Despite the United States placing strict limits on the export of high-performance AI chips to China, an estimated $1 billion worth of Nvidia processors have reportedly made their way into the country through black market channels.
The revelation, detailed in a recent investigation by the Financial Times, highlights the difficulty of containing the spread of advanced technology in a globalized supply chain. The chips in question belong to Nvidia’s B200 series, part of its Blackwell architecture, which debuted in 2023 and is widely regarded as some of the most advanced AI hardware available.
These chips are designed for large-scale data processing and machine learning applications. They’re critical to powering generative AI systems, like those developed by U.S. companies such as Amazon, Microsoft, and Google. And yet, despite a ban on their sale to China, many are now reportedly being sold through unauthorized distributors in nearby countries such as Malaysia and Thailand.
Smuggled AI Racks Sold as Plug-and-Play Systems
The Financial Times report notes that these chips aren’t just entering China as loose components. They are reportedly being sold as preassembled rack-mounted systems, already configured with software, allowing them to be installed directly into Chinese datacenters. This “plug-and-play” nature minimizes the need for technical expertise, making the hardware attractive to buyers trying to fast-track AI development projects.
Vendors are said to be advertising the units on Chinese social media platforms, offering optional testing and even providing after-sales support. In many cases, buyers are paying a steep premium—up to 50% more than what authorized customers in other regions might pay. Despite the inflated costs, demand appears to be strong.
The Growing Importance of Nvidia’s AI Hardware
Nvidia’s AI chips have become the backbone of generative AI research and development. The B200 chips, along with other models like the H100, H200, and the 5090, have powered a wave of innovation in AI across the globe. However, this same popularity has made them prime targets for illicit trade, particularly in countries facing restrictions.
China has long sought to boost its domestic AI capabilities. Yet its homegrown semiconductor industry still lags behind that of the U.S. and Taiwan. Most of Nvidia’s chips are manufactured by Taiwan Semiconductor Manufacturing Company (TSMC)—a firm that has become central to the global tech supply chain, and a flashpoint in U.S.-China geopolitical tensions.
Chinese firms have made repeated attempts to close this gap, sometimes by reverse engineering foreign designs. But the ability to directly acquire advanced hardware, even through unauthorized means, provides a major shortcut—albeit a risky one.
Tighter U.S. Trade Policies Still Falling Short
In response to concerns over the potential military and strategic uses of AI chips, the U.S. has ramped up export controls over the past few years. Lawmakers in Washington—particularly those critical of China’s trade practices—have pushed for increasingly aggressive restrictions on high-tech exports.
Under former President Donald Trump’s administration, a sweeping ban was implemented that prohibited Nvidia from selling any AI chips to China. That policy was slightly revised earlier this year, allowing only a few lower-powered models like the H20 to be sold. More powerful chips, including the B200, remain off-limits.
Yet despite these efforts, the underground trade has continued to thrive. Smuggled chips are not only reaching Chinese customers, but also being sold in large quantities. And it’s not just the B200s—other restricted models have also appeared for sale, indicating widespread leakage from the legitimate supply chain.
Nvidia: No Denial, But Distance Maintained
Nvidia, which recently became the world’s most valuable chipmaker with a $4 trillion market cap, has not explicitly confirmed or denied the scale of the black market reported. The company maintains that true AI infrastructure requires long-term support and servicing—something it says can only be provided for authorized products.
Still, the widespread availability of Nvidia systems on Chinese social platforms tells a different story. Vendors claim the systems are easy to deploy and capable of running demanding AI workloads. That raises concerns about whether the company’s chips are slipping out of official distribution networks or being resold by third-party intermediaries.
Nvidia’s official stance is that it does not support or authorize these backchannel transactions. However, with such large quantities involved, the situation could draw increased scrutiny from U.S. authorities and lawmakers.
Nvidia’s Delicate Relationship With China
Nvidia’s CEO Jensen Huang, born in Taiwan, has often spoken about China being a vital market—not only for sales but also for sourcing technical talent. His views on maintaining access to Chinese customers are believed to have influenced recent discussions with the U.S. government regarding export policy revisions.
That stance puts Nvidia in a difficult position. The company must navigate between maintaining relationships in one of the world’s largest tech markets and complying with intensifying U.S. trade restrictions.
Other American tech companies are pulling back. Amazon Web Services, for example, recently shuttered its AI lab in China, citing restructuring efforts and shifting strategic priorities. Although it’s unclear if U.S.-China tensions were the deciding factor, the move reflects the growing unease many U.S. firms feel operating in the region.
