Samsung and SK Hynix stocks have surged on record AI chip demand, lifting South Korea's KOSPI past 7,000. Discover what's driving the rally and how global investors can gain exposure — including through MEXC's crypto-settled stock futures.
Overview
South Korea's semiconductor giants are having a historic year. Fueled by an artificial intelligence infrastructure boom, Samsung Electronics and SK Hynix have posted record earnings, driven the KOSPI index to all-time highs above 7,000 points, and attracted net foreign inflows of over 6 trillion won in a single month. For investors watching from the sidelines, the central question is: how do I participate?
This article breaks down what is driving the rally, compares the two companies' fundamentals, and outlines several practical ways global retail investors can access exposure — including through MEXC, which offers USDT-settled stock token futures without the need for a traditional brokerage account.
Key Takeaways
On May 6, 2026, Samsung Electronics surged 14.4% and SK Hynix gained 10.6% in a single session, helping push the KOSPI above 7,000 points for the first time in history
High-bandwidth memory (HBM) chips — the core component powering AI accelerators — are the primary driver of both companies' record earnings
Bernstein forecasts continued strong HBM revenue growth for both companies through Q2 2026, supported by April export data showing 62% quarter-on-quarter growth versus January
Samsung and SK Hynix together account for over 51.5% of the KOSPI 200 index by market cap
SK Hynix has filed confidentially with the U.S. SEC for an ADR listing targeting up to $10 billion, which could bring the stock to American exchanges before year-end
Global investors can access exposure through international brokers, Korea-focused ETFs, or crypto-native stock token futures on platforms like MEXC
What Is Driving the Rally
The surge did not happen in a vacuum. SK Hynix had already sold out its entire 2026 production capacity by late 2025, signaling a severe supply-demand imbalance in AI memory. As cloud computing companies accelerated their investments in AI data centers, orders for HBM chips — which power Nvidia GPUs and other AI accelerators — continued to outpace supply.
The immediate trigger for the May breakout was AMD's better-than-expected data center revenue outlook, which sent the Philadelphia Semiconductor Index sharply higher overnight and sparked a rotation into Korean chip names the following morning. According to Reuters reporting on the session, the KOSPI closed up 6.45% at 7,384.56, briefly triggering a rare "sidecar" circuit breaker as the index rose as much as 7.06% intraday. Samsung crossed the $1 trillion market capitalization threshold for the first time, joining TSMC in that exclusive club.
BeInCrypto reported that the EWY South Korea ETF has gained 68% in 2026 and surged 181% over the prior 15 months, making it the top-performing major equity market globally at the time of writing.
Samsung vs. SK Hynix: A Closer Look at the Fundamentals
Samsung Electronics (005930.KS)
Samsung posted record Q1 2026 results: revenue of 133.9 trillion won and operating profit of 57.2 trillion won. The company announced it had become the world's first firm to begin mass production of HBM4 — the sixth generation of high-bandwidth memory — and had started delivering to undisclosed customers.
Samsung's investment case rests on diversification. Beyond memory chips, the company operates a major foundry business, a smartphone division, and a consumer electronics segment. That breadth provides a degree of earnings stability that SK Hynix does not have.
The primary near-term risk is a potential labor stoppage. Seoul Economic Daily reported that Samsung faces its first general strike since its founding, with industry estimates suggesting one day of halted operations could scrap 22,000 wafers and generate losses approaching 650 billion won.
SK Hynix (000660.KS)
SK Hynix has been the standout performer of the two. The company recorded Q1 2026 revenue of 52.5 trillion won, operating profit of 37.6 trillion won, and net profit of 40.3 trillion won — all record highs. Its HBM business is more concentrated than Samsung's, with deep supply agreements with Nvidia and Google providing significant revenue visibility.
In a notable milestone reported by Seoul Economic Daily, SK Hynix's forward price-to-earnings ratio surpassed Samsung's for the first time ever in May 2026. Over the prior three months, SK Hynix's stock rose 78.68% — more than double Samsung's 35.44% gain — as investors assigned a premium to its purer HBM exposure.
On the corporate development front, MEXC reported that SK Hynix has submitted a confidential filing to the U.S. Securities and Exchange Commission for an ADR listing, targeting between $6.7 billion and $10 billion to fund its Yongin HBM production hub and Indiana packaging facility. A successful U.S. listing would significantly broaden the company's investor base.
What Analysts Are Saying
Institutional views are broadly constructive, though increasingly nuanced.
Bernstein, citing Korea's April semiconductor export data, highlighted that multichip memory exports to Taiwan and Malaysia came in at $3.7 billion for the month — down 12% from March on seasonality but up 62% compared to January — signaling solid underlying demand for Q2 2026. The analyst firm expects HBM prices to be reset higher in early 2027, a development that could favor SK Hynix given its larger share of contracts.
Goldman Sachs raised its year-end 2026 KOSPI target to 7,000 and upgraded its Korea earnings-growth forecast to 130%, citing stronger semiconductor conditions. That target has since been surpassed. JP Morgan analyst Mixo Das wrote that the supply-demand gap for memory chips is expected to widen further into 2027, with customers already pulling orders forward in anticipation of future shortages.
The bull case, as EBC Financial Group summarized, is not simply that AI is popular — it is that AI spending is driving a real earnings upcycle for Korean chip companies, with share prices rising because future profits are rising too.
How to Trade the Rally: Options for Global Investors
Samsung and SK Hynix are listed on the Korea Exchange (KRX) under tickers 005930.KS and 000660.KS respectively. For most international retail investors, direct access requires opening an account with a broker that supports KRX trading. Here are the main routes:
Option 1: International brokers with KRX access
Several global brokerage platforms offer access to South Korean equities. This typically involves completing account registration and identity verification, depositing funds, and converting to Korean won where required. This route provides direct equity ownership but can involve currency conversion costs and administrative friction.
Option 2: Korea-focused ETFs
For investors who prefer to stay within familiar markets, the iShares MSCI South Korea ETF (EWY) trades on U.S. exchanges and carries significant Samsung and SK Hynix exposure. JustETF data shows SK Hynix is currently held across 179 ETFs globally, with the Xtrackers MSCI Korea UCITS ETF carrying the highest weighting. ETFs are generally the lowest-friction path for investors who do not need single-stock exposure.
Option 3: Crypto-native stock token futures on MEXC
For investors already operating within the crypto ecosystem, MEXC offers USDT-settled stock token futures that provide exposure to equity price movements without the need for a traditional brokerage account. Contracts support both long and short positions, trading hours align with official market sessions, and real-time price feeds are sourced from official providers.
Finance Magnates reported that MEXC's Stock Futures product includes up to 5x leverage on new pairs, a dedicated Futures Insurance Fund, and a risk control system designed to manage market instability. On May 6 — the day of KOSPI's historic 7,000 breakout — MEXC reported that DRAM-linked stock token futures on the platform recorded approximately $30.13 million in combined 24-hour turnover, reflecting a meaningful spike in trader interest.
Risks Worth Watching
Despite the strong fundamentals, several factors could disrupt the current momentum:
Concentration risk: Samsung and SK Hynix together account for over 51% of the KOSPI 200 index. Any significant correction in either stock would have outsized implications for the broader Korean market.
Labor dispute at Samsung: The looming threat of Samsung's first-ever general strike introduces near-term supply chain uncertainty. South Korea's Prime Minister noted that a single day of halted operations could cost close to 1 trillion won in losses.
Valuation stretch: Both stocks have gained more than 70% within six months. Analysts such as those at EBC Financial Group caution that chip demand expectations may already be priced aggressively into current valuations.
Currency exposure: International investors holding non-won assets are subject to Korean won fluctuations, which can affect realized returns regardless of stock performance.
Regulatory and tariff risk: Potential U.S. tariffs on imported chips and evolving semiconductor export controls remain background risks for both companies' global supply chains.
MEXC Crypto Pulse Research Team: Exclusive Perspective
The Samsung and SK Hynix rally is, at its core, a story about the scarcity of AI infrastructure components. When Nvidia GPUs became the most sought-after asset in the world, it was only a matter of time before the companies supplying the HBM memory inside those chips received a commensurate revaluation. The market arrived at that conclusion in 2026.
For crypto investors, this carries a specific implication. Historically, crypto market cycles have shown positive correlation with risk-on environments driven by tech sector outperformance. A confirmed semiconductor supercycle — with earnings revisions still trending upward — is typically a constructive backdrop for digital assets as well. The fact that platforms like MEXC now allow users to trade Samsung-adjacent equity exposure through crypto-settled derivatives is itself a structural development worth noting: the boundary between TradFi and crypto continues to narrow.
Our view is that as long as AI capital expenditure does not show systematic signs of contraction, the earnings upgrade cycle for HBM suppliers is likely to extend into 2027. SK Hynix's potential U.S. ADR listing, if executed successfully, represents a meaningful additional catalyst. In the near term, the Samsung labor negotiations and any developments on U.S. chip tariff policy deserve close monitoring.
FAQ
Q1: Can I trade Samsung or SK Hynix directly on MEXC?
MEXC offers USDT-settled stock token futures that allow users to take long or short positions on equity-linked instruments without opening a traditional brokerage account. This is structurally closer to a crypto-settled derivative than direct equity ownership. Leverage amplifies both gains and losses, and positions can be liquidated if margin requirements are not met.
Q2: What is HBM and why does it matter so much?
High-bandwidth memory (HBM) is a specialized DRAM technology designed for AI accelerators and high-performance computing. Unlike conventional DDR memory, HBM stacks multiple memory dies vertically and integrates them closely with the processor, achieving far higher data throughput. Nvidia's H100 and H200 GPUs, which power most commercial AI training workloads, rely on HBM as their primary memory solution.
Q3: When could SK Hynix start trading as a U.S. ADR?
SK Hynix has submitted a confidential SEC filing targeting completion by the end of 2026, according to MEXC's reporting. However, the offering size, pricing, and exact timeline have not been finalized, so the schedule remains subject to change.
Q4: Which ETF gives the most direct exposure to the Korea semiconductor rally?
The iShares MSCI South Korea ETF (EWY) is the most liquid Korea-focused ETF available on U.S. exchanges and carries significant Samsung and SK Hynix exposure. Investors seeking a more focused semiconductor allocation may also consider broad semiconductor ETFs such as SOXX, though these carry a U.S.-heavy tilt.
Q5: Is the rally sustainable?
The structural case for AI memory demand running through 2027 is supported by Bernstein, Goldman Sachs, and JP Morgan. However, both stocks have moved sharply in a short period, and near-term catalysts — including the Samsung labor situation and macro factors like Federal Reserve policy and the strength of the Korean won — warrant close attention.
Q6: How do Samsung and SK Hynix compare as investment cases?
Samsung offers broader diversification across memory, foundry, mobile, and consumer electronics. SK Hynix provides more concentrated exposure to the HBM growth story and has delivered superior stock performance in this cycle, though its earnings are more sensitive to memory pricing cycles. Wall Street analysts have assigned Buy ratings to both, with a marginal consensus advantage for SK Hynix based on Q1 2026 results.
