Nvidia posted robust second-quarter results with revenue and profit exceeding analyst expectations, driven by strong demand for AI chips. However, the company did not record any sales for its advanced H20 AI chips in China due to regulatory constraints, leading to investor caution and a modest decline in stock price. Nvidia's forecast excludes China sales amid ongoing geopolitical issues, though potential licensed sales could generate significant revenue. The U.S.-China tech competition and regulatory scrutiny in both countries continue to cast shadows over Nvidia’s future growth opportunities. Nvidia also announced a new AI chip for robotics aimed at enabling autonomous physical AI applications, signaling a strategic push into the next wave of AI integration.
