Prometheus shares are not public exchange-traded shares. The physical-AI company co-led by Jeff Bezos and former Google X executive Vik Bajaj became public knowledge in November 2025 with $6.2 billion in initial funding, and on June 11, 2026 it announced a $12 billion Series B at a $41 billion valuation with money from Bezos, JPMorgan Chase, Goldman Sachs and BlackRock, as reported by TechCrunch, Axios and GeekWire. The company says it is building an artificial general engineer to automate the design and manufacturing of complex physical systems. No registration statement has appeared on SEC EDGAR as of the latest site review. Segmara does not publish an indicative mark for Prometheus and does not sell, broker, or arrange share purchases; any private transaction is subject to eligibility, availability, transfer approval, documentation, pricing and final terms.
Segmara is an independent research site. Segmara does not sell, broker, or arrange share purchases. Nothing here is investment advice.
A startup co-led by Jeff Bezos that raised $12 billion in one round at a $41 billion valuation is a rare event, and the company's stated goal of automating engineering for jet engines and drug compounds attracts both AI and industrial investors.
TechCrunch and Axios reported the June 11, 2026 round after Bloomberg had reported in April that it was tracking toward $10 billion at $38 billion, which shows how fast the private mark moved.
Prometheus is funded by its founders and a small set of large institutions; there is no company-run tender offer, no per-share price in the public record and, so far, no employee liquidity program that would create secondary supply.
Any secondary route depends on seller supply, company transfer approval, accredited-investor eligibility and platform minimums. Segmara carries no indicative mark for Prometheus because no dated per-share reference exists.
Segmara lists Prometheus with no indicative price yet. Segmara does not sell, broker, or arrange share purchases.
The answer stays conditional: access is subject to eligibility, availability, transfer approval, documentation and final terms, and Segmara does not sell or broker Prometheus shares.
Public round-by-round marks are incomplete for this company. Segmara shows the listing mark and keeps the seed-to-IPO analysis focused on verifiable funding, tender, or secondary signals.
