Nvidia shares fell 2.86% as investor Mark Cuban warned that artificial intelligence infrastructure spending could make the market "crumble" if financing structures unravel, while Bank of America maintained its Buy rating and $350 price target ahead of the company's Aug. 26 earnings. Cuban said Nvidia is increasingly acting as both supplier and financier to the AI ecosystem through GPU purchase financing, revenue-sharing and minimum-revenue-guarantee arrangements. Analysts cited Nvidia's first-quarter fiscal 2026 investment exposure of $42.3 billion in private investments and $27 billion in conditional commitments, while Bank of America separately estimated roughly $70 billion in direct equity stakes across ecosystem partners, including $30 billion to OpenAI and up to $10 billion for Anthropic. Despite the financing debate and a broader selloff in chip stocks linked to rising oil prices and Treasury yields, BofA argued Nvidia remains undervalued at 16 times estimated 2027 earnings and expects second-quarter revenue of $94 billion to $95 billion, above the company's $91 billion forecast, with third-quarter revenue of $107 billion to $108 billion versus about $104 billion consensus. The bank said demand for next-generation Vera Rubin chips, tight GPU rental markets and Nvidia's pricing power should support an extended upgrade cycle and limit margin pressure from higher memory costs.
