# xAI Founding Team Now Half Gone After Exits
In a stunning development for Elon Musk's ambitious AI startup, half of xAI's founding team—six out of the original 12 co-founders—has now departed the company, with recent back-to-back exits intensifying concerns over talent retention amid an upcoming IPO and SpaceX merger[1][2][4]. The wave of departures, including key figures like Yuhuai (Tony) Wu and Jimmy Ba this week, signals potential turbulence at the heart of Musk's push to rival OpenAI and other AI giants[3][4].
Key Departures Rock xAI's Core Leadership
The exodus gained momentum this week when Yuhuai (Tony) Wu, who led xAI's reasoning team, announced his resignation on Monday night via a post on X, stating, "It's time for my next chapter. It is an era with full possibilities: a small team armed with AIs can move mountains and redefine what's possible."[1][2][4]. Less than 24 hours later, Jimmy Ba, another co-founder overseeing research, safety, and enterprise efforts who reported directly to Musk, confirmed his exit, thanking Musk and pledging to "continue to stay close as a friend of the team."[1][3][4].
These moves follow a pattern: five of the six co-founder departures occurred in the past year alone. Earlier exits include infrastructure lead Kyle Kosic, who joined OpenAI in mid-2024; Google veteran Christian Szegedy in February 2025; Igor Babuschkin, who left in August 2025 to start a venture firm; and Greg Yang last month, citing health issues[1][3][4]. Beyond co-founders, at least six to eleven other engineers and researchers, such as Ayush Jaiswal, Simon Zhai, and Hang Gao, have publicly announced their departures in recent days or weeks, thinning xAI's technical ranks[2][3][5].
Internal Pressures and Project Shortfalls Fuel Turnover
Staff frustrations appear to stem from leadership overpromising on technical milestones to Musk, creating intense pressure, according to sources familiar with the matter[1]. xAI's coding project, dubbed MacroHard and aimed at competing with OpenAI's Codex and Anthropic's Claude Code, has reportedly underperformed, while the AI companions product—including an anime character named Ani capable of erotic conversations—missed engagement targets[1].
Musk held an employee call on Tuesday to address technical leadership changes, amid complaints of unrealistic expectations[1]. High turnover is common in AI, but the scale at xAI stands out, with some departing staff hinting at desires for more autonomy in smaller teams to accelerate frontier AI development[2][4]. Neither xAI nor Musk has publicly commented on the exits[2][3].
Strategic Challenges Amid SpaceX Merger and IPO Push
The timing exacerbates risks for xAI, now fully merged with SpaceX and eyeing a blockbuster IPO in the coming months[1][3][4][6]. With C-suite losses over the past year—including general counsel, CFO, and head of product engineering—plus the earlier exit of X's CEO Linda Yaccarino in July 2025, the company faces a talent crunch at a pivotal moment[3].
Observers note that while splits seem amicable and windfalls from the merger could spur new ventures, retaining top AI talent is critical as stakes rise[4][5]. Three departing staff mentioned starting new projects with ex-colleagues, underscoring a competitive landscape where researchers seek independence[2].
