BUDAPEST/LISBON. The regulatory perimeter around decentralized prediction markets collapsed further this week as authorities in Hungary and Portugal ordered immediate access blocks against Polymarket. The coordinated restrictions signal a rapid closure of the European market for the Peter Thiel-backed platform, which saw volumes explode to $3.5 billion during the 2024 U.S. elections.
The Hungarian Blockade
On Monday, Hungarian users attempting to load the platform were met with a regulatory seizure notice. The country’s Supervisory Authority for Regulated Activities (SZTFH) issued decision SZTFH-0325927, classifying the platform’s operations as illegal, unlicensed gambling.
The move is not merely a warning; it is a network-level block enforced by local ISPs. While the SZTFH labeled the measure as "temporary" pending a final legal review, the regulator’s precedent with offshore betting sites suggests a permanent ban is the likely outcome. Local reporting from local reporting confirmed the ban targets both the primary domain and associated subdomains.
Portugal: The Election Trigger
Simultaneously, Portugal’s Gaming Regulation and Inspection Service (SRIJ) moved to shut down access following a surge in speculative activity surrounding the country’s own presidential election. Regulators cited concerns over "unlicensed gambling operations" after observing over €5 million in bets placed on domestic political outcomes, activity the SRIJ flagged for potential insider trading risks.
The European Domino Effect
The dual bans reinforce a hostile trend across the continent. Polymarket is now effectively fenced out of major EU jurisdictions, with regulators refusing to accept the "event contract" nomenclature used to bypass U.S. CFTC rules.
- France: The National Gaming Authority (ANJ) geo-blocked the site in December 2024 after a French trader known as "Théo" profited $80 million from U.S. election bets.
- Poland & Belgium: Both have placed the domain on their respective blacklists for offering unlicensed derivatives.
Institutional Context
The crackdown forces a critical re-evaluation of the decentralized betting thesis. While Polymarket operates on the Polygon blockchain (making funds technically seizure-resistant), its reliance on centralized web interfaces for retail adoption makes it vulnerable to this exact vector of DNS and ISP-level censorship. Without a front-end, liquidity from casual users dries up, leaving only sophisticated actors willing to interact directly with smart contracts.
