The ban, introduced on January 17, 2026, provides Portugal to a rising listing of over 30 nations blocking the platform amid mounting issues about insider buying and selling.
The Election That Triggered the Ban
Portugal’s playing regulator, the Serviço de Regulação e Inspeção de Jogos (SRIJ), took motion after customers wagered greater than €103 million ($120 million) on the January 18 presidential election. What caught regulators’ consideration was the timing and scale of bets positioned simply earlier than outcomes grew to become public.
The betting patterns raised pink flags. Within the hours main as much as the announcement, odds for Socialist candidate António José Seguro shifted dramatically from round 60% within the morning to over 90% by early night—effectively earlier than official exit polls have been launched. Seguro finally gained the primary spherical with roughly 31% of votes and can face far-right candidate André Ventura in a February Eight runoff.

SRIJ officers acknowledged that Polymarket operates with out a license and permits political betting, which is strictly unlawful in Portugal. Underneath the nation’s 2015 on-line playing legislation, solely sports activities betting, on line casino video games, and horse racing are permitted. Betting on political occasions—whether or not home or worldwide—is banned.
A Sample of Suspicious Buying and selling
The Portugal incident will not be remoted. Polymarket has confronted multiple insider trading controversies in latest weeks which have intensified regulatory scrutiny worldwide.
Probably the most dramatic case occurred on January 3, 2026, when an nameless dealer revamped $400,000 by betting on Venezuelan President Nicolás Maduro’s removing from energy. The dealer positioned bets price $32,000 simply hours earlier than U.S. forces captured Maduro. Three digital wallets collectively profited over $630,000 from this occasion, in accordance with blockchain analytics.
The timing appeared too good to be coincidence. The account that made the biggest revenue was created lower than every week earlier than the raid and solely positioned bets associated to Maduro and Venezuela. This prompted U.S. Consultant Ritchie Torres to introduce laws banning federal staff from buying and selling on prediction markets after they have personal info.
Simply days later, Polymarket appropriately predicted 26 out of 27 Golden Globe Award winners—a 96% accuracy price that raised extra eyebrows. The platform had partnered with the awards present to show stay betting odds in the course of the broadcast. Critics questioned whether or not somebody had insider entry to voting outcomes earlier than they have been introduced publicly.
Europe Closes Its Doorways
Portugal joins a wave of European nations blocking Polymarket. Hungary has already carried out a nationwide block, redirecting customers to an official warning web page. France and Switzerland banned the platform in late 2024. Poland, Belgium, Italy, and Germany adopted with their very own restrictions in early 2025.
Most lately, Ukraine added Polymarket to its nationwide ban registry in December 2025, particularly criticizing the platform for permitting bets on outcomes associated to the Russian invasion. Romania blacklisted the service in November after discovering over $600 million in transactions in the course of the nation’s elections.
The sample is obvious: European regulators view Polymarket as unlicensed playing, not a professional info market. Portugal’s Nationwide Workplace for Playing defined that “whether or not you wager in lei or crypto, in the event you wager cash on a future final result, underneath the situations of a counterparty wager, we’re speaking about playing that should be licensed.”
The Regulatory Divide
Whereas Europe is cracking down, Polymarket lately secured approval to return to U.S. markets after a three-year ban. The platform bought a CFTC-licensed trade for $112 million in July 2025 and acquired regulatory clearance in November 2025.
Nonetheless, this federal approval hasn’t stopped state-level challenges. Tennessee ordered Polymarket, together with rivals Kalshi and Crypto.com, to halt sports activities betting contracts on January 9, 2026. Connecticut issued comparable orders in December 2025, although a federal choose briefly blocked enforcement.
The central authorized query is whether or not federal commodities regulation overrides state playing legal guidelines. With circumstances scheduled for February 2026, the courts will quickly determine if prediction markets can function underneath one set of federal guidelines or should adjust to 50 completely different state legal guidelines.
What Occurs Subsequent
For Portuguese customers, the ban creates fast issues. SRIJ warned that after the platform is blocked, customers might not have the ability to recuperate their funds. Solely licensed operators present client protections, and Polymarket has no such license in Portugal.
The platform remained accessible on Monday, January 20, however regulators are making ready to order web service suppliers to dam entry. Customers trying to bypass restrictions with VPNs would violate Polymarket’s phrases of service and danger account closure.
The broader implications prolong past Portugal. A Columbia College examine printed in November 2024 discovered that roughly 25% of Polymarket’s buying and selling quantity got here from wash buying and selling—when merchants purchase and promote to themselves to create pretend exercise. Throughout high-stakes occasions like elections, that determine reportedly spiked to 60%.
Polymarket’s CEO Shayne Coplan has defended the platform, arguing it gives “readability the place there’s confusion.” The corporate reached an $8-9 billion valuation in October 2025 after receiving funding from Intercontinental Alternate, which owns the New York Inventory Alternate. The platform processed over $18.1 billion in buying and selling quantity all through 2025.
The Crossroads of Innovation and Regulation
Portugal’s ban highlights the basic rigidity round prediction markets. Are they revolutionary forecasting instruments that combination info by means of monetary incentives? Or are they merely unlicensed playing platforms dressed up with blockchain know-how?
With 34 nations now blocking entry and legislative battles intensifying in the USA, Polymarket faces a important take a look at. The platform should show it could actually function inside regulatory frameworks whereas sustaining the options that drove its explosive development. For now, the partitions are closing in from a number of instructions, and the trail ahead stays unsure.
Portuguese regulators have made their place clear: political betting is illegitimate, whatever the know-how used. As extra nations attain comparable conclusions, the prediction market trade should adapt or danger changing into inaccessible to a lot of the world.
