Elon Musk appointed a new Chief Financial Officer (CFO) for his AI company xAI on October 7, 2025: Anthony Armstrong, a former banker from Morgan Stanley. According to Reuters and the FT, a key feature of this appointment is that Armstrong will be responsible for the finances of both xAI and the social media network X simultaneously. This move formalizes and strengthens the deep operational and financial integration between the two companies. Armstrong, who became a confidant of Musk after advising him on the Twitter acquisition, replaces the previous CFO who left due to disagreements. The appointment of an experienced Wall Street professional is intended to strengthen financial management at xAI amid plans to raise billions in investment and to stabilize the financial situation at the X platform, which has faced an advertiser exodus.
