Elon Musk announced that the social media platform X will make its new algorithm publicly available, including all code related to organic and advertising post recommendations, in seven days.

"This will be repeated every four weeks, with comprehensive developer notes to help you understand what has changed," he stated in a post on X.

Earlier this week, the European Commission decided to extend a retention order previously sent to X last year, concerning algorithms and the spread of illegal content, now extended until the end of 2026, as spokesperson Thomas Regnier told reporters on Thursday.

In July 2025, Paris prosecutors launched an investigation into the social media platform over suspected algorithmic bias and fraudulent data extraction. Musk's X dismissed the investigation as a "politically-motivated criminal investigation" that undermines users' free speech.

Last month, the European Union fined X 120 million euros ($140 million) for breaching transparency obligations under the bloc's Digital Services Act. The fine was related to X's "blue checkmark" subscription, lack of transparency regarding its ad repository, and failure to grant researchers access to the platform's public data.

Musk responded with an obscene remark under a European Commission post about the fine.
