Samsung Electronics shares climbed 5.4% to a record 190,900 won on Thursday after South Korean newspaper Chosun Ilbo reported that the company is negotiating HBM4 chip prices at approximately $700 per unit, representing a 20% to 30% premium over the previous HBM3E generation. The pricing report landed after markets reopened from a three-day Lunar New Year holiday, and the gap-up reflected accumulated conviction that Samsung’s HBM4 leadership is translating into pricing power that could reshape the company’s earnings trajectory for the full year.
The $700 price point has significant implications for the competitive landscape. SK Hynix had previously locked in HBM4 pricing for Nvidia in the mid-$500s per unit, reflecting the negotiated terms from when SK Hynix was the undisputed HBM leader. Samsung’s ability to command a 30% premium suggests that its first-mover status in HBM4 mass production has given it leverage that was absent in the HBM3E generation. Chosun Ilbo reported that SK Hynix may now look to raise its own pricing to match Samsung, a dynamic that would benefit both producers simultaneously and extend the margin expansion cycle across the entire Korean memory sector.
Saxo Markets chief investment strategist Charu Chanana described the pricing report as a sign that “the AI memory market is still tight, and that Samsung believes it has regained some pricing leverage at the premium end.” The characterization captures the broader market narrative: the supply constraint that has defined the HBM market since 2024 shows no signs of easing, and each incremental data point on pricing, qualification, and shipment volumes reinforces the view that Korean memory producers are operating in an extraordinarily favorable environment.
SK Hynix shares gained 1.59% on the same session, a modest but positive reaction that indicates the market views Samsung’s pricing power as a sector-wide positive rather than a zero-sum competitive loss. The logic is straightforward: if Samsung can charge $700, SK Hynix can charge more than mid-$500s when its own HBM4 production ramps in the second quarter. The rising-tide dynamic is a characteristic of tight supply environments and is the primary reason that memory stocks tend to outperform in the early and middle stages of upcycles. The risk of margin compression arrives later, when capacity additions begin to exceed demand growth, a scenario that the industry’s capex trajectory suggests is unlikely before 2028.
The KOSPI has now risen approximately 34% year-to-date, making it the world’s best-performing major equity market in 2026. Samsung and SK Hynix have driven a disproportionate share of the advance, but the governance reform premium has broadened the rally to include holding companies, financial firms, and consumer names. The index is approaching the 6,000 level that seemed improbable at the start of the year but now appears achievable if semiconductor earnings continue to exceed expectations. The parallel with Japan’s governance-driven rerating remains the dominant analytical framework for international allocators evaluating the Korean market.
For portfolio managers, the pricing report introduces a new variable into Samsung’s valuation model. At $700 per unit with 50-60% operating margins, HBM4 becomes one of the highest-margin product categories in the semiconductor industry. The question is volume: how many units can Samsung ship at this price, and for how long can the pricing premium persist before competitive dynamics and customer pushback compress margins. The current setup favors Samsung strongly, but the speed of the valuation advance, from approximately 128,000 won at the start of the year to 190,900 won in seven weeks, means that future expectations are being capitalized into the stock price at a pace that leaves limited room
