Stocks Surge to New Heights Amid Nvidia and Microsoft Gains

U.S. stock indexes hit record highs, driven by Nvidia's AI supercomputer news and Microsoft's investment in OpenAI. Nvidia plans to build seven AI supercomputers, boosting its stock. Microsoft gains from OpenAI restructuring. Major technology earnings loom, impacting market momentum.

On Tuesday, all three major U.S. stock indexes reached unprecedented closing highs, largely driven by a surge in Nvidia shares following the announcement of a partnership to build artificial intelligence supercomputers for the U.S. Department of Energy.

Nvidia's CEO, Jensen Huang, revealed the company's intent to develop seven supercomputers and disclosed $500 billion in AI chip bookings, causing Nvidia's stock to rise 5%, adding over $230 billion in market value. In tandem, Microsoft's stock gained 2% after securing a 27% stake in OpenAI, following its restructuring into a public benefit corporation.

Investors are keenly awaiting quarterly earnings from tech giants like Apple, Microsoft, and Amazon this week. Meanwhile, trade discussions between U.S. President Donald Trump and Chinese leader Xi Jinping continue to influence market sentiment amid the U.S. government shutdown.
