Linda Yaccarino has resigned from her role as CEO of X, the social media platform formerly known as Twitter. Her departure ends a two-year effort to rebuild the company’s advertising business while contending with Elon Musk’s constant involvement and public controversies. Yaccarino was hired in June 2023 to stabilize X’s relationship with advertisers and give the company a more business-focused presence. Instead, she became the face of damage control.
A longtime advertising executive who spent over a decade at NBCUniversal, Yaccarino brought deep ties to Madison Avenue and a reputation for delivering results. She was seen as a strategic hire who could help Musk gain the trust of an ad industry wary of the platform’s direction. That optimism faded quickly as advertisers continued to exit X, citing brand safety concerns and Musk’s unpredictable behavior. Within months, it became clear that Yaccarino did not hold full control.
A Public Role Without Real Authority
Although she was nominally in charge of X’s business operations, Musk retained authority over product decisions, platform strategy, and public messaging. He announced the company’s name change without consulting her and often undercut her messaging with late-night posts. In interviews, Yaccarino sometimes appeared out of the loop, reinforcing the perception that her authority was limited. One staffer told Business Insider simply, “Elon is in charge.”
Advertisers were not reassured. Multiple brand safety incidents pushed major companies like Disney and IBM to leave the platform. In one high-profile case, a report revealed that their ads appeared next to extremist content. Musk’s response to the advertiser backlash included public insults and dismissive comments. Yaccarino responded with a staff memo praising Musk’s candor, but the damage was already done.
Legal Escalations and Internal Undermining
In 2024, X escalated tensions with the ad industry further by filing a lawsuit against major advertisers. The suit accused brands of coordinating a boycott, a charge experts said lacked legal grounding. Still, the threat of litigation unsettled agencies and discouraged open criticism of the platform. Some marketing firms advised clients to maintain small ad buys on X to avoid potential retaliation.
The strain continued to build. In March 2025, Musk’s artificial intelligence company xAI acquired X through an all-stock transaction. That move reduced Yaccarino’s position to that of a division head under Musk’s broader corporate umbrella. Later, Musk hired a new chief financial officer, bypassing the executive she had put in place. Internally, these moves signaled a shift in power and a growing sense that her role had been diminished.
Grok Fallout and Shrinking Ad Revenue
Yaccarino’s exit also follows renewed criticism of the company’s AI chatbot, Grok. Earlier this week, users shared screenshots of the bot making offensive comments, including a bizarre invocation of Adolf Hitler. X acknowledged the incident and removed the content, but the fallout echoed earlier controversies. As with past scandals, the responsibility to manage external relationships often fell on Yaccarino.
During her tenure, she oversaw new video products, brokered a digital wallet deal with Visa, and helped keep the user base relatively stable. X remains significantly larger than Threads and Bluesky in terms of daily active users. Yet ad revenue continued to decline, and the business did not recover to pre-Musk levels. The World Advertising Research Center estimates that X’s ad revenue shrank by nearly 23% during her time as CEO, while the global social media ad market grew by over 34%.
End of an Unstable Role
Former colleagues and analysts have noted that Yaccarino entered the role with strong credentials but little real authority. She was often the public face of a company she did not fully control, forced to explain decisions she did not make. In many cases, she absorbed the fallout for Musk’s actions, even as her influence waned.
By the time she resigned, the outcome appeared inevitable. According to sources close to her, she had always planned to walk away when the time was right. With mounting failures and diminishing leverage, that moment has arrived.
Was Linda Yaccarino ever truly in control of X, or was her resignation inevitable from the start?
