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 sources familiar with the matter, who asked not to be named in order to discuss details of the transaction.
SoftBank had previously syndicated $10 billion and invested $8 billion in the ChatGPT maker. The investment takes SoftBank's stake in the company above 10%.
CNBC reported in February that the company was finalizing a $40 billion investment in the Sam Altman-run startup at a $260 billion pre-money valuation.
At the time, Faber reported that the funding would be paid out over a 12-to-24-month period. Some money was slated to support OpenAI's artificial intelligence infrastructure Stargate joint venture with Oracle and SoftBank.
