We may now know roughly how much money SoftBank and OpenAI are contributing toward Stargate, the massive infrastructure project to build data centers for OpenAI across the U.S.

SoftBank and OpenAI each plans to commit $19 billion of capital to Stargate, according to The Information. The two companies would then both own 40% of the joint venture.

Stargate, which also has buy-in from Middle East AI fund MGX, plans to funnel upwards of $500 billion into data centers to support OpenAI’s AI workloads. Partners in Stargate have initially pledged $100 billion, some of which is being put toward a facility in Abilene, Texas.

Elon Musk, who owns an AI company that competes with OpenAI, xAI, claimed this week on social media that Stargate “[doesn’t] actually have the money.” Altman responded in a post of his own, characterizing Musk’s assertion as “wrong.”
