Seven months after announcing his return to the executive team and founding the AI startup Prometheus, Jeff Bezos rarely talks about how it feels to sit back in the CEO position again.

In a recent CNBC interview, Bezos admitted that he originally had no plans to be CEO again.

After stepping down as Amazon's CEO in 2021, Bezos handed over daily management to Andy Jassy, playing more of a founder, chairman, and investor role himself.

He still stands behind Amazon, Blue Origin, and The Washington Post, just no longer managing a company's daily operations as CEO.

But for Prometheus, he returned to the front lines, resuming the life of a startup founder. Bezos describes this state as “Type 2 fun”—the process is exhausting, but looking back, it’s all worth it.

Prometheus was founded less than a year ago, with about 150 employees, but its valuation has already reached an astonishing $41 billion.

This is Bezos’s first personal foray into a new future since leaving Amazon.

And yet, this future still cannot escape his old rival, Elon Musk.

Prometheus

In Greek mythology, Prometheus is the Titan who brought fire to humanity. He is associated not only with “fire” but is also often interpreted as a symbol of craftsmanship, creation, civilization, and foresight.

On June 11, Axios reported that Prometheus completed a $12 billion Series B funding round, with the company's valuation reaching $41 billion. The investor lineup nearly covers Wall Street and top global venture capital firms, including JPMorgan Chase, BlackRock, Goldman Sachs, internet investment giant DST Global, and life sciences and hard tech investor Arch Venture Partners. Bezos himself continues to participate in the investment.

Last November, when the company launched, it raised $6.2 billion in Series A; just seven months later, it completed a $12 billion Series B, nearly doubling the amount in a single round, with total funding exceeding $18 billion.

In other words, as soon as it went public, it stood at the top of the valuation pyramid for physical-world AI.

Figure AI, which makes humanoid robots, announced in September 2025 that it had raised over $1 billion in Series C funding, with a post-money valuation of $39 billion;

Skild AI, which develops “AI brains” for robots, announced in January this year that it raised $1.4 billion in Series C, with a valuation exceeding $14 billion;

Another general intelligence robotics company, Physical Intelligence, has been confirmed at a valuation of $5.6 billion, and reports suggest a new funding round could push its valuation over $11 billion.

But less than a year after its founding, Prometheus’s valuation already surpasses these star companies in embodied intelligence.

According to Bezos, Prometheus is not building robots but rather a kind of Artificial General Engineer AI.

Simply put, Prometheus aims to enable AI to participate in the design, simulation, testing, and manufacturing of complex real-world products.

Jet engines, spacecraft, chips, cars, medical devices, pharmaceuticals, consumer electronics, robots… the R&D cycles for these products often span years. A design must be repeatedly simulated, prototyped, tested, failed, and revised, then start over.

Prometheus seeks to compress this process—it’s not just about accelerating a single task but the entire “invention cycle”: from design to simulation, testing to manufacturing, and back to the next design iteration.

More importantly, industrial AI remains a largely unexplored frontier, a blue ocean full of future potential.

This field isn’t without players—robotics companies are working on embodied intelligence, engineering software firms on simulation and design optimization, NVIDIA on physical AI platforms, and manufacturing giants are integrating AI into their production processes.

But no truly flagship product has yet emerged.

This relates to the complexity of industrial AI itself: it deals not with text and code on screens but with materials, structures, temperatures, energy consumption, costs, supply chains, and safety redundancies in the real world.

Here, AI cannot just produce seemingly reasonable answers.

It must withstand simulation, pass testing, and ultimately be manufacturable in reality.

Prometheus’s $41 billion valuation isn’t for an already proven mature company. It’s for a potential that’s enormous once realized, even if unproven now.

Prometheus stole fire, giving humans a tool to change the world.

Bezos’s Prometheus aims to hand this fire—AI—to engineers in the real world.

Bezos’s Third Major Return

Excluding asset investments like acquiring The Washington Post, Prometheus is Bezos’s third truly personal return to the front lines.

The first was Amazon.

In 1994, he left Wall Street and founded Amazon in Seattle. It started as an online bookstore. Later, it grew into one of the world’s largest e-commerce platforms. By 2024, Amazon’s annual revenue exceeded $630 billion; its AWS division has become one of the most important players in global cloud computing.

Bezos built a supporting infrastructure for modern commerce: warehousing, logistics, cloud computing, advertising, membership systems, and the operational machinery around these systems.

The second was Blue Origin.

Founded in 2000, Blue Origin deals with the physical world. Unlike Amazon’s digital realm, here there’s no “rapid trial and error”—only repeated design, manufacturing, testing, and launching.

Blue Origin isn’t just a paper space dream. The New Shepard has completed multiple suborbital flights and taken tourists to space; the BE-4 engine is the main engine for ULA’s new Vulcan rocket; New Glenn is Blue Origin’s core product entering the heavy orbital launch market.

Rockets aren’t software—they must ignite, test, and launch in the physical world, subject to physical stability and manufacturing precision.

Amazon gave Bezos experience in building “platforms for complex systems,” Blue Origin gave him experience in “complex engineering in the physical world.” With Prometheus, these two come together.

In the CNBC interview, Bezos mentioned that he initially was just an investor, but after seeing the project’s progress, he realized he “couldn’t sit on the sidelines,” and thus took on the role of co-CEO himself.

Because Prometheus isn’t a lightweight application suited for remote investment. It’s a complex system aimed at the real industrial world. It requires AI capabilities, engineering understanding, modeling expertise, manufacturing knowledge, software speed, and respect for physical constraints.

This intersection aligns perfectly with Bezos’s three decades of experience.

Prometheus combines Amazon-like platform ambitions with Blue Origin-like engineering challenges. Bezos’s return to CEO isn’t just about spotting a new AI trend; it’s about solving a familiar problem with a new approach.

And this time, he’s not alone.

Another co-CEO of Prometheus, Vik Bajaj, was an early core figure in Google’s life sciences division, involved in founding Google Life Sciences, later known as Verily; he also served as Chief Scientific Officer at Grail, a cancer early detection company.

In other words, Bajaj’s work has always been at the intersection of science, engineering, data, and real-world industry.

This co-CEO duo is intriguing: Bezos brings Amazon’s platform strength and Blue Origin’s engineering experience; Bajaj brings expertise in life sciences, hard tech, and complex R&D systems.

One understands how to scale complex systems into large platforms; the other knows how to push scientific problems into real industries.

In the CNBC interview, Bezos said that currently, Prometheus takes up most of his time, followed by Blue Origin and AI-related work within Amazon.

In a sense, this is somewhat unusual—over the past year, many prominent CEOs have chosen to step back behind the scenes, citing the AI era as a reason for needing a different leader to guide transformation.

But Bezos is heading in the opposite direction, not managing Amazon’s mature giant but dedicating his most time to a less than a year old AI startup.

For a 61-year-old billionaire to return to the office, there must be a compelling reason—perhaps he already sees that the next big opportunity to change the world is right there.

From “Blue Sky” to “Blue Ocean”

Blue Origin still exists. But it’s clear that the “blue sky” of commercial space has been largely taken over by SpaceX.

Last week, SpaceX completed its IPO, raising an initial $75 billion. After underwriters exercised their over-allotment option, the total raised reached $85.7 billion, making it the largest IPO in history. On its first day, SpaceX’s stock rose about 19%, with a market cap surpassing $2 trillion, and Musk was crowned the world’s first trillionaire.

SpaceX has taken not only the launch market but also the most glamorous stories of commercial space: reusable rockets, satellite internet, Mars ambitions, huge valuations, employee wealth, and an IPO that could rewrite capital market records.

In comparison, Blue Origin’s achievements—New Shepard, BE-4, and New Glenn—are not yet enough to change the game. The defining power in commercial space has shifted into SpaceX’s hands.

Moreover, Blue Origin recently faced a harsh reminder from the physical world.

On May 28, during a static fire test of the New Glenn rocket’s engine at Cape Canaveral, an explosion occurred, damaging the launch pad and possibly delaying future launches by months.

Space is brutal—no matter how much money, patience, or vision the company has, even with Bezos at the helm, rockets won’t fly on schedule just because of those factors.

According to a recent Reuters report on June 16, SpaceX’s stock price continued to rise, closing at $201.80, with a valuation of about $2.655 trillion, surpassing Amazon and briefly overtaking Microsoft. This means Musk not only won the definition of the space launch market but also managed to outpace Bezos’s Amazon in the capital markets.

This gives Bezos a sense of “being pushed from all sides, so why not carve out a new path.”

Unfortunately, Musk’s “omnipresence”—from space to ground, from cars to AI—means that even switching fields, he’s still playing against the same old rival, opening new chapters in the same game.

Tesla’s autonomous driving, humanoid robot Optimus, SpaceX’s highly engineered rockets, and xAI’s attempt to integrate models into Musk’s companies—all point to Musk’s AI strategy from the start: not just on screens, but aiming to bring AI into cars, robots, factories, and rockets, ultimately taking over more physical labor in the real world.

But there’s a fundamental difference: if Musk bets on “AI executing tasks in the physical world,” Bezos bets on “AI participating in real-world invention.”

The industrial AI track isn’t short of players—OpenAI is enhancing robot capabilities, Anthropic is entering industrial scenarios, NVIDIA is building a Physical AI foundation, and manufacturing giants are integrating AI into their processes. It’s a fierce competition, but who will become the gateway to industrial AI remains uncertain.

Prometheus aims to seize this position. It doesn’t see industrial AI as just a business line but as the core mission of the entire company. It seeks to dominate the human engineering in the AI era.

This time, Bezos doesn’t want to follow Musk.
