Spain’s stock market regulator CNMV fined X 5 million euros for failing to verify that a crypto advertiser had investment services authorisation, as part of Spain’s tightened crypto-advertising rules.

The violations stem from a March 2023 regulation requiring platforms to better control financial product advertising, verify advertisers aren’t on illegal lists, and confirm they are authorised to offer services.

Ads in question claimed that Quantum AI could generate large profits through stock or crypto investments and used impersonations of public figures to boost credibility.

Industry reaction notes Europe’s tightening stance on crypto regulation, with debates on balancing investor protection and innovation and calls for platforms to act as vigilant gatekeepers.

The development is framed as part of growing crypto regulation in Europe, signaling regulators’ tougher approach rather than hype.

The broader impact could see crypto firms and platforms tightening compliance and risk disclosures in retail marketing, slowing aggressive cross-border campaigns and pushing more responsible ads.

The decision contributes to scrutiny of X under Europe’s Digital Services Act for content moderation and ad-verification obligations.

X did not immediately respond to comment requests.

Consumers should see clear risk warnings and advertiser authorisation status in such ads and verify registration to avoid promises of quick gains.

The case marks a key moment in Spain’s crypto-advertising regulation and signals broader European tightening, demanding more transparent campaigns.
