Why did NVDA move on Sep 22, 2025?

Nvidia's stock rose 4.7% on September 22, 2025, driven by the announcement of a monumental strategic partnership with OpenAI. Under the deal, Nvidia committed to investing up to $100 billion in OpenAI, which OpenAI will in turn use to build and deploy next-generation AI data centers powered by millions of Nvidia GPU systems. This massive capital loop is expected to directly translate back into substantial, additive hardware revenue for Nvidia.
