SoftBank, OpenAI, and Oracle are launching a $500 billion joint venture named Stargate to fund AI infrastructure in the U.S. The initiative, praised by President Trump, aims to deploy $100 billion immediately for projects like data centers and cancer research.

The Stargate announcement prompted immediate skepticism over whether it would come to fruition, or represented new spending by the companies.
