Nvidia Corp. (NVDA, Financials), the best producer of AI processors, is emerging from its best week in more than a year after a new endorsement from Elon Musk gave the stock further impetus. Shares jumped 12% last week on their greatest five-day run since May 2025.The rise added around $562 billion to Nvidia’s market capitalization, the greatest weekly gain on record. The announcement follows Musk’s statement that SpaceX will develop its future artificial intelligence infrastructure completely on Nvidia architecture, including the company’s upcoming Vera Rubin platform.That endorsement is important, as SpaceX is investing massively in AI infrastructure, but it’s only one piece of the demand narrative.Demand for high-end accelerators is still strong, with Amazon, Microsoft and other hyperscalers continuing to pump billions into data centers.The next test for investors is a quick one. Nvidia is set to disclose profits on Aug. 26, and expectations are already high after such a strong run.The final decision is whether the results and the guidance can justify the $562 billion investors just added to the company’s worth.
