Background on Elon Musk and Twitter

Twitter, now known as X, was fined 5 million euros ($5.8 million) by Spain’s securities regulator for failing to ensure that a crypto asset firm advertising on the platform was authorized to provide investment services. The fine, dated November 3, was published on Thursday in the Boletín Oficial del Estado.

Elon Musk, the CEO of SpaceX and Tesla, acquired Twitter in October 2022. His involvement with the platform has made this regulatory action noteworthy, as his influence and following could potentially impact the crypto industry’s self-regulation.

Regulatory Context and Actions

In 2022, Madrid took steps to regulate the “reckless advertising of crypto assets” by assigning the Comisión Nacional del Mercado de Valores (CNMV) to examine mass campaigns and ensure investors were aware of the risks involved.

CNMV’s Decision

According to the official document, “The CNMV decided to impose a fine on Twitter International Unlimited Company… for failing to fulfill its duty of assistance towards the CNMV by verifying if Quantum AI was authorized to provide investment services by the CNMV and whether Quantum AI was not listed as an entity cautioned by the CNMV or foreign supervisory bodies.”

Details of the Fine and Next Steps

The fine, amounting to 5 million euros (approximately $5.8 million), was imposed on X (formerly Twitter) for not ensuring that Quantum AI, a crypto asset firm advertising on its platform, was authorized to provide investment services by the CNMV.

X did not respond immediately to a request for comment sent via email. The company can appeal the decision before the Audiencia Nacional de España.
