NVIDIA posted its strongest weekly stock performance since May 2025, rising 11.6% as Elon Musk praised its upcoming Vera Rubin AI chip architecture and major cloud providers kept expanding spending on AI infrastructure. The shares added another 2.3% on Friday, August 7, to close at $223.96, lifting the company's market capitalization by about $562 billion over the week to a record one-week gain and pushing its total valuation to $5.42 trillion, ahead of Apple's $4.57 trillion. Musk, speaking during SpaceX's first earnings call since going public last week, called Vera Rubin "the most powerful AI computer on the planet" and said SpaceX's future AI infrastructure would fully transition to NVIDIA products, with plans to deploy nearly 10GW of computing capacity next year. Analysts said the immediate trigger came from Musk's remarks, but the broader driver remains heavy capital expenditure from hyperscalers (largest cloud operators) and persistent demand for GPUs (graphics processing units). Kate Leaman, Chief Market Analyst at AvaTrade, said the more important story is the scale of AI infrastructure investment and argued NVIDIA's momentum should hold as long as tech giants keep spending. BNP Paribas analyst Stefan Slowinski, however, warned that large commitments such as SpaceX's could tighten GPU supply further over the next 12 to 18 months, favoring customers with close NVIDIA ties such as CoreWeave, Nebius Group and Oracle while squeezing others. He said memory capacity is expanding at roughly 20% a year while AI demand is growing around 200% annually, a mismatch he believes could keep pricing favorable for AI chip suppliers and leave computing resources tight through 2027. Attention is now shifting to NVIDIA's quarterly earnings on August 26, where elevated expectations may leave the stock vulnerable to profit-taking even after strong results. The company has guided for second-quarter revenue of $91 billion, while some analysts expect nearly $95 billion, above the average analyst forecast of $91.9 billion.
