Prometheus, the AI physical startup co-founded late 2025 by Jeff Bezos and Vik Bajaj, announced on June 11, 2026, a second round of $12 billion at a valuation of $41 billion, according to TechCrunch. The syndicate includes Bezos personally, JPMorgan Chase, Goldman Sachs, BlackRock, as well as DST Global and Arch Venture Partners.
The remarkable fact is not the amount: it's the simultaneous presence of three major banking and asset management names in a capital syndicate tied to a 150-person company that has, to date, disclosed no products. TechCrunch describes these investors as "among others" - the phrasing does not indicate a lead («lead»). For an AI funding decision-maker, the event is less a raise than a shift in the perimeter of investors in a late-stage round.
Two rounds in less than six months, unspecified instrument
The second round fits into a rapid pace. According to CNBC, Prometheus's first round, launched at the end of 2025, was worth $6.2 billion; the round announced on June 11, 2026, adds $12 billion. A few days ago, the Financial Times, reported by Implicator.ai, wrote that JPMorgan and BlackRock were anchoring a current round of $10 billion at a $38 billion valuation - the round that was actually closed is higher in both dimensions.
The exact structure of the instrument has not been disclosed. TechCrunch notes that the funds come from Bezos and the three major institutional investors, among other subscribers, without specifying whether it is classic equity, a structured note, or a convertible. The distinction is not cosmetic for a decision-maker: an equity pre-revenue at $41 billion and a convertible note at the same valuation do not involve the same risk or the same seniority.
Regarding the use of funds, Bezos stated that a large portion of the capital will be allocated to computing needs - in other words, the productive infrastructure remains to be built. ActuIA's estimate, by dividing the $41 billion by the 150 employees, gives a valuation per employee of approximately $273 million. The number is not a market price but an indicator of the capital density attached to an initial workforce.
An extraordinary valuation for physical AI
Three comparable deals help place the round. Physical Intelligence (Pi), often cited as a direct competitor in applied AI to robots, has a confirmed valuation much lower; OpenAI, a comparable large-scale software company, operates at another stage of capital.
| Actor | Valuation | Amount raised (last round) | Date | Source |
|---|---|---|---|---|
| Prometheus | 41 Md$ | 12 Md$ | June 2026 | TechCrunch |
| Physical Intelligence | 5,6 Md$ (confirmed) | 600 M$ (Series B) | November 2025 | Bloomberg via Teahose |
| OpenAI | 852 Md$ (post-money) | 122 Md$ | March 2026 | openai.com |
On the strict sense of physical AI, the gap is in multiples. According to Bloomberg, via Teahose, Pi closed its Series B of 600 million dollars at a valuation of 5.6 billion in November 2025, which is about seven times less than Prometheus' valuation. ActuIA estimates this contrast as about 10x in valuation per employee: 273 million for Prometheus (41 Md$ for 150 people), versus about 28 million for Pi (5.6 Md$ for about 200 people). The gap does not mean that Pi is undervalued or Prometheus overvalued - it means that investors are paying here a premium for a signatory (Bezos) and an institutional syndicate, not for product indicators.
The shift in the subscriber perimeter
The recent precedent illuminates what has changed. ActuIA documented in its magazine No. 18 that OpenAI had established a $4 billion credit facility with several major banks in October 2024 - a debt instrument, without equity participation. According to the official Blackstone statement from May 4, 2026, Anthropic, Blackstone, Hellman & Friedman, and Goldman Sachs have also formed a joint venture capitalized at $1.5 billion to deploy Claude in enterprise, with Goldman contributing $150 million: this time it is equity, but on a deployment vehicle, not on the balance sheet of a laboratory.
The Prometheus round, if its instrument is confirmed as equity participation, would mark a further step - direct institutional investment in a pre-revenue laboratory, without an intermediate vehicle. The conditional is mandatory: neither TechCrunch nor specialized sources specify the structure. DST Global and Arch Venture Partners, classic venture capital managers, remain in the syndicate, which suggests that the nature of the round is not exclusively institutional.
Two variables will shape the next steps. Bezos holds co-direction of Prometheus and the executive presidency of Amazon, which, according to publicly available data, is simultaneously pursuing an accelerated automation plan under Andy Jassy: the arbitrage of his time and public statements will become an observation point. The short timeline, on the other hand, depends on a product demonstration: Prometheus has not disclosed any roadmap or verifiable milestone. The question that will decide is not about the capital raised, but about what will appear in a public demonstration before the next round.
