Samsung Breaks Into Global Elite as AI Memory Demand and Labor Accord Fuel Historic Rally

Samsung Electronics joins the world's top 10 most valuable companies with a $1.56 trillion market cap, fueled by AI memory demand and averted labor strike.

Samsung Electronics capped a remarkable week by settling a potentially disruptive labor dispute and crossing a market-cap threshold that places it among the world's most valuable corporations. The South Korean giant ended Tuesday with a market value of 2,000 trillion won ($1.56 trillion), leapfrogging Meta Platforms to claim the tenth spot on the global rankings. Tesla, in ninth place, sits less than $1 billion ahead.

The stock closed at 360,500 won in Seoul, up 3.3 percent on the day and capping a two-day surge that included a 9.6 percent gain the previous session. The intraday high touched 370,000 won. The rally also lifted the broader KOSPI index to a record close of 8,801.49 points.

AI chip demand powers the engine

The momentum is rooted in the red-hot market for memory used in artificial intelligence data centers. Samsung reported first-quarter revenue of 133.9 trillion won and operating profit of 57.2 trillion won — an eightfold jump from a year earlier. DRAM prices soared between 93 percent and 98 percent over the same period, driven by insatiable demand for high-bandwidth memory.

Samsung’s high-bandwidth memory (HBM) business is now the centerpiece of its growth story. The company has begun shipping samples of industry-first 12-layer HBM4E modules, which deliver 16 gigabits per second and 48 gigabytes of capacity — a 20 percent performance gain over standard HBM4. Capacity for the current year is already fully sold out, and Barclays notes that tight supply could persist through at least 2027.

Nvidia, the dominant designer of AI chips, has confirmed it will use Samsung’s HBM4 memory for its next-generation “Vera Rubin” platform. That endorsement offers a direct path into the highest-growth segment of the AI infrastructure buildout.

Analysts run the numbers

The strong data has prompted a wave of target upgrades. Goldman Sachs lifted its 12-month price target to 480,000 won, citing a structural shift in memory markets. Barclays raised its target for Samsung’s American depositary receipts from $4,250 to $7,300 and maintained an “Overweight” rating. At home, SK Securities set a target of 610,000 won on the local shares.

Not everyone is unabashedly bullish. Jefferies flagged that Korean chip stocks have already exceeded the valuation peaks seen during the dot-com bubble. Still, it sees room to run as long as earnings growth, AI investment, and interest-rate conditions support the rally.

Averting a costly walkout

The backdrop of record profits and surging demand made the threat of labor unrest particularly acute. A planned 18-day strike involving some 48,000 workers was avoided after 74 percent of union members approved a new compensation package. Under the deal, Samsung will set aside 10.5 percent of its semiconductor division’s operating profit for special bonuses paid in shares. One-third of those shares can be sold immediately; the remainder is subject to lock-up periods of one and two years, aligning employee incentives with the stock’s long-term trajectory.

Deepening the Texas bet

Even as the stock hits new highs, Samsung is repositioning its U.S. footprint. The company is moving its American headquarters from Englewood Cliffs, New Jersey, to Plano, Texas, a relocation affecting about 1,000 employees. The shift is more than administrative: Samsung already operates a major fabrication plant in Austin and is building a $37 billion chip factory in Taylor, Texas, where it plans to start 2-nanometer production by 2027. That facility has already secured a $16.5 billion order from Tesla for AI6 processors.

Samsung is also deepening its partnership with Cadence Design Systems to develop software tools for the 2-nanometer node, tackling challenges such as heat density and quantum effects below 3 nanometers.

Broadening the chip story beyond data centers

The company’s memory dominance extends beyond AI. Samsung claims a 40 percent global market share in automotive memory chips, making it the largest supplier in that segment as of 2025. Meanwhile, its sustainability efforts are making headway: despite adding new production capacity in the Device Solutions unit, total greenhouse gas emissions fell year over year. Detailed absolute reductions are due to be published in a sustainability report by the end of June.

The rally carries risk — valuation comparisons to the dot-com era are sobering — but Samsung’s combination of sold-out HBM capacity, a secured Nvidia contract, labor peace, and an expanding U.S. manufacturing base gives investors multiple reasons to stay in the trade. The immediate milestones are clear: completing the Texas office move by year-end and starting real output from the Taylor fab in 2027, when the AI chip fantasy must translate into silicon.
