South Korea’s Kospi rose 3.29 percent to 5,823.85 as of 9:16 a.m. on Wednesday in Seoul, extending an opening gain of 2.23 percent, while the Kosdaq rose 3.24 percent to 767.93. Samsung Electronics rose 4.73 percent and SK Hynix rose 3.13 percent after Hynix reported record third quarter operating profit of 83.33 trillion won, 9.3 percent above the Yonhap Infomax compiled consensus, alongside an additional 60 trillion won shareholder return plan. Yonhap attributed the advance to the Hynix results and to revived expectations for AI investment after Anthropic’s push toward an initial public offering lifted all three major New York indices overnight, with foreign investors net buyers of Kospi shares for a second straight day.
Kospi surges 3.3 percent on Hynix earnings and Anthropic momentum
South Korea's Kospi rose 3.29 percent to 5,823.85 in early Wednesday trade in Seoul, with Samsung Electronics up 4.73 percent and SK Hynix up 3.13 percent, as Hynix's record third quarter earnings and Anthropic's initial public offering push lifted technology shares.
Why it matters: Seoul's chip heavy index is moving sharply on the same AI earnings impulse that set the tone overnight in New York, a sign the AI trade's momentum is broadening across Asian markets rather than fading.
