OpenAI wants to remain the most valuable private company in the world. But it needs money to do so: 40 billion US dollars.

SoftBank could invest $15 billion to $25 billion directly into Microsoft-backed OpenAI, some of which may be used to pay for OpenAI's commitment to Stargate, Reuters had reported on Wednesday, citing a person familiar with the matter.
