The KOSPI closed at a record 7,490.05 on May 7, 2026, propelled by surging shares of Samsung Electronics and SK Hynix as institutional and retail investors poured into AI-driven semiconductor plays. Samsung Electronics traded at 279,500 won in pre-market activity, up 5.08%, while SK Hynix climbed 4.43% to 1.672 million won. The milestone comes as Samsung officially crossed the $1 trillion market capitalization threshold — making it only the second Asian company after TSMC to hit this landmark — underscoring the global AI investment boom's outsized impact on Korean chip giants.

Samsung crosses $1 trillion valuation on AI chip demand Samsung Electronics surged past the $1 trillion market cap mark after shares rose sharply on AI-driven demand, becoming only the second Asian company — after TSMC — to reach this milestone. Analysts note that rising analyst price targets following the KOSPI's move above 7,000 have continued to fuel bullish sentiment around the company.

SK Hynix company jacket becomes a cultural symbol of status SK Hynix's soaring stock price and record bonuses have turned the company's branded jacket into what Korean social media is calling a "dating meme" and status symbol. In South Korea's fiercely competitive job market, association with the semiconductor giant has taken on extraordinary social cachet, reflecting the halo effect of the AI chip boom on Korean corporate culture.

Top 1% ultra-high net worth investors pile into Samsung and SK Hynix On the afternoon of May 7, South Korea's top-tier ultra-high-net-worth investors began aggressively buying large semiconductor stocks including Samsung Electronics and SK Hynix, while also targeting industrial goods stocks such as LG Innotek. The buying wave coincides with record-breaking incentive payouts at both firms, though a new survey indicates that three out of four Koreans consider such "all-time" bonuses excessive.

Naver and Kakao launch AI-based 'citizen secretary' public service pilots Both Naver and Kakao have each launched pilot versions of an AI-based public service agent developed in cooperation with South Korea's Ministry of the Interior and Safety. The initiative marks a significant step in embedding large-scale AI into government-facing citizen services, building on each company's earlier push into agentic AI across search, shopping, and messaging platforms.

Kakao deepens AI integration with Google and OpenAI partnerships Kakao continues to advance its full-stack AI strategy by deepening integration between its flagship KakaoTalk messenger and ChatGPT, gradually rolling out new AI-driven features within the messaging platform. The company is targeting both consumer services and enterprise applications as part of its 2026 AI roadmap.

Naver pushes AI shopping and search tab for H1 2026 Naver is investing more than 1 trillion won (approximately US$691 million) to introduce an AI shopping agent followed by an AI-powered search tab in the second quarter of 2026. Travel and financial services AI agents are slated to follow, all housed in a new "AI Tab" coming to Naver's homepage and app. The aggressive investment signals Naver's intent to redefine its core platforms in the agentic AI era.

Startups & Investment

Korean AI chip startup Rebellions challenges global hardware players Korean AI processor startup Rebellions is drawing international attention for its chip technology, which observers say is redefining global AI hardware innovation. The company represents a broader trend of Korean deep tech startups moving up the semiconductor value chain, challenging established players in AI processing as demand for specialized inference chips accelerates.

Korean deep tech enters U.S. government market after tech prosperity deal The legal and market landscape for Korean deep tech companies pursuing U.S. government contracts has opened significantly following the Technology Prosperity Deal MOU signed by the White House and Seoul in October 2025. The deal covers AI, semiconductors, quantum computing, and space, with Korean companies committing $350 billion in investment. Legal experts note that the timing has rarely been better for Korean firms to enter U.S. federal procurement markets.

Policy & Industry

Korea's venture support agencies adopt AI to boost policy efficiency Korea's three main venture support agencies — KVIC, KOSI, and KOSME — are accelerating AI adoption across fund management, big data analysis, and corporate evaluation systems. The initiative aims to upgrade policy efficiency and modernize the infrastructure supporting Korea's startup ecosystem, reflecting the government's broader push to integrate AI into public sector operations ahead of anticipated productivity demands from the expanding AI economy.

AI era forces Korea's labor and capital into a new 'survival pact' As AI spreads from coding assistants to factory robots and automated hiring tools, South Korean labor and management are being compelled to renegotiate longstanding agreements in what experts are calling a new "survival pact." The Korea Times reports that both sides face unprecedented pressure to adapt to rapid automation, raising fundamental questions about employment structures, wages, and worker protections in the world's most AI-intensive economy.

What to Watch

• KOSPI momentum: With the index at a record 7,490 and analyst targets for Samsung and SK Hynix being revised upward, watch whether institutional buyers sustain the rally through the rest of May or whether profit-taking emerges near the 7,500 psychological level.
• Samsung HBM4 certification from Nvidia: Samsung is reportedly pushing to finalize its HBM4 leadership position, which could trigger a significant earnings upgrade cycle and further pressure SK Hynix's cost structure if Nvidia certifies Samsung's next-gen memory in the coming weeks.
• Korea-U.S. deep tech procurement deals: Following the Technology Prosperity Deal MOU, watch for the first concrete U.S. federal contract announcements by Korean semiconductor, AI, and quantum computing firms — which would mark a new chapter in the bilateral tech partnership.
