French prosecutors have escalated their inquiry into Elon Musk and X into a criminal investigation, widening a case that already included allegations of algorithmic manipulation, improper data extraction, and harmful content on the platform. The move deepens a legal fight that has followed Musk’s company across Europe and adds fresh pressure on X’s leadership as regulators scrutinize how the platform operates inside France.
Paris prosecutors say the investigation began after complaints in 2025 raised concerns that X’s recommendation systems may have influenced political discourse in France. The case later expanded to examine whether the platform’s chatbot Grok helped generate or spread content such as Holocaust denial, sexually explicit deepfakes, and material involving non-consensual or abusive imagery. French officials have also looked at whether X knowingly facilitated the creation and distribution of such content.
According to reporting on the case, Musk and former X chief executive Linda Yaccarino were summoned for questioning on April 20, but neither appeared or cooperated with the interview request. Musk has previously rejected the allegations, calling the probe politically motivated and describing earlier enforcement actions as an attack. The French side has continued moving forward despite his objections.
The investigation has broader implications because it touches on how social media platforms manage algorithms, user data, and AI-generated content. It also reflects a wider regulatory pattern in which governments are testing whether major tech companies can be held responsible for content moderation failures, platform design choices, and possible violations of local law. X has already faced similar scrutiny in other jurisdictions, adding to the company’s legal and reputational burden.
There is also an international dimension to the dispute. Reports say the U.S. Department of Justice declined to assist French authorities, arguing that France was improperly interfering in an American company’s affairs. That leaves the case positioned not only as a criminal probe of X, but also as a test of how far national regulators can go when platform decisions and AI tools have cross-border effects.
