In a decisive move, an Argentine court has ordered a nationwide ban on access to Polymarket, the popular prediction market platform, citing serious regulatory violations. The March 16, 2026 ruling directs national communications authority ENACOM to immediately block the platform and all its derivatives via every internet service provider across Argentina. With this decision, Argentina becomes the second country in Latin America, after Colombia, to institute a blanket ban on Polymarket.
Licensing and Data Security Concerns Prompt Action
The initiative to scrutinize Polymarket began with Buenos Aires’ Public Lottery Authority, known as LOTBA, which filed the original complaint. LOTBA alleged the platform operated in Argentina without proper licensing and failed to implement user safeguards such as age verification and identity checks, as mandated by national regulations. The court agreed, classifying Polymarket as an unlicensed, illegal online gaming service and thus subject to prohibition.
A major trigger for the rapid enforcement of the ruling was a high-profile data leak incident. Just fifteen minutes before Argentina’s national statistics agency INDEC released official inflation data, Polymarket published a prediction pegging inflation at 2.9 percent. This apparent leak of state-held economic data caused a public outcry and raised fears over the unauthorized disclosure of sensitive government information—spurring regulators to act swiftly.
Global Restrictions Tighten on Prediction Market Apps
Argentina’s ruling expanded beyond internet access barriers. Authorities ordered Polymarket’s apps to be removed from both Apple and Google stores in the country, effectively preventing users from bypassing browser-based blocks through alternative methods. This comprehensive approach seeks to close loopholes for would-be users attempting to circumvent the ban.
The clampdown on Polymarket extends well beyond Argentina. In recent years, major economies such as the United States, United Kingdom, France, Germany, and Australia have also imposed complete bans on Polymarket’s operations. In 2026, countries including Portugal, Hungary, and Ukraine joined them, enacting full prohibitions. In Latin America, Colombia set the precedent with its earlier restrictions on prediction markets.
Elsewhere, different measures are in place. For instance, users in Singapore, Poland, Thailand, and Taiwan are allowed to close out existing trades on Polymarket but barred from initiating new positions. These partial restrictions reflect a more cautious, controlled approach rather than outright bans, suggesting ongoing debates about the platforms’ nature and impact.
US Embraces Regulatory Rather Than Prohibitory Models
The growing list of countries restricting Polymarket has reignited debate around the accuracy and regulatory challenges of prediction markets. While nations like the US have curbed access, recent trends indicate a willingness to regulate these platforms within the framework of financial oversight, instead of enforcing outright prohibitions. This approach marks a contrast to the uncompromising stance adopted by Argentina, allowing for legal operation under supervision rather than simple exclusion.
As restrictions spread across more regions, Polymarket faces significant implications regarding trading volume and liquidity. The platform stands out for its real-time data and high accuracy in forecasting key events, especially economic indicators and elections. Nevertheless, ongoing uncertainty around their legal status—whether these services are classified as financial instruments or as gaming products—continues to underpin varied regulatory responses worldwide.
With the tally of countries imposing bans on Polymarket rising in 2026, questions are mounting over the platform’s ability to maintain its global presence. The availability of open markets remains crucial for sustaining its liquidity and ongoing operations, making remaining accessible regions vital for Polymarket’s prospects going forward.
