xAI, Elon Musk’s AI company, has appointed Anthony Armstrong as its new Chief Financial Officer, according to the Financial Times.

The leadership appointment comes as xAI positions itself in the competitive artificial general intelligence landscape. In August 2025, Musk indicated via his official X account that xAI had “all the pieces” nearly in place to achieve artificial general intelligence.

xAI acquired the social platform X in an all-stock transaction in March 2025, integrating it into operations to enhance AI model training and data center development. The company is also developing Grokipedia, which Musk described in September 2025 as a major improvement over existing encyclopedias, aimed at advancing xAI’s goal of understanding the universe through AI.

The CFO appointment reflects xAI’s expansion phase as it builds advanced AI infrastructure and pursues strategic acquisitions. Armstrong will lead financial oversight for Musk’s AI venture and social platform X.
