SoftBank has completed its $40 billion investment commitment to OpenAI, sources told CNBC’s David Faber.

The Japanese investment giant sent over a final $22 billion to $22.5 billion last week, according to the sources familiar with the matter. SoftBank had previously syndicated $10 billion and invested $8 billion in the ChatGPT maker.
