On the 20th morning, Doosan shares rose more than 5%. Expectations grew that Doosan will be the sole supplier of high-quality copper-clad laminate (CCL) for Nvidia's next-generation artificial intelligence (AI) chips.
As of 9:40 a.m. on the 20th, Doosan was trading at 957,000 won on the Korea Exchange, up 50,000 won (5.51%) from the previous day. Early in the session it surged to 1 million won, briefly staying in the "emperor stock (a share priced at 1 million won)" range.
Earlier, Taiwan's EMC, a rival to Doosan's Electronics Business Group (BG), recently failed Nvidia's GB300 computing tray qualification (Qual) test. With expectations rising that a monopoly supply chain for Doosan will form, buying interest appears to have poured in.
Kim Su-hyeon, head of research at DS Investment & Securities, said, "With the Taiwanese competitor failing the qual test, the likelihood of Doosan's exclusive supply has become very high," and added, "From the third quarter of next year, when Rubin-related revenue could begin, there is a high possibility that Doosan's exclusive supply window will form, and a sharp increase in revenue is expected in the fourth quarter of next year."
