Core Viewpoint - Nvidia's founder Jensen Huang is making significant efforts to regain market share in China's AI computing sector after losing ground to domestic chip companies during the U.S. export restrictions [4][5][8]. Group 1: Nvidia's Market Strategy - Jensen Huang's visit to China includes meetings with government officials and key industry players, aiming to restore confidence in Nvidia's operations in the region [4][5]. - Nvidia has received assurances from the U.S. government to resume sales of the H20 chip in China, which is a downgraded version of the H100 series designed to comply with export regulations [5][11]. - The company's market share in China has dropped from 95% during the export control period in 2022 to 50% due to the emergence of local competitors [8]. Group 2: Domestic Competitors - Chinese chip manufacturers have rapidly developed alternatives to Nvidia's H20 chip, including products from Kunlun, Moore Threads, Huawei, and Cambricon, which are aggressively targeting Nvidia's market share [7][12]. - Domestic chip companies have reported significant demand, with some experiencing a surge in orders and achieving substantial revenue growth, such as Cambricon's quarterly revenue increasing by 42.3 times [12][13]. - The competitive landscape is shifting as local firms focus on AI inference capabilities, which are less complex than training models, allowing them to better compete against Nvidia [14][15]. Group 3: Financial Implications - Nvidia's revenue loss due to the H20 ban is projected to be around $8 billion (approximately 57.3 billion yuan) in Q2 2025 [17]. - China represents a crucial market for Nvidia, contributing about 15% of its global revenue, equating to approximately $18 billion annually [16]. - The ongoing geopolitical tensions and export restrictions have created uncertainty for Nvidia's long-term prospects in China, despite the potential for short-term sales recovery with the H20's return [19][20].
