Nvidia faces investor scrutiny ahead of May 20 earnings as the company maintains 0% official GPU market share in China due to U.S. restrictions on advanced chips, though a booming gray market suggests significant smuggled hardware sales. Despite high analyst expectations (96% Buy rating, 40% upside consensus), the key risk is determining how much backlogged revenue stems from China and how U.S. export controls will impact results. The company’s trillion-dollar backlog through 2027 and strong datacenter demand from hyperscalers provide positive catalysts, though stock price action has been tepid compared to other chip stocks.
