The CEO of X, Linda Yaccarino, said on Wednesday she would step down from her role, ending a two-year term at the Elon Musk-owned social media platform.
Yaccarino became chief executive in June 2023, months after Musk completed his $44 billion acquisition of the company, then known as Twitter. She was brought in to oversee business operations, while Musk focused on product and technology.
“I’m immensely grateful to him for entrusting me with the responsibility of protecting free speech, turning the company around, and transforming X into the Everything App,” Yaccarino said in a post on X. “I’m incredibly proud of the X team – the historic business turnaround we have accomplished together has been nothing short of remarkable.”
Musk replied, “Thank you for your contributions.”
Yaccarino said they began by prioritizing user safety, especially for children, and worked to restore advertiser trust.
“This team has worked relentlessly from groundbreaking innovations like Community Notes, and, soon, X Money to bring the most iconic voices and content to the platform. Now, the best is yet to come as X enters a new chapter with @xai,” she added.
During her time as CEO, X introduced a new video tab, expanded fact-checking features, and worked to increase ad revenue. The company was on track to report its first year of advertising growth since the 2022 acquisition.
Before her appointment, the platform experienced major changes.
In April 2022, Musk made an offer to buy Twitter for $43 billion, paused the deal in May, and attempted to terminate it in July. The company sued Musk, and he completed the purchase in October 2022.
In November 2022, mass layoffs were announced, affecting several key teams. Musk renamed the platform X in July 2023 and introduced a new logo.
In November 2023, Musk endorsed an antisemitic post, prompting many advertisers to leave the platform. X later filed an antitrust lawsuit in August 2024 against the World Federation of Advertisers and several companies, accusing them of organizing a boycott.
In March 2025, Musk’s AI company xAI acquired X in an all-stock deal that valued the platform at $33 billion.
Yaccarino did not give a specific reason for her resignation.
