OpenAI is putting its focus on AI infrastructure with Stargate at a time when rivals like China's DeepSeek are closing the gap on its AI models.

We may now know roughly how much money SoftBank and OpenAI are contributing toward Stargate, OpenAI's massive data center project.

OpenAI and Japanese conglomerate SoftBank will each commit $19 billion to fund a joint venture to develop data centers for artificial intelligence in the U.S., the Information reported on Wednesday, citing OpenAI CEO Sam Altman speaking to colleagues.

Microsoft will no longer be the exclusive provider of new cloud computing capacity to OpenAI — a new twist in their relationship that clears the way for OpenAI to work with Oracle and others on the $500 billion Stargate AI project announced by the companies Tuesday with President Trump at the White House.

On Tuesday, OpenAI, SoftBank, Oracle, and MGX announced plans to form Stargate, a new company that will invest $500 billion in AI computing infrastructure across the United States over four years. The announcement came during a White House meeting with President Donald Trump, who called it the "largest AI infrastructure project in history."

Stargate, a high-profile artificial intelligence infrastructure project trumpeted by US President Donald Trump this week, will exclusively serve ChatGPT maker OpenAI, according to people familiar with the matter.
