South Korea’s stock market extended its decline for a second consecutive session as the momentum behind the recent AI-driven rally weakened. The benchmark KOSPI came under pressure as investor interest in chipmakers cooled, reversing one of the main themes that had supported the market.

According to the available report details, Seoul’s equity market has lost about $2.18 trillion in value during the slide. Tuesday’s drop carried into Wednesday, leaving the market on track for a deeper pullback as selling continued across key shares.

The retreat highlights how closely South Korean stocks have been tied to enthusiasm around artificial intelligence and semiconductor companies. As that excitement faded, the benchmark index saw a steep decline, with chip-related names appearing to bear much of the pressure.

For investors, the move signals a sharp shift in sentiment after a period of strong gains linked to AI expectations. With the KOSPI falling and interest in chipmakers softening, Seoul’s market is facing a tougher stretch after the earlier boom.
