymarket, even if it requires a VPN, over smaller DEXs like Augur or Gnosis, which currently show negligible volume [Source: https://www.websearch.com/result2].
• Product Mismatch: Regulated alternatives like Kalshi are heavily skewed toward sports (87% of volume in March 2026), whereas French users have historically shown more interest in the political and macro markets that Polymarket specializes in [Source: https://www.websearch.com/result2].
• Infrastructure vs. Frontend: Protocols like Azuro are seeing growth (5 million transactions by mid-2026) because they act as a liquidity layer for multiple frontends, making them more resilient to single-jurisdiction bans [Source: https://azuro.org].

4. Risks and Market Outlook

The migration of French volume is largely "invisible" in official statistics because it remains on Polymarket via unauthorized access or has moved to unindexed offshore DEXs.

• Security Warnings: Community reports suggest caution regarding RAIN and Anon due to unverified security audits. Additionally, SX Network has been flagged on community "avoid" lists despite its presence in the prediction market sector.
• Future Outlook: The ANJ's ban may inadvertently drive users toward more opaque, fully decentralized protocols that offer even fewer consumer protections than Polymarket's hybrid model.

Conclusion: While the ban has restricted official access, it has not yet driven a significant, measurable shift to decentralized alternatives. Most French volume likely remains on Polymarket via VPNs due to the platform's unmatched liquidity, though infrastructure protocols like Azuro are positioned as the long-term beneficiaries of increased regulatory pressure.
