Taiwan's Keelung District Prosecutors' Office conducted raids on Supermicro's Taiwan office, along with the homes of six individuals and three affiliated company sites. The investigation is part of an expanded probe into the diversion of Nvidia AI chips to China, marking the first criminal case of its kind on the island.

The raids targeted not only Supermicro but also its supply-chain partners, including distributor Albatron Technology and data center operator Chief Telecom. According to a source cited by Bloomberg, the probe is uncovering potential violations related to the unauthorized export of advanced technology.

The investigation has already led to the summoning of six individuals for questioning, and Supermicro's shares fell 8% in U.S. trading following the news. The company has stated that it is cooperating with authorities and remains committed to protecting its advanced technologies and intellectual property.

The probe could have broader implications for companies involved in semiconductor supply chains, raising concerns about compliance, governance, and the potential for increased scrutiny of cross-border technology transfers. Market reactions suggest that such investigations may lead to heightened regulatory oversight and operational costs for firms operating in sensitive sectors.

As the investigation continues, the outcome could influence global semiconductor trade dynamics and the strategies of companies involved in AI chip manufacturing and distribution. The situation remains under active review, with further developments expected.
