Who is in charge at the company formerly known as Twitter since Elon Musk took over?

More than two years have passed since Elon Musk bought social network Twitter for $44 billion in late 2022. Since then the company, now known as X, has seen its valuation plummet to about $9.4 billion in October 2024, though it also has brought Musk major strategic benefits by providing him with a massive communications platform to push forward the controversial political agenda of his close ally President Trump. But given that the billionaire is spending most of his time at the White House—while also running Tesla and four other companies—who is actually running X on a day to day basis? Here is an overview (you can also scroll down to the chart below):

In June of 2023, Musk named former NBC big-wig Linda Yaccarino as CEO of X and later, in November 2024, made another big hire when he tapped Mahmoud Reza Banki, who spent six years as CFO and chief strategy officer for streaming platform Tubi, to be X’s CFO.

Other notable X additions include Angela Zepeda, former chief marketing officer of HyundaiMotor America, who was named global head of marketing in the fall of 2024, and, in early 2025, John Nitti, a former Verizon executive, who was tapped to be global head of advertising innovation. X also saw some exits in 2024, with Renato Leite Monteiro and Ged Tarpey, both holdovers from the Twitter days, departing.

Like other Musk companies, X is unforthcoming with information and did not respond to requests for comment. Fortune relied on news reports, government documents and filings, as well as social media posts including LinkedIn and X, to compile its list of executives. Here are the top X execs we know, all of whom Fortune attempted to contact. Scroll further down to find links that reveal who is running Musk’s other operations, including DOGE.
