SK Hynix’s nearly fully booked HBM capacity through 2025 anchors Yoolim Lee’s coverage of South Korea’s AI-chip resurgence and Samsung’s response.

Who they are

Yoolim Lee is a person whose associated coverage centers on South Korean technology and business, particularly Samsung and SK Hynix, while also tracking the country’s AI startups, gaming companies, corporate governance and labor disputes.

The recent arc

Coverage reached its recent high point in 2023Q4 before shifting decisively through 2024 toward the AI semiconductor cycle. SK Hynix’s return to profit in the 2024-01-25 results, its Q1 profit surge, and its statement that HBM capacity was nearly booked through 2025 culminated in coverage of record Q3 revenue on continuing AI-chip demand. Samsung appeared both as a consumer-device company, with the Galaxy Ring and pricier Fold6 and Flip6 launches, and as a chipmaker under competitive pressure.

The later stories broaden that semiconductor and corporate lens rather than abandoning it. They include Samsung’s first-ever union strike in June 2024, compensation changes tying bonuses to stock performance in 2025, Jay Y. Lee’s Supreme Court reprieve, Rebellions’ $250 million funding round, and Tesla’s plan to source AI5 chips from Samsung and TSMC. That progression links company performance, workforce relations, governance and the effort to build an AI-hardware ecosystem in South Korea.

The tension

The central tension is Samsung’s effort to maintain technological and commercial leadership while SK Hynix benefits from AI-driven demand for high-bandwidth memory and Chinese rivals challenge Samsung in foldables. The coverage also shows that this contest is not purely product-led: Samsung’s labor disputes, executive incentives and Jay Y. Lee’s legal overhang sit alongside SK Hynix’s capacity constraints and Rebellions’ emergence as a domestic AI-chip contender.

Why it matters

If AI infrastructure demand remains durable, the stories suggest South Korea’s technology sector will be shaped increasingly by control of advanced memory supply, manufacturing execution and the ability to convert that position into broader AI platforms and customers. Samsung’s role in Tesla-linked chip production and SK Hynix’s HBM momentum make that outcome consequential, though demand durability, competitive pressure and internal labor and governance issues remain meaningful constraints.
