Top Story

Samsung Electronics has commenced HBM4 shipments, marking a significant milestone in the AI chip race even as SK Hynix reportedly lags behind in next-generation memory development. The development is overshadowed by a looming threat: a potential 50,000-worker strike in just five days that could disrupt AI chip supply chains critical to global technology infrastructure. Both Samsung and SK Hynix sharply increased their R&D spending in Q1 2026, with SK Hynix's outlay surging 68% year-on-year, reflecting intensifying competition in AI memory development.

Nomura Dramatically Raises Samsung and SK Hynix Price Targets Despite US Chip Selloff Nomura recently raised Samsung Electronics' target price to 590,000 won from 340,000 won and SK Hynix's to 4 million won from 2.34 million won in a recent report — a dramatic upward revision that signals continued analyst conviction in Korean chipmakers' AI-driven growth trajectory.

Samsung Begins HBM4 Shipments Amid Strike Threat and R&D Race Samsung Electronics has started shipping HBM4 while both it and SK Hynix posted sharp R&D spending increases in Q1 2026. SK Hynix's R&D outlay surged as much as 68% year-on-year, and Samsung's also rose significantly, as both firms race to dominate the high-bandwidth memory market for AI applications.

Glass Substrate Race Heats Up Across Korean Tech Giants SKC, Samsung Electro-Mechanics, and LG Innotek all plan to achieve mass production of glass substrates between 2026 and 2028, setting up a three-way competition that will directly influence packaging costs and time-to-market for both Samsung and SK Hynix's memory products for AI accelerators.

Naver · Kakao · LINE

No recent (post-May 15) breaking news was confirmed for Naver, Kakao, or LINE specifically.

The most recent verified reporting on these companies from research results dates to February–March 2026, covering Naver's planned AI Tab rollout for its homepage, Kakao's agentic AI push for messaging services, and the joint "AI citizen secretary" public service pilots by both companies. While these remain active strategic directions, no new announcements after May 15, 2026 were confirmed in today's research results.

Verified background (pre-cutoff context): Naver launched an AI shopping agent in Q1 2026 and planned an AI-powered search tab in Q2 2026, while both Naver and Kakao launched an "AI citizen secretary" pilot allowing users to access government services through conversational AI within existing consumer platforms without installing a separate application.

Note: No confirmed fresh Naver/Kakao/LINE developments after May 15 were found in today's research sweep. This section will be updated as new information surfaces.

Startups & Investment

Korea's Physical AI Ecosystem Takes Off — Weekly Startup Roundup Korea's startup ecosystem is rapidly shifting toward Physical AI, robotics, and vertical AI as fresh capital flows into real-world applications, according to Korean Startup Weekly News #118. The report highlights a notable pivot from pure software-focused AI toward embodied intelligence platforms, robotics, and sector-specific AI tools across Korean startups.

Xpanner Raises $18M Series B for Construction Site Automation Xpanner, a startup automating construction work through robotics and physical AI technology, has raised $18 million in a Series B round led by existing backer Korea Investment Partners (KIP). The company offers "Automation as a Service" to construction sites, combining robotics hardware with AI software — a clear example of Korea's growing Physical AI investment trend.

Policy & Industry

Korea's Ministry of SMEs and Startups Expands Regional Venture Funds The Ministry of SMEs and Startups announced an expansion of regional venture funds, aiming to distribute startup capital more broadly across Korea beyond the Seoul metropolitan area. The initiative reflects the government's push to build a more geographically diverse innovation ecosystem and reduce concentration risk in the capital region's startup scene.

South Korea to Launch Sovereign Wealth Fund for Late-Stage Startups South Korea announced plans to launch a sovereign wealth fund focused on late-stage startups and strategic industries, signaling a more active role for government capital in supporting Korean companies scaling into global markets — particularly in AI, semiconductors, and advanced manufacturing.

Korea-UAE AI Infrastructure and Semiconductor Investment Forum Korea and the UAE held an AI Infrastructure and Semiconductor Investment Forum in Seoul, bringing together 25 UAE officials from Core42, MGX, Mubadala, and other institutions to discuss strategic AI cooperation. The forum underscores Korea's active diplomacy to attract Middle Eastern sovereign capital into its semiconductor and AI ecosystem.

What to Watch

• Samsung Strike Risk: With 50,000 workers potentially striking in five days, monitor labor negotiations closely — a work stoppage could disrupt HBM4 and broader AI chip supply chains at a critical moment for the AI hardware market.
• Nomura Price Target Catalysts: Watch whether Nomura's dramatic upward revisions for Samsung (590,000 won) and SK Hynix (4 million won) spark a broader analyst upgrade cycle that could accelerate foreign inflows into Korean chip stocks.
• Physical AI Funding Wave: Track whether Korea's pivot toward Physical AI, robotics, and vertical AI in startups produces additional large funding rounds beyond Xpanner's $18M Series B — the next quarterly startup funding report from the Ministry of SMEs will be a key indicator.
