Authorities in Argentina have ordered a nationwide block on Polymarket. The move targets unlicensed financial and betting-related services operating in the country.
The case was brought by the City of Buenos Aires Lottery, known as LOTBA. It also received support from the casino group CASCBA. Prosecutors argued the platform operates like a betting system.
Officials said users stake funds on yes-or-no outcomes linked to events. These include politics, inflation, and global developments. They stated the platform lacked strong identity and age verification systems.

Authorities also noted that accounts could be opened within minutes. Funding methods included crypto assets and credit cards. This raised concerns about access by minors and vulnerable users.
The case drew attention after market activity related to inflation data. Trading patterns appeared before official figures were released by INDEC. Prosecutors did not base the case on this issue but noted it increased scrutiny.
Vietnam Moves to Restrict Overseas Crypto Platforms
In Vietnam, authorities are preparing new rules targeting offshore crypto platforms. The plan aims to limit access to foreign exchanges and services used by local users.
Officials are working to tighten control over digital asset transactions. The focus is on platforms that operate without local registration. Authorities want to bring more activity under domestic supervision.
The proposed measures may include blocking access to overseas platforms. They may also require local licensing for crypto service providers. This approach seeks to improve monitoring and compliance.
Vietnam has seen steady growth in crypto adoption. However, regulators have expressed concern about risks linked to unregulated services. These include fraud, money laundering, and weak consumer safeguards.
Global Shift Toward Stronger Crypto Oversight
The actions in Argentina and Vietnam reflect a broader regulatory trend. Governments are increasing oversight of crypto platforms and related services.
In the United States, the U.S. Securities and Exchange Commission is advancing its crypto framework. The effort aims to define rules for digital asset markets.
At the same time, Morgan Stanley is pushing forward with a Bitcoin exchange-traded fund. This shows continued interest from large institutions.
Meanwhile, Nasdaq has approval for a tokenization settlement pilot. The program explores blockchain use in securities transactions.
