Core Viewpoint - The article discusses the illegal export of Nvidia's advanced AI chips, particularly the B200 GPU, to China despite U.S. export restrictions, highlighting the emergence of a black market for these products [1][2][3]. Group 1: Nvidia's AI Chips and Black Market Activity - Following the tightening of U.S. export controls on AI chips to China, at least $1 billion worth of restricted Nvidia advanced AI processors have been shipped to mainland China [1]. - The B200 GPU has become the most popular chip in China's semiconductor black market, widely used by major U.S. companies like OpenAI, Google, and Meta for training AI systems [1][2]. - Despite the ban on selling advanced AI chips to China, it is legal for Chinese entities to receive and sell these chips as long as they pay the relevant border tariffs [1][2]. Group 2: Distribution and Sales Channels - A company named "Gate of the Era" has emerged as a major distributor of the B200, having sold nearly $400 million worth of these products [3]. - The B200 racks are sold at prices ranging from 3 million to 3.5 million RMB (approximately $489,000), which is lower than the initial price of over 4 million RMB [3]. - The sales of these chips are facilitated through various distributors in provinces like Guangdong, Zhejiang, and Anhui, with significant quantities being sold to data center providers [2][3]. Group 3: Market Dynamics and Future Outlook - The demand for Nvidia's B200 chips remains high due to their performance and relative ease of maintenance, despite U.S. export controls [11]. - Following the easing of the H20 export ban, the black market sales of B200 and other restricted Nvidia chips have reportedly decreased as companies weigh their options [13]. - Southeast Asian countries are becoming key transit points for Chinese companies to acquire restricted chips, with potential tightening of export controls being discussed by the U.S. government [13][15]. Group 4: Repair and Maintenance Services - There is a growing demand for repair services for Nvidia's high-end chips, with some companies in China specializing in the maintenance of H100 and A100 chips that have entered the market through special channels [17]. - The average monthly repair volume for these AI chips has reached 500 units, indicating a significant market need for maintenance services [17][18]. - The introduction of the H20 chip has seen limited market acceptance due to its high price and inability to meet the demands for training large language models [18].
