Jeff Bezos' New AI Venture Prometheus Raises $12B, Valuation Reaches $41B

Jeff Bezos' new AI venture Prometheus has raised $12B in fresh funding, pushing its valuation to about $41B. Meanwhile, OpenAI confidentially filed for an IPO with the SEC, setting up a potential race with Anthropic as both companies seek massive new capital.This week's private company news:OpenAI announced that it will acquire Ona, "bringing its secure cloud execution and orchestration technology into our rapidly expanding Codex ecosystem." OpenAI said: "As Codex becomes more capable, its most valuable work is unfolding over hours or days, rather than minutes. We believe people should be able to delegate more ambitious work without remaining tied to the machine where it began. The work should continue beyond the initial session, with Codex making it possible to stay connected and check progress, provide direction, make decisions, and review results from anywhere. Ona will help us do that. Its technology provides secure, persistent environments where agents can access the tools, systems, and context they need to make progress over time."Sam Altman, CEO of Microsoft-backed OpenAI, and the Trump administration are in ongoing discussions over a possible government stake in the ChatGPT maker, CNBC's Ashley Capoot and Kate Rooney. The talks have been in progress for over a year, as Altman first shared the idea with the White House last year, the authors say, citing a source familiar with the matter. Such discussions continued this week as the CEO met with a number of lawmakers and officials in Washington, D.C. to go over regulation and the latest developments in AI, the authors note. As part of a potential pact, OpenAI could donate equity to the U.S. government to seed something in the vein of a "Public Wealth Fund" that the ChatGPT maker outlined in its April policy proposal, the authors say.Some of the biggest capital raises by private companies this week include:Prometheus- Jeff Bezos' newest AI venture has secured a massive $12B funding round.
