Who is Anthony Armstrong? New Chief Financial Officer of Elon Musk’s Rs 10025418432300 xAI Group

Elon Musk has appointed Anthony Armstrong, a former Morgan Stanley executive, as the new Chief Financial Officer (CFO) of his artificial intelligence company xAI. The appointment strengthens Musk’s control over his combined USD 113 billion xAI and X group, according to a report by the Financial Times.

Armstrong previously worked with Musk during the USD 44 billion acquisition of X (formerly Twitter) and has since become one of the billionaire’s most trusted advisors. As CFO, Armstrong will now handle the financial operations of both xAI and X (Twitter), marking a major step in his growing role within Musk’s business empire.

Who is Anthony Armstrong?

Anthony Armstrong is a seasoned finance expert who built his career at Morgan Stanley, where he specialized in technology mergers and acquisitions. He played a vital role in structuring Musk’s Twitter takeover deal in 2022. His sharp financial skills and strategic thinking have earned him a reputation as one of the most reliable minds in corporate finance.

Before joining xAI officially, Armstrong had already been working with the company for several weeks. His X profile now displays the xAI logo, confirming his new position.

Anthony Armstrong’s Wife and Personal Life

Anthony Armstrong is known to keep his personal life private, but sources close to him describe him as a devoted family man. He is married to Sarah Armstrong, who works in the corporate finance sector as well. The couple is known for maintaining a low profile despite Armstrong’s growing prominence in Silicon Valley circles. They are often seen attending private business events together, balancing their professional and family lives discreetly.

A Strategic Move for Musk

Armstrong’s appointment comes during a period of big leadership changes across Musk’s companies. Linda Yaccarino, former CEO of X, and Mike Liberatore, ex-CFO of xAI, both recently stepped down. Armstrong now replaces Liberatore, who joined OpenAI after just three months due to reported differences over company structure and goals.

Challenges Ahead

One of Armstrong’s key challenges will be restoring financial stability to X, which has seen falling ad revenue since Musk relaxed content moderation rules, prompting several major brands to withdraw advertising.

With his deep experience from Morgan Stanley and a strong understanding of Musk’s vision, Armstrong is expected to help streamline the financial systems across the growing Musk empire. He will also take over responsibilities from Mahmoud Rezam Banki, X’s outgoing CFO.

Armstrong’s rise—from advising Musk during the Twitter deal to now managing finances for both X and xAI—shows how Musk is aligning his companies under a trusted and tightly connected executive team.
