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 investment last week, according to the sourced familiar with the matter. SoftBank had previously had 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, sources told Faber that the funding would be paid out over a 12 to 24 month period. Some of the money was slated to support OpenAI’s artificial intelligence infrastructure Stargate joint venture with Oracle and SoftBank.

Companies have been spending big in recent months to build out infrastructure to support booming demand for AI solutions and compute capacity needs.
