Elon Musk revealed that xAI, his artificial intelligence startup, is undergoing a foundational rebuild following a series of co-founder departures and a recent merger with SpaceX valued at $1.25 trillion [1]. Musk acknowledged on X that xAI 'was not built right first time around, so is being rebuilt from the foundations up,' after co-founders Zihang Dai and Guodong Zhang left the company this week, joining Jimmy Ba, Tony Wu, and Toby Pohlen, who exited in the past month [1]. This exodus leaves Musk with only two original co-founders from 2023 [1].
The merger between SpaceX and xAI last month valued SpaceX at $1 trillion and xAI at $250 billion, according to documents viewed by CNBC [1]. Tesla, Musk's automaker, agreed to invest $2 billion into xAI, tied to a previously announced $20 billion funding round [1]. SpaceX is preparing for a public offering later this year, which is expected to be a record IPO if it proceeds [1].
SpaceX recently hired two programmers from AI coding startup Cursor, Andrew Milich and Jason Ginsberg, as Musk reportedly ordered job cuts in response to the rapid success of generative AI rivals OpenAI and Anthropic [1]. Musk apologized on X for declining offers or interviews to many talented candidates at xAI and stated that he and Baris Akis are reviewing company interview history to reach out to promising candidates [1].
xAI is also facing controversies related to its chatbot and image generator Grok, which is under government investigation in multiple international jurisdictions for enabling users to generate non-consensual sexual images, including deepfake porn [1]. Despite these challenges, Grok has secured government contracts from the Defense Department and General Services Administration under the Trump presidency [1]. xAI has been investing billions in power and data infrastructure around Memphis, Tennessee [1].
CONCLUSION
Elon Musk's xAI is undergoing a major restructuring amid significant co-founder departures and operational challenges, including controversies surrounding its AI products. The merger with SpaceX and upcoming IPO, alongside substantial investments from Tesla, signal high market impact and investor interest. However, talent retention and regulatory scrutiny remain key risks for xAI's future trajectory.
