Elon Musk Says X Will Open-Source Its Algorithm Amid EU Scrutiny

Elon Musk announced on Saturday that X, the social media platform formerly known as Twitter, will publicly release its recommendation algorithm, including the full code behind organic content and advertising post suggestions, within seven days. According to Musk, this transparency initiative will not be a one-time move. He stated that X plans to repeat the release every four weeks, accompanied by detailed developer notes explaining what has changed and why, aiming to provide clearer insight into how the platform’s algorithms function.

The announcement comes at a time when X is facing heightened regulatory pressure in Europe. Earlier this week, the European Commission confirmed it had extended a data retention order originally issued to X last year. The order, which focuses on algorithms and the spread of illegal content, has now been prolonged until the end of 2026, according to Commission spokesperson Thomas Regnier. The extension signals ongoing concerns from EU regulators about how social media algorithms influence content distribution and public discourse.

In addition to EU-level scrutiny, X has also faced legal challenges at the national level. In July 2025, Paris prosecutors launched an investigation into the platform over suspected algorithmic bias and alleged fraudulent data extraction. X strongly rejected the accusations, calling the probe a politically motivated criminal investigation that threatens freedom of speech and user rights.

Regulatory pressure intensified further last month when the European Union imposed a €120 million ($140 million) fine on X. EU regulators said the company violated transparency requirements under the Digital Services Act. The penalty was linked to several issues, including the platform’s “blue checkmark” subscription system, insufficient transparency in its advertising repository, and failure to provide researchers with adequate access to public platform data.

Musk responded defiantly to the fine, posting an obscenity in reply to a European Commission statement announcing the penalty. As X moves forward with plans to open-source its algorithm, the decision is widely seen as both a transparency effort and a strategic response to mounting regulatory and legal challenges in Europe.
