xAI (X) Co-Founder Leaves Amid Regulatory Scrutiny and M&A Pressure

Co-founder Tony Wu, a principal architect of xAI (X), has resigned amid regulatory investigations and consumer backlash, marking the fifth co-founder departure in the company’s turbulent strategic transition. Wu cited new opportunities on X, stating the move is the start of a “next chapter.” Other departing or stepping back founders include Igor Babuschkin, Kyle Kosic, Christian Szegedy, and Greg Yang, who is focusing on Lyme disease research. xAI, founded by Elon Musk in 2023 with 11 co-founders, is at the center of controversy over Grok’s deepfake generation, allegations of unauthorized explicit content and using real and minor likeness. Separately, SpaceX has acquired xAI, with SpaceX valued at about $10B and xAI at $25B, according to disclosed documents, signaling momentum toward a potential large IPO. Prior to this, Musk announced integrating xAI with X to leverage data, models, and compute resources. Analysts warn the pending restructuring and regulatory pressure may keep the company’s organizational and strategic outlook uncertain in the near term.
