Nvidia B300 servers hit $1 million in China as US export restrictions tighten supply

Nvidia B300 Servers Command Million-Dollar Premium in China

Nvidia B300 servers are now fetching approximately 7 million yuan, roughly $1 million per unit, in China, nearly double their US list price of around $550,000, according to industry sources 1

. This represents a dramatic escalation from approximately 4 million yuan late last year, reflecting a scarcity premium driven by tighter US export restrictions and the near-collapse of grey market chip smuggling channels that Chinese AI companies had relied upon 1

.

The B300, packed with 288 GB of high-bandwidth memory and delivering 14 petaFLOPS of computing power at FP4 precision, ranks among the most powerful options available for AI inference workloads 3

. Each server houses eight B300 GPUs and is critical for Chinese technology companies scrambling to monetize their AI models and compete on inference efficiency, the cost of generating tokens, the basic unit of AI text output 1

Supermicro Co-founder Arrest Triggers Supply Chain Collapse

The inflection point in the price surge traces directly to the arrest of Yih-Shyan 'Wally' Liaw, co-founder of Supermicro, on March 19, 2026 1

1

. US federal prosecutors unsealed an indictment alleging that Liaw, Supermicro's Taiwan general manager Ruei-Tsang Chang, and contractor Ting-Wei Sun conspired to divert roughly $2.5 billion in Supermicro servers containing Nvidia's export-controlled Blackwell-class AI chips to Chinese buyers via a Southeast Asian pass-through company 1

.

The scheme involved swapping serial numbers using heat guns, fabricating paperwork, and using fake replica servers to deceive government auditors 1

1

. Supermicro's shares fell 33% on the day the indictment was unsealed, erasing more than $6 billion in market capitalization 1

1

. This prosecution represents the highest-profile enforcement action yet under the AI chip export control regime the US has been tightening since 2022, and its effect on grey market supply appears to have been immediate 1

AI Server Rentals Surge as Chinese Companies Seek Alternatives

Rental prices for B300 servers in China have surged alongside sale prices, with short-term contracts reportedly reaching as high as 190,000 yuan per month on one-year contracts 1

. Many Chinese AI companies are deliberately structuring arrangements to avoid holding Nvidia hardware directly on their balance sheets, fearing exposure to US sanctions 1

The demand surge reflects explosive growth in Chinese AI usage. Chinese AI models accounted for 32% of global token usage in March 2026, up from 5% a year earlier, driven by advances in coding and agentic capabilities, according to Morgan Stanley 2

US Semiconductor Export Controls Create Compounding Restrictions

The B300 scarcity compounds a separate restriction that hit Chinese AI companies in early 2025. On April 9, 2025, the US government informed Nvidia that it required a license to export its H20 chips, the China-specific GPU Nvidia had designed to comply with earlier export control rules, to the Chinese market 1

. Nvidia took a $4.5 billion charge in Q1 FY2026 on excess H20 inventory and purchase obligations, and was unable to ship an additional $2.5 billion of H20 revenue that quarter 1

.

The H20 had been Chinese companies' primary access point for compliant Nvidia GPU hardware; its restriction eliminated that option 1

1

. Despite receiving approvals from both governments for exports of H200 chips, the hardware has yet to be shipped to China as the two sides remain at odds over the conditions governing its sale 3

Nvidia Distances Itself as Enforcement Tightens

Nvidia has publicly distanced itself from the grey market supply chain, stating that the B300 is restricted from sale in China and that partners must comply strictly with export rules 1

. "As systems become increasingly large and complex, unlawful diversion is a recipe for failure," Nvidia warned, noting that diverted hardware will not receive company support 3

.

The current price dynamic unfolds against an escalating policy backdrop. Last week, the US House Foreign Affairs Committee advanced the MATCH Act on April 22 in what lawmakers described as the largest semiconductor export control markup in congressional history 1

1

. The bill would require the Netherlands and Japan to align their own chip equipment restrictions with US rules, cutting off ASML's remaining China sales and banning the servicing of already-installed machines 1

Geopolitical Tensions Reshape AI Hardware Market Share

Even with export restrictions, Nvidia still holds about 55% of China's AI chip market, a notable share given its top products technically aren't supposed to be sold there 2

. Advanced Micro Devices sits at just 4%, while Huawei Technologies and other domestic chipmakers are angling to use the disruption to chip away at Nvidia's lead 2

.

The combined effect of H20 chips being restricted, the B300 grey market being disrupted, and domestic Chinese AI accelerators not yet competitive with Nvidia's highest-end systems for frontier model training has produced the scarcity premium now reflected in advanced AI hardware pricing 1

. As AI compute scarcity intensifies and supply chains face mounting pressure from geopolitical tensions, Chinese tech companies face difficult choices between paying extreme premiums, accepting inferior domestic alternatives, or restructuring operations to work within tightening constraints.
