South Korea on Monday unveiled a sweeping package of AI and semiconductor "megaprojects" anchored by its two chip giants, Samsung and SK Hynix, according to multiple outlets covering the announcement.

The headline figures vary widely across reports. CNN reported that President Lee Jae Myung pledged investments worth more than $576 billion, a number echoed by Finimize and Huawei Central. Al Jazeera framed the drive as more than $1 trillion, while Tech Times cited a $649 billion Samsung-led push into chips, data centers and robots. TRT World put the bet at $1.2 trillion, and bloomingbit reported SK alone unveiling a $1.5 trillion plan. Yonhap News Agency reported that SK Group would invest 2,100 trillion won to build AI infrastructure nationwide. The differing totals appear to reflect different ways of counting public and private commitments over time, so the exact scale is best read as a range.

The Korea Herald reported the plan is designed to power regional growth beyond Seoul, with Finimize similarly noting an emphasis on chips and AI "beyond Seoul." Crypto Briefing reported that Samsung and SK Hynix plan massive new chip fabrication sites to meet AI demand, including a roughly $520 billion plant project. According to theinvestor.co.kr, President Lee called the Samsung and SK chiefs "national heroes" in what it described as a 900-trillion-won chip push.

Markets took notice. Reuters reported that the South Korean chip push helped steady sentiment across choppy Asian shares, even as investors also watched developments around an Iran truce.

Why it matters: South Korea is one of the world's most important suppliers of the memory and logic chips that power AI, and a state-backed spending drive of this size signals how fiercely governments now compete to own the hardware behind the AI boom.
