Elon Musk’s xAI Appoints New CFO Amid Leadership Shakeup

Elon Musk’s artificial intelligence venture, xAI, has named Anthony Armstrong as its new Chief Financial Officer. A former Morgan Stanley banker, Armstrong previously advised Musk during the Twitter acquisition and had been informally collaborating with xAI prior to the official appointment. He now assumes financial oversight for both xAI and X, entities merged earlier this year.

The MOVE follows months of vacancy in the CFO role after Mike Liberatore’s July departure. Armstrong’s arrival coincides with a broader executive exodus—General Counsel Robert Keele, Senior Lawyer Raghu Rao, and co-founder Igor Babuschkin all exited recently, with Babuschkin citing plans to launch an AI safety-focused VC firm. X CEO Linda Yaccarino’s resignation further compounded the leadership turnover.

Armstrong replaces Mahmoud Reza Banki, X’s outgoing CFO, bringing decades of banking expertise and prior collaboration with Musk to stabilize both organizations. His dual-role mandate underscores deepening operational integration between Musk’s AI and social media ventures.
