A week that saw SK Hynix’s market valuation briefly surpass $900 billion has also laid bare the two-pronged strategy the memory giant is pursuing to lock in its dominance: tapping sovereign wealth from the Gulf while simultaneously moving to reduce its reliance on TSMC’s bottlenecked packaging technology.
The stock hit an intraday record of 1,949,000 Won on Monday, surging 11.51 percent to close at 1,880,000 Won before retreating 2.13 percent the following session to 1,840,000 Won. That still leaves the shares up 171.79 percent since the start of 2026. The rally has been fuelled by a perfect storm of unprecedented demand for high-bandwidth memory (HBM) and a supply chain so tight that SK Hynix has declared its DRAM, NAND and HBM capacity effectively sold out for the rest of the year.
The figures behind the frenzy are staggering. In the first quarter of 2026, SK Hynix posted record revenue of 52.6 trillion Won, a 198 percent jump year-on-year. Operating profit came in at 37.61 trillion Won, yielding a jaw-dropping operating margin of 72 percent. The company ended the period with a net cash position of 35 trillion Won, liquid assets of 54.3 trillion Won, and debt of just 19.3 trillion Won, giving it a leverage ratio of 12 percent.
That financial muscle is coming in handy as SK Hynix pursues two parallel paths to secure its future. On the demand side, a high-level delegation from the United Arab Emirates — including representatives of sovereign wealth giants ADIA and Mubadala — is set to visit the company’s chip facilities on May 12. The visit is far from ceremonial. The UAE is building a Stargate AI campus with a planned capacity of 5 gigawatts and wants a direct pipeline to the HBM memory that powers the largest AI data centres.
The following day, the Korea-UAE Forum on AI Infrastructure and Semiconductors opens in Seoul, with early agreements already in place for SK Hynix to supply HBM for data centres linked to OpenAI. Long-term supply commitments and potential joint investments in additional capacity are expected to be on the table as the Emirates seeks to insulate itself from the wild swings of spot memory markets.
Should investors sell immediately? Or is it worth buying SK Hynix?
On the supply side, SK Hynix is working to reduce a different kind of vulnerability. According to a ZDNet Korea report, the company is testing Intel’s EMIB (embedded multi-die interconnect bridge) technology as an alternative to TSMC’s CoWoS packaging process, which has become a notorious bottleneck for AI accelerators. EMIB uses tiny silicon bridges embedded in the substrate rather than a large interposer, and TrendForce estimates the yield at Intel’s EMIB substrates had reached as high as 90 percent by April 2026. That makes the technology a credible backup, even though the smaller bridge area can introduce latency and bandwidth limitations that may suit ASIC customers better than GPU giants demanding maximum throughput.
SK Hynix is also investing heavily in its own packaging capabilities. A new advanced packaging facility in West Lafayette, Indiana, is slated to begin operations in 2028, while the company approved another large plant in Cheongju, South Korea, in January for packaging and testing. A small domestic research line for 2.5D packaging is already running, aimed at aligning future HBM generations more closely with downstream packaging structures.
The urgency of these efforts is underscored by the competitive threat from Samsung. According to SBS Biz, Samsung has passed final quality tests for HBM4 with both Nvidia and AMD, with first deliveries expected in June. Samsung is also said to have raised prices significantly on the 4-nanometer logic chips used in HBM4. If Samsung ramps successfully, SK Hynix’s market share could slip from its current dominance to 50–60 percent.
Analyst targets reflect the high expectations yet divergent views on how long the cycle will last. Citigroup lifted its price target to nearly 3.1 million Won, betting on rising memory prices through the second half of 2026. UBS raised its target to 1.7 million Won on May 11, flagging an exceptionally strong memory cycle, while Goldman Sachs pegged the DRAM supply deficit for the full year at 4.9 percent.
The next milestones are already set: the Seoul forum on May 13 could yield concrete investment and supply pacts with the UAE, while Samsung’s HBM4 launch in June will test whether SK Hynix’s technological lead — and its Intel packaging hedge — can hold. For now, the memory maker is playing both offence and defence, and the market is pricing in every move.
