Jeff Bezos launches Prometheus, a $41 billion（約6.6兆円） AI startup backed by $12 billion（約1.9兆円） in funding, aiming to build artificial engineers that accelerate physical manufacturing.

What happened: Jeff Bezos is leading Prometheus, an AI startup that emerged from stealth on Thursday, backed by $12 billion（約1.9兆円） in funding from Bezos personally, JPMorgan, BlackRock, Goldman Sachs, DST Global, and Arch Venture Partners. The company is valued at $41 billion（約6.6兆円）.

Why it matters: Prometheus aims to apply artificial intelligence to engineering and manufacturing at scale—treating physical-world problems the way large language models transformed text. Bezos described the goal as reducing tasks that currently take 100 engineers ten years down to ten engineers one year, fundamentally changing how much can be built.

What to watch: This is Bezos's first CEO role since stepping back from Amazon in 2021, signaling a major personal commitment to the venture. The company's success will determine whether AI can meaningfully accelerate real-world construction, from skyscrapers to semiconductors to jet engines.
