Two co-founders of Elon Musk’s artificial intelligence startup xAI have resigned in quick succession this week, deepening a churn at the firm as it grapples with competition, regulatory scrutiny and major strategic decisions ahead of a potential public listing.
The exits by Tony Wu and Jimmy Ba in the span of 48 hours mark the latest departures from a core founding team that has now shrunk by roughly half since xAI was established in 2023. The duo confirmed their resignations on social media, expressing gratitude for their time at the company but indicating a shift in focus to new opportunities.
Jimmy Ba, a co-founder of xAI, said Tuesday that it was his final day at the startup. His departure came less than 24 hours after fellow co-founder Tony Wu announced his resignation, bringing the number of founding members who have left to six out of the original 12.
“Last day at xAI,” Ba said on X. “xAI’s mission is to push humanity up the Kardashev tech tree. Grateful to have helped cofound at the start. And enormous thanks to @elonmusk for bringing us together on this incredible journey.”
He added, “We are heading to an age of 100x productivity with the right tools. Recursive self improvement loops likely go live in the next 12mo. It’s time to recalibrate my gradient on the big picture. 2026 is gonna be insane and likely the busiest (and most consequential) year for the future of our species.”
Wu struck a similar tone in his own post. “It’s time for my next chapter,” he wrote. “It is an era with full possibilities: a small team armed with AIs can move mountains and redefine what’s possible.”
Other early team members, including Igor Babuschkin, Kyle Kosic and Christian Szegedy, have also departed. Greg Yang said last month that he would step back from his role to focus on his battle with Lyme disease.
Leadership churn at xAI comes as the company navigates a series of external and internal pressures. The firm’s generative AI products, including its Grok chatbot and image generator, have attracted regulatory attention in multiple jurisdictions following incidents of harmful content generation and allegations of abusive outputs, particularly involving non-consensual image manipulation. European safety regulators have opened inquiries into the platform’s compliance with online safety laws.
At the same time, corporate developments have accelerated in recent months. Musk merged xAI with his social media platform X last year in a multibillion dollar transaction. Last week, he said SpaceX acquired xAI ahead of a potential public offering. According to documents viewed by CNBC, the deal values SpaceX at $1 trillion and xAI at $250 billion, making it the largest merger on record. A SpaceX IPO could reportedly target a valuation of $1.5 trillion as soon as this summer.
Musk launched xAI in 2023 with a group of engineers and researchers, positioning it as a competitor to OpenAI and Google. At the time, the company described its goal as seeking to understand the “true nature of the universe.”
On Tuesday night, Musk convened xAI employees for an all hands meeting focused on the company’s future ambitions. According to The New York Times, Musk told staff that xAI would need a manufacturing facility on the moon to build AI satellites and launch them into space using a giant catapult.
“You have to go to the moon,” he said, as reported by the Times. He added that such a move would allow xAI to secure more computing power than competitors. “It’s difficult to imagine what an intelligence of that scale would think about,” he said, “but it’s going to be incredibly exciting to see it happen.”
Musk acknowledged the pace of change inside the company. “If you’re moving faster than anyone else in any given technology arena, you will be the leader,” he told employees, according to the Times. “xAI is moving faster than any other company, no one’s even close.” He also noted that rapid growth can shift internal dynamics. “When this happens, there’s some people who are better suited for the early stages of a company and less suited for the later stages.”
It is unclear what prompted the timing of the all hands meeting. However, the back to back departures of two co-founders underscore a period of transition at a company that is expanding quickly, navigating regulatory challenges and preparing for what could be one of the largest public offerings in market history.
