Similar to @dominic's question, but with a greater value and a longer time horizon.

Doesn't have to be a single round, a cumulative amount would also count as long as it's associated with a single entity.

From their question (change the amount to 5 trillion and the timeframe to the end of 2025):

A Wall Street Journal article claims that Sam Altman is attempting to raise between 5 and 7 trillion dollars for a new chip-based project: https://www.wsj.com/tech/ai/sam-altman-seeks-trillions-of-dollars-to-reshape-business-of-chips-and-ai-89ab3db0

This is about 30% of US GDP, which is a lot of money. Will Sam have raised at least 1 trillion for something by the end of 2024? Doesn't count if the money is just generically for OpenAI, there has to be some new project that is being funded.
