Argentina just drew a line in the sand between crypto and casinos. President Javier Milei’s government forwarded a package of four legislative proposals to Congress on May 22 that would prohibit banks, payment service providers, and virtual asset service providers from facilitating any transactions connected to unauthorized gambling operations.

What the bill actually does

The legislative package was developed in collaboration with Sedronar, Argentina’s agency focused on drug and addiction-related policy, and the Ministry of Health. The government is positioning this as a public health initiative, not just a financial regulation play.

The proposal makes it illegal for any financial entity, including crypto companies, to offer services to unauthorized gambling operators. The National Securities Commission, known by its Spanish acronym CNV, would be tasked with enforcing compliance among digital asset entities specifically. Argentina’s Law 27,739, enacted in March 2024, already mandated that VASPs register with the CNV, with full compliance expected by December 31, 2025.

This bill adds a new layer of obligation on top of that framework, requiring registered VASPs to actively screen for and block transactions linked to unlicensed gambling.

Argentina’s escalating crackdown on illegal gambling

In April 2026, authorities blocked 251 unlicensed gambling websites in Buenos Aires province alone. A month before that, in March 2026, Argentina imposed a nationwide restriction on Polymarket, the blockchain-based prediction market that gained global attention during the 2024 US presidential election. The platform was blocked for operating without a betting license.

The crypto-specific angle

For licensed VASPs operating in Argentina, compliance costs are about to go up. They’ll need to build or enhance transaction monitoring systems capable of identifying payments flowing to unlicensed gambling platforms. Since Law 27,739 established the VASP registration framework in 2024, the CNV has been steadily expanding its oversight toolkit. Adding anti-gambling compliance requirements is a natural extension of that trajectory.

What this means for investors

The immediate market impact of this bill is likely minimal as it still needs to pass through Congress. VASPs that already have robust KYC and transaction monitoring infrastructure will adapt more easily. Smaller operators without those systems may find the regulatory burden increasingly difficult to bear.

For Polymarket and similar prediction market platforms, every country that follows Argentina’s lead in classifying prediction markets as gambling creates another jurisdiction where these platforms face either licensing requirements or outright bans.
