Anthony Armstrong named xAI CFO, bringing financial expertise to support Musk’s AI and social media ventures.

Anthony Armstrong, a former global head of tech mergers and acquisitions at Morgan Stanley, has been appointed Chief Financial Officer (CFO) of Elon Musk's artificial intelligence startup, xAI. According to the Financial Times, Armstrong will be in charge of the financial operations of xAI and Musk's social media network X, which was once Twitter. Mike Liberatore, the former CFO of xAI, is among the executives leaving Musk's companies in tandem with Armstrong's hiring. Liberatore reportedly resigned due to internal disagreements about the company's ambitious financial targets and organizational design.

Because he worked with Musk at the Department of Government Efficiency (DOGE) and advised him on a number of high-profile projects, Armstrong is a trusted member of Musk's inner circle. As Musk aims to speed the growth of xAI, he is a key actor due to his vast experience in tech funding and mergers.

A new round of funding is reportedly being negotiated by xAI, the most valuable AI Company in the world, with a potential valuation of $200 billion. XAI was launched in 2023 with the intention of competing with well-known AI behemoths by denouncing them for their draconian restrictions and insufficient security measures.

In addition to his work at xAI, Armstrong must stabilize X's finances after an exodus of advertisers as a result of Musk's loose content management regulations. As Musk's businesses go through this difficult time, his leadership will be essential.
