A Buenos Aires court has ordered the blocking of the Polymarket platform in Argentina. Google and Apple have been instructed to remove the service's mobile app from their stores, according to local media.
The ruling was made by Judge Susana Parada at the request of the capital's gambling regulator. Officials found that Polymarket lacked a license to operate in this jurisdiction.
Prosecutors concluded that the site functioned as a "hidden online betting system." Polymarket did not verify users' identities or ages, allowing accounts to be created in minutes, which provided minors with unrestricted access to contracts.
Investigators also noted that the use of cryptocurrencies for transactions on the platform allowed users to bypass regulatory oversight required for the gambling sector.
The national communications regulator, ENACOM, has been directed to require internet service providers to block access to the site nationwide.
Authorities were also drawn to trades related to inflation levels in Argentina. Before the official February report was released, analyst forecasts ranged from 2.6% to 2.8%. However, just 20 minutes before the release, Polymarket's quotes sharply shifted to 2.9%, with the volume of bets on the corresponding contract rising to $91,000. Observers speculated that this could be linked to insider information leaks.
Pressure on prediction markets is increasing globally: access to Polymarket has been restricted in Portugal, the Netherlands, Germany, and Romania.
It is worth noting that in November 2025, media outlets reported the platform's return to the U.S. market, albeit in beta mode.
