KOSPI 4500 milestone 2026: Seoul stocks hit record high as tech rallies

1 min readSource

KOSPI hits a historic 4,500 milestone on Jan 6, 2026, closing at 4,525.48. Led by semiconductors and retail buying of 597B won, Seoul stocks reach an all-time high.

The 4,500 ceiling has finally shattered. On January 6, 2026, Seoul's benchmark index soared to an unprecedented peak, propelled by a surge in semiconductors and shipbuilders. It's a massive leap that comes just one session after the market breached the 4,400-point threshold.

How KOSPI 4500 milestone 2026 was achieved

According to Yonhap, the KOSPI jumped 67.96 points, or 1.52 percent, to finish at a record 4,525.48. Although the index opened lower despite gains on Wall Street, it quickly reversed course as retail investors aggressively scooped up large-cap technology stocks. Trading volume was heavy, totaling 25.27 trillion won ($17.4 billion).

Retail Power vs. Institutional Retreat

Individual buyers were the main engine behind the rally, purchasing a net 597.55 billion won worth of shares. This offset net selling from foreigners and institutions, who sold 618.83 billion won and 68.93 billion won respectively. Meanwhile, the Korean won weakened slightly, ending at 1,445.50 against the U.S. dollar.
