Top Story

Samsung Electronics held its top position among Korea's 500 largest companies by revenue in 2024, recording 333.6 trillion won, while SK Hynix made a dramatic climb to fifth place on the back of surging high-bandwidth memory (HBM) demand driven by AI infrastructure build-outs globally. The ranking shift underscores how the AI semiconductor cycle is fundamentally reordering Korea's corporate hierarchy. SK Hynix's market cap also recently topped 1,000 trillion won, reflecting how investors are pricing in the company's dominant position in the HBM supply chain alongside Nvidia and other AI hardware giants.

Samsung Electronics Tops Stock Gifts to Minors, Accounting for 56.3% of Transactions Samsung Electronics was the most-gifted domestic stock to minor children by KB Securities customers last month, accounting for 56.3% of all such transactions, followed by Kia and Kakao. The data highlights Samsung's continued status as the "forever stock" in Korean retail investment culture, even as its share price has lagged SK Hynix's recent rally.

Bond-Mixed ETFs Holding Samsung and SK Hynix Draw Heavy Inflows Three of the 17 ETFs newly listed on the KOSPI market last month were bond-mixed products holding Samsung Electronics and SK Hynix, according to the Korea Exchange (KRX). The concentrated inflows into these products have intensified competition among asset managers and reflect broad retail and institutional appetite for exposure to Korea's two chip giants amid the ongoing AI semiconductor boom.

Samsung Shares Lag SK Hynix Rally as Analysts Cite Strike Risk Bloomberg reported that Samsung Electronics shares' recent underperformance against SK Hynix may intensify as a looming workers' strike weighs on South Korea's most valuable company. Analysts note that the labor uncertainty adds a risk premium to Samsung stock absent from SK Hynix's valuation, widening the performance gap between the two chipmakers even as both benefit from robust HBM demand.

Korea's Venture Support Agencies Accelerate AI Adoption for Policy Efficiency Korea's major venture support agencies — KVIC, KOSI, and KOSME — are adopting AI technologies to upgrade fund management, big data analysis, and corporate evaluation systems, aiming to dramatically boost policy efficiency. The move signals that Korea's government-linked financial infrastructure is embracing AI-driven automation beyond just private sector applications, potentially reshaping how startup funding decisions are evaluated and distributed at scale.

Kakao Remains Popular Among Retail Stock Gift Recipients Kakao appeared as the third most popular stock gifted to minor children by KB Securities customers in April, following Samsung Electronics and Kia. The inclusion reflects Kakao's continued relevance as a household brand in Korea's retail investment narrative despite the broader tech-sector volatility experienced over the past year.

Naver and Kakao AI Agent Push Forms Government Partnership Layer Earlier reporting confirmed that Naver and Kakao have each launched pilot versions of AI-based public service agents developed in cooperation with Korea's Ministry of the Interior and Safety — a "citizen secretary" initiative that positions both platforms as critical government technology partners. With Korea's venture agencies now deploying AI internally, the ecosystem of government-Naver-Kakao AI collaboration appears to be expanding meaningfully in 2026.

Startups & Investment

Rebellions Redefines AI Chip Innovation, Challenging Global Incumbents Korean AI chip startup Rebellions is gaining international recognition for its AI processor technology, with analysts noting the company is directly challenging established global AI hardware players. The startup's progress reflects a broader ambition within Korea's deep tech ecosystem to capture a share of the rapidly expanding AI accelerator market beyond the memory chip segment dominated by Samsung and SK Hynix.

Korea's Deep Tech Enters U.S. Government Market — Legal Landscape Explained The timing has "rarely been better" for Korean companies to pursue U.S. government contracts, according to the National Law Review, following the White House and Republic of Korea signing a Technology Prosperity Deal MOU in October 2025 covering AI, semiconductors, quantum computing, and space. Korean companies have committed $350 billion in related investment. Legal observers note the MOU opens significant procurement pathways but requires Korean firms to navigate complex U.S. national security and contracting frameworks carefully.

Policy & Industry

South Korea Invests $5.7 Billion to Boost AI Industry via National Growth Fund South Korea is accelerating investment to strengthen its AI competitiveness, committing $5.7 billion through the National Growth Fund. The government is expanding support beyond pure AI applications to encompass energy infrastructure needed to power AI workloads. The announcement positions Korea as one of the most aggressive state-backed investors in AI industrial policy globally, complementing the private sector momentum from Samsung, SK Hynix, and the growing startup ecosystem around AI hardware and software.
