TLDR
- Tony Wu and Jimmy Ba have left Elon Musk’s xAI, reducing the original founding team from 12 to six members
- Ba’s departure followed reported internal conflicts over pressure to enhance AI model capabilities and compete with rivals
- The exits happened shortly after SpaceX announced plans to acquire xAI for $1.25 trillion with an IPO scheduled for 2026
- xAI has dealt with controversies including Grok chatbot issues and high operational costs while competing in the AI market
- The company was valued at over $200 billion in January 2026 but continues to face leadership turnover challenges
Elon Musk’s artificial intelligence venture xAI lost two more founding members this week. Tony Wu and Jimmy Ba announced their exits from the company on social media platform X. The departures reduce xAI’s original 12-person founding team to just six members.
Ba made his announcement on Tuesday evening, thanking Musk for the opportunity. Wu revealed his exit one day earlier. Neither co-founder provided specific reasons for their decisions or shared future plans in their posts.
The Financial Times reported that Ba’s resignation came after friction within xAI’s technical division. The tensions stemmed from pressure to boost the company’s AI model capabilities. Musk has been driving the team to match competitors like OpenAI and Anthropic.
Ba did not respond to requests for comment about the reported conflicts. The timing of both departures raises questions about the company’s internal dynamics.
Wave of Departures From Leadership
xAI has experienced steady attrition among its founding team over the past year. Kyle Kosic, Igor Babuschkin, and Greg Yang previously left the organization. The company now operates with half its original leadership group.
The startup launched in early 2023 under Musk’s direction. By January 2026, xAI reached a valuation exceeding $200 billion. The company developed Grok, an AI chatbot integrated into the X platform.
SpaceX Acquisition and IPO Plans
The co-founder resignations followed a major corporate announcement from SpaceX. Musk’s aerospace company revealed plans to purchase xAI in a deal creating a $1.25 trillion entity. SpaceX intends to take the combined company public in 2026.
The initial public offering would fund Musk’s vision of launching data centers into space. The acquisition represents a restructuring of Musk’s AI ambitions under his space technology umbrella.
Company Faces Multiple Challenges
xAI has encountered several obstacles in recent months. The Grok chatbot generated deepfake pornography on X earlier this year. This incident triggered multiple class-action lawsuits against the company.
Financial pressures have mounted as xAI spends heavily on development. The company is working to upgrade its technology to compete with established AI firms. OpenAI and Anthropic maintain strong positions in the market.
The technical team operates under intense pressure to deliver improvements. These demands reportedly contributed to the internal tensions. xAI continues investing in research and development to advance its products.
The artificial intelligence sector remains highly competitive with rapid innovation cycles. xAI must navigate talent retention issues while developing cutting-edge technology. The company competes for engineers and researchers in a tight labor market.
