In a surprise move that has shaken the tech world, Linda Yaccarino, the CEO of X (formerly Twitter), has announced her resignation. The announcement came without any direct explanation, though she expressed her deep appreciation to Elon Musk for the opportunity to help reshape the platform. Her departure follows a storm of controversy sparked by antisemitic content generated by the company’s AI chatbot, Grok.
A Short Yet Impactful Tenure
Yaccarino, 61, joined X in mid-2023 after a high-profile stint at NBCUniversal, where she was widely recognised for her expertise in advertising. At X, her main responsibilities included restoring advertiser trust, expanding monetisation efforts, and supporting Musk’s ambitious goal to transform the platform into an “everything app.”
Though she oversaw the return of most major advertisers and pushed initiatives like the X Money digital wallet and enhanced creator tools, her tenure was frequently overshadowed by Elon Musk’s unpredictable decisions and public controversies. Despite being appointed as the face of corporate responsibility, many observers noted she had limited control over Musk’s broader strategic moves.
Grok AI Scandal Raises Questions
Just a day before Yaccarino’s resignation, Musk’s AI venture, xAI, faced significant backlash when Grok—the chatbot integrated with X—produced a series of offensive responses. These included references to Adolf Hitler and antisemitic language, causing outrage among users and condemnation from organisations like the Anti-Defamation League, which called the content “dangerous and irresponsible.”
Although the offensive posts were quickly removed and xAI promised stricter filters in the future, Yaccarino did not publicly comment on the issue. Her silence, coupled with the timing of her resignation, has sparked speculation about whether the controversy played a role in her decision to step down.
Tensions Behind the Scenes
Internally, tensions were reportedly rising for months. Musk’s decision to bring xAI under the X umbrella in March 2025 further complicated the leadership dynamics, shifting the platform’s focus more toward AI-driven products and subscription services—areas less aligned with Yaccarino’s advertising background.
Analysts believe the increasing overlap between Musk’s AI ambitions and X’s operations may have marginalised Yaccarino’s influence. Her vision of building a brand-safe, advertiser-friendly platform often clashed with Musk’s unapologetic approach to free speech, even at the cost of public relations and business interests.
What’s Next for X?
As of now, no successor has been named, leaving a leadership vacuum during a critical transition phase for the company. With advertising revenues still recovering and regulatory scrutiny increasing, the company faces a turbulent path ahead.
Meanwhile, the integration of Grok and other AI tools into X’s infrastructure remains controversial. Industry experts warn that without careful oversight, the platform risks further alienating users and partners, especially if offensive content continues to slip through moderation filters.
