SK Hynix’s Trillion-Dollar Dream Comes With a $14 Billion IPO, a Labour Fight, and a Samsung Strike Windfall

SK Hynix has posted a record operating profit of 45 trillion won, pushing its market capitalisation to roughly $948 billion and within striking distance of the trillion-dollar mark. The stock has surged 158% since the start of the year, currently trading at 1,745,000 won, though it sits 11.69% below its recent high. Yet for all the celebration, the memory giant is juggling a subcontractor revolt, a potential windfall from a rival’s walkout, and ambitious plans to raise up to $14 billion in a US listing.

The company’s technological edge was underlined at Seoul’s Korean Inventor’s Day, where two key developers received top honours. Chief Development Officer Ahn Hyun was awarded the Gold Tower Order of Industrial Service Merit for his work on next-generation HBM, including the HBM4 platform, mass-production systems, and high-layer NAND. NAND specialist Hyungjin Choi earned a Presidential Citation for breakthroughs in 4D-NAND, covering cost, energy efficiency, and reliability – exactly the factors that determine whether AI memory scales profitably.

That competitive moat is producing hard numbers. Bernstein analysts, drawing on April export figures from North Chungcheong and Icheon, estimate SK Hynix will generate about $7.5 billion in HBM revenue in the second quarter of 2026, a 25% sequential jump. The forecast is below their earlier $8.2 billion projection, but the direction is unmistakable: HBM remains the core growth engine. Export data showed a 4% month-on-month rise from March and an 81% surge compared with January. Long-term contracts are insulating HBM pricing from the sharper swings seen in conventional memory.

Should investors sell immediately? Or is it worth buying SK Hynix?

The push into end-user devices also gathered pace at the Dell Technologies World 2026 conference, where SK Hynix showcased HBM4 variants, HBM3E, enterprise server memory, and SSDs for AI PCs. The earlier delivery of its PQC21-cSSD, based on 321-layer QLC NAND, positions the company to serve not just data centres but also the growing AI-PC market. First-quarter results already reinforced the financial story: revenue of 52.5763 trillion won and an operating margin of 72%.

But prosperity has bred discontent. The union representing workers at logistics subcontractor P&S Logis is preparing legal action against the memory giant, citing a sharp bonus disparity. Regular employees reportedly received bonuses worth millions of won, while subcontract staff got just 5 million to 6 million won. The union plans to invoke the so-called “Yellow Envelope Act”, which since March allows direct wage negotiations between subcontractors and the parent company, aiming to end what it calls performance-based discrimination.

A more immediate tailwind could come from Samsung Electronics, where a planned 18-day strike begins this Thursday. Analysts expect possible output disruptions, and any shift in customer orders would likely benefit SK Hynix directly. The rivalry for top spot in CEO Score’s ranking of Korea’s largest non-financial firms has already tilted SK Hynix’s way – the memory maker unseated Samsung from first place this year, partly on the strength of its HBM focus.

To meet surging demand, management is doubling down on capacity. A US initial public offering is slated for the second half of 2026, targeting up to $14 billion to fund new plants in South Korea and Indiana. On the product front, first samples of HBM4E are due in the same period, with mass production scheduled for 2027. The combination of record margins, a robust pipeline, and external tailwinds has propelled SK Hynix close to the trillion-dollar club – but the labour dispute and the execution risk of a mega-IPO mean the next chapter will be anything but smooth.
