Elon Musk’s artificial intelligence venture, xAI, is undergoing a sweeping reorganization of its engineering team as it integrates more deeply with SpaceX. This structural overhaul comes at a critical juncture for the company, which is navigating a period of leadership volatility and technical challenges while preparing for a highly anticipated initial public offering (IPO) for SpaceX.
The reorganization follows a massive merger in February 2026, where SpaceX acquired xAI in a deal that valued the combined entity at $1.25 trillion ([1]). The transaction, described as the largest merger of all time, valued SpaceX at $1 trillion and xAI at $250 billion ([1]). Musk has framed the combination as the creation of a “vertically-integrated innovation engine” aimed at blending AI, rocket technology and space-based internet ([2]).
However, internal documents suggest that the path to integration has been turbulent. The xAI engineering reorganization is designed to address perceived gaps in competitiveness and technical performance as the company races to keep pace with rivals such as OpenAI, Google, and Anthropic.

New Leadership and Technical Priorities
As part of the restructuring, Michael Nicholls, the senior vice president of Starlink at SpaceX, has reportedly assumed the role of xAI president. In an internal memo, Nicholls stated that the company is “clearly behind” its competition and is taking immediate action to close the gap.
The reorganization specifically targets the AI development lifecycle, dividing responsibilities among new leads to streamline the creation of the Grok models. According to internal reports, the new structure includes:
- Pre-training: Led by Devendra Chaplot, a former researcher at Facebook and Thinking Machines Labs, focusing on the initial phase where models learn general patterns from massive datasets.
- Model Factory and Tooling: Overseen by Aman Madaan, who will manage the infrastructure, data pipelines, and training workflows.
- Post-training and Reinforcement Learning: Headed by Aditya Gupta, focusing on fine-tuning and optimizing models for real-world chat and coding applications.
- Specialized Training: Beibin Li (formerly of Microsoft and Meta) will lead post-training for Grok Code, while Xuhui Jia (formerly of Google DeepMind) and Yukun Zhu will lead video and image training.
The product side of the house is also seeing a shift. Andrew Milich and Jason Ginsburg, who joined from the AI coding company Cursor in March, will lead the product team overseeing Grok Main, Grok Voice, and Grok Imagine.
Addressing Infrastructure Weaknesses
A significant portion of the reorganization focuses on the physical and compute layers of the AI operation. Here’s a strategic priority for Musk, who has proposed the development of “orbital data centers” to solve the energy constraints of terrestrial AI computing ([2]).
Despite these ambitions, the current state of xAI’s compute performance has reportedly been a point of contention. In the internal memo, Nicholls described the training performance of xAI’s compute as “embarrassingly low,” noting that the company intends to implement significant improvements within the next two months.
To address these deficits, SpaceX leadership has been embedded into xAI’s operations. Daniel Dueri, the director of software engineering at SpaceX, will lead compute infrastructure, while Jake Palmer will oversee physical infrastructure. Matt Monson, the director of Starlink software at SpaceX, has taken on a leadership role in data at xAI.
Cofounder Exodus and the ‘Tesla Playbook’
The current reorganization follows a period of significant instability within xAI’s founding team. Since January, eight engineers who helped found the company alongside Musk have departed. This exodus includes several high-profile cofounders: Ross Nordeen, Guodong Zhang, Manuel Kroiss (who led Grok Code), and Toby Pohlen (who helped lead the Macrohard computer-use agent project).
This loss of early leadership has left the company’s organizational structure in a state of flux. Reports indicate that Musk has at times managed dozens of direct reports personally, while engineers from Tesla and SpaceX have been deployed to xAI’s Palo Alto office to assist with the transition.
Musk has acknowledged the early failings of the company’s structure, stating on X in March that “xAI was not built right first time around, so is being rebuilt from the foundations up.” This approach mirrors what some describe as the “Tesla playbook,” where the company undergoes aggressive restructuring and foundational rebuilds to accelerate innovation during scaling phases.
The instability has also extended to the broader workforce. Since February, xAI has reportedly shed dozens of employees, including cuts to teams working on the Grok Imagine video and image generation tool, the Macrohard AI agent project, and the recruiting team.
Strategic Implications for the SpaceX IPO
The urgency of the xAI engineering reorganization is tied directly to the financial roadmap of its parent company. SpaceX is expected to file for an initial public offering later in 2026 ([1]). The merger with xAI was structured as a share exchange, converting one share of xAI into 0.1433 shares of SpaceX stock ([1]).
By integrating xAI, SpaceX is not merely acquiring an AI startup but is attempting to build a vertically integrated ecosystem. The goal is to leverage SpaceX’s launch capabilities and Starlink’s connectivity to power AI compute in space, bypassing the electricity limitations of Earth-based grids ([2]). If successful, this synergy could significantly bolster SpaceX’s valuation ahead of its public debut, with some projections suggesting a potential valuation of over $2 trillion.
Key Takeaways: The xAI Restructuring
- Leadership Shift: Michael Nicholls (SpaceX SVP of Starlink) is now xAI president, tasked with catching up to AI competitors.
- Technical Overhaul: New leadership roles established for pre-training, post-training, and product development to refine Grok models.
- Infrastructure Focus: A push to fix “embarrassingly low” compute performance, utilizing SpaceX software engineering expertise.
- Talent Volatility: Eight cofounders have left since January, accompanied by dozens of layoffs in recruiting and specialized AI projects.
- IPO Pressure: The restructuring is a precursor to the SpaceX IPO planned for later in 2026, with a combined entity value of $1.25 trillion ([1]).
The next major milestone for the combined entity will be the formal filing of the SpaceX IPO, which is expected later this year. This filing will provide more definitive data on the company’s financial health and the actual realized value of the xAI integration.
