The final original co-founder of Elon Musk's AI venture, xAI, has reportedly departed, marking a complete reset for the company.
This isn't a sudden collapse but a deliberate, top-down overhaul. Elon Musk himself recently admitted that xAI "wasn't built right the first time around" and that he is rebuilding it "from the foundations up." The departure of all 11 original co-founders solidifies Musk's total control as he integrates the company into SpaceX, aiming for a potential IPO as early as mid-2026. This transition, however, comes with significant execution risk as the company must now rapidly hire new talent.
So, what led to this dramatic clean slate? The causal chain began with a major strategic shift.
First, the acquisition of xAI by SpaceX in February 2026 was the key catalyst. This merger brought xAI's research-oriented culture under SpaceX's famously intense, milestone-driven discipline. The pressure to prepare for an IPO heightened scrutiny and likely accelerated the exit of founders who were more focused on exploration than immediate product delivery.
Second, critical projects began to falter. The company's ambitious coding assistant, codenamed "Macrohard," reportedly stalled, leading to layoffs and project cuts. This product failure gave Musk a clear reason to declare the original structure a failure and justify a complete leadership change. The departures shifted from being seen as a "brain drain" to a necessary step for a new direction.
Finally, with the human capital in flux, Musk pivoted xAI's strategy to focus on what he can control: massive infrastructure. He unveiled plans for a "Terafab" and expanded the "Colossus 2" compute cluster in Memphis. This reframes the AI challenge as a hardware and systems integration problem—a domain where SpaceX and Tesla excel. By betting on overwhelming computational power, Musk aims to close the gap with competitors like OpenAI and Anthropic, even as he rebuilds the team from scratch.
