Jeff Bezos’s Project Prometheus poaches xAI co-founder from OpenAI in escalating AI talent battle

Jeff Bezos is quietly assembling something big—and he’s doing it by pulling talent straight out of the industry’s most influential AI labs.

His stealth venture, Project Prometheus, has hired Kyle Kosic, a co-founder of xAI and a former engineer at OpenAI, marking one of the clearest signals yet that Bezos is serious about competing at the highest level of AI infrastructure.

The move, first reported by the Financial Times, lands at a time when the fight for top AI talent has turned into a full-blown arms race.

Kosic isn’t just another hire. He was part of xAI’s earliest team, one of its first 11 employees, and helped build the infrastructure behind Colossus, the supercomputer powering Grok. His path through the AI ecosystem reads like a map of the industry’s power centers—OpenAI, then xAI, then back to OpenAI, and now into Bezos’s orbit.

“Bezos’s Project Prometheus poaches xAI co-founder from OpenAI. Kyle Kosic joins Project Prometheus, the secretive start-up working on systems that can understand the physical world,” The Financial Times reported.

At Project Prometheus, Kosic is expected to work on large-scale infrastructure, the kind that determines whether ambitious AI ideas actually make it into the real world.

His departure adds to a striking trend. Every original co-founder from xAI has now left the company, pointing to deeper shifts behind the scenes as priorities change and talent reshuffles across competing labs.

Inside Bezos’s AI play: Project Prometheus hires xAI co-founder to power industrial AI ambitions

Project Prometheus itself remains mostly out of public view, though what has surfaced paints a clear picture of its ambitions. Launched in late 2025, the company is led by Jeff Bezos alongside physicist Vikram “Vik” Bajaj, a former Google X leader known for pushing unconventional research programs.

The startup raised $6.2 billion at launch, making it one of the most heavily funded AI ventures at such an early stage. That level of capital signals long-term intent, not quick wins.

Prometheus isn’t chasing chatbots or coding assistants. Its focus is what insiders describe as AI that can “understand the physical world.” The goal is to build systems that interact with real industries—manufacturing, aerospace, automotive, architecture—using data drawn from physical processes rather than text alone.

Project Prometheus is only one piece of a much larger AI push by Bezos. Just last month, the Wall Street Journal reported that the Amazon founder was in early discussions to raise a staggering $100 billion for a new AI-focused fund aimed at acquiring manufacturing companies and pushing them toward automation.

That direction sets it apart from companies like OpenAI, Google, and Meta, where much of the progress has centered on language models.

Internally, the company is said to be exploring a structure similar to a “Berkshire Hathaway-type holding company,” backing or acquiring businesses across key sectors to gain access to real-world data. Partnerships with sovereign funds in regions like Singapore and the Gulf are reportedly part of that vision.

Even without a detailed product roadmap made public, Prometheus is already building a presence, with teams spread across San Francisco, London, and Zurich and a growing roster of hires drawn from leading AI labs.

Kosic’s arrival fits that pattern. It shows where Bezos is placing his bets: not on surface-level applications, but on the infrastructure layer that makes everything else possible.

The broader signal is hard to miss. AI talent is moving faster than ever between companies, and the lines between rivals are getting thinner. Engineers who helped build one generation of systems are now shaping the next somewhere else.

For Bezos, this is familiar territory. He built Amazon by investing early in infrastructure others overlooked. With Project Prometheus, he appears to be applying that same playbook to AI.

If the company can turn its vision into working systems, it could push AI deeper into the physical industries that still run much of the global economy.

For now, the hiring of Kyle Kosic offers a glimpse into what’s taking shape behind closed doors—and how serious the competition has become.
