According to The Information, at the beginning of this month, the U.S. Department of Commerce began investigating whether TSMC provided chips to Huawei, after which TSMC stopped supplying chips to Sophgo, an AI company affiliated with Bitmain. It is currently unclear whether the relationship between Bitmain and TSMC has been affected or to what extent. The Information cited two informed sources stating that the U.S. Department of Commerce and TSMC recently discovered that "the chips produced by TSMC for Xiamen Sophgo have designs similar to Huawei's AI chips."
