Nvidia's Rubin chip debut faces AI spending doubts

Nvidia's upcoming results will test whether its new Rubin chips can sustain growth, as investors question the durability of the AI spending boom. The chipmaker faces scrutiny over its role in financing deals that may inflate demand. Analysts expect second-quarter revenue to nearly double to $92.18 billion, driven by data center sales. Nvidia has helped arrange $500 billion in financing for customers and guaranteed up to $105 billion for OpenAI's Ohio data center, raising concerns about circular deals. The Rubin ramp-up is critical amid competition from custom chips and Intel, AMD processors. Morgan Stanley estimates these chips could contribute nearly $9 billion in third-quarter sales. Analysts forecast an 82.8% rise in third-quarter sales to $104.20 billion.
