These servers, originally produced by **Super Micro Computer**, were allegedly rerouted through Thailand before ending up in China, with tech giant **Alibaba** identified among the ultimate recipients. According to details revealed by US prosecutors, the scheme allegedly involved disguising shipments of US-made AI hardware by funneling them through Taiwan and Southeast Asia. This elaborate repackaging and rerouting reportedly enabled these high-end servers to evade US export controls, which restrict the sale of cutting-edge technology to China for national security reasons. The timeline of the alleged activity includes shipments valued at over $2.5 billion, with a notable series of transactions exceeding $500 million occurring within a narrow window from April to mid-May 2025. The charges touch on key figures from **Super Micro Computer**, including co-founder Yih-Shyan Liaw and sales manager Ruei-Tsang Chang, alongside a contractor, all accused of orchestrating the scheme. While **Alibaba** has publicly stated it holds no business ties with Super Micro, OBON, or involved middlemen, the investigation raises questions about the efficacy of existing export enforcement and compliance systems. The US government's ban on Nvidia's most advanced chips to China, initiated in 2022, aimed to curb the potential military use of these technologies, though it has permitted some sales of Nvidia's H200 series under strict conditions since earlier this year. This smuggling case also echoes in the legal arena beyond government scrutiny. Shareholders of **Super Micro Computer** have initiated a securities fraud lawsuit, claiming the company downplayed its exposure to illegal sales into China, potentially inflating its financial health and stock value. Market responses have been mixed. On the day of the report, Nvidia's shares gained about 1.8%, while Super Micro Computer's stock slipped by 3%, and Alibaba faced a mild decline. The volatility reflects lingering uncertainties around export restrictions and geopolitical tensions. The case underscores the global challenge of regulating high-tech products with dual civilian and military applications. It also brings to the forefront Thailand's role as a transit point in these complex cross-border supply chains-raising eyebrows about regional compliance standards. Investigations are ongoing, and while official statements from the involved companies remain limited, the allegations continue to stir conversations about tech trade security and regulation enforcement in the AI era. ### Related Stocks - [SMCI.US](https://longbridge.com/en/quote/SMCI.US.md) - [SMCL.US](https://longbridge.com/en/quote/SMCL.US.md) - [512760.CN](https://longbridge.com/en/quote/512760.CN.md) - [SMH.US](https://longbridge.com/en/quote/SMH.US.md) - [NVDQ.US](https://longbridge.com/en/quote/NVDQ.US.md) - [588780.CN](https://longbridge.com/en/quote/588780.CN.md) - [NVDU.US](https://longbridge.com/en/quote/NVDU.US.md) - [SMCX.US](https://longbridge.com/en/quote/SMCX.US.md) - [159801.CN](https://longbridge.com/en/quote/159801.CN.md) - [SMCY.US](https://longbridge.com/en/quote/SMCY.US.md) - [NVDX.US](https://longbridge.com/en/quote/NVDX.US.md) - [588170.CN](https://longbridge.com/en/quote/588170.CN.md) - [NVDS.US](https://longbridge.com/en/quote/NVDS.US.md) - [159325.CN](https://longbridge.com/en/quote/159325.CN.md) - [NVDY.US](https://longbridge.com/en/quote/NVDY.US.md) - [PSI.US](https://longbridge.com/en/quote/PSI.US.md) - [XSD.US](https://longbridge.com/en/quote/XSD.US.md) - [SOXX.US](https://longbridge.com/en/quote/SOXX.US.md) - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [BABA.US](https://longbridge.com/en/quote/BABA.US.md) - [09988.HK](https://longbridge.com/en/quote/09988.HK.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) - [89988.HK](https://longbridge.com/en/quote/89988.HK.md) - [HBBD.SG](https://longbridge.com/en/quote/HBBD.SG.md) ## Related News & Research - [President Trump Just Opened a Multi-Million Dollar Position in This Chip Stock](https://longbridge.com/en/news/286447779.md) - [Cerebras (CBRS) IPO: Why It's Different from Nvidia, AMD](https://longbridge.com/en/news/286449201.md) - [Cerebras's stock set for blast off, as early indications point to a near doubling](https://longbridge.com/en/news/286434594.md) - [Cerebras's stock rockets out of the gate, in a sign the AI boom is as strong as ever](https://longbridge.com/en/news/286448448.md) - [Jensen Huang nears $200B as Nvidia tops $5.5T before China talks](https://longbridge.com/en/news/286370644.md)
