SK Hynix: Legal Storm Clouds Gather Over a 291% AI Rally
Veröffentlicht: 30.06.2026 um 18:54 Uhr, Redaktion boerse-global.de
SK Hynix has been on a tear, its shares climbing 291% year-to-date to 2,650,000 South Korean won, leaving the stock just 11% below the record high it hit only days ago. The driver is plain: red-hot demand for high-performance memory chips powering artificial intelligence, combined with extremely tight supply. That narrative, however, is now colliding with a US class-action lawsuit that alleges the rally may have been juiced by illegal market manipulation.
The suit, filed in late June in a California federal court, targets SK Hynix, Samsung, and Micron, accusing them of conspiring to artificially restrict supply of conventional DRAM chips. According to the complaint, prices surged roughly 700% over a four-year period as a result. The plaintiffs are seeking the status of a class action and triple damages. Micron has already denied the allegations.
Yet even as the legal threat looms, bulls are doubling down. Barclays last week lifted its price target on SK Hynix to €2,900, implying a potential upside of nearly 90%. The bank cited sustained pricing power in high-performance memory and strong quarterly results from Micron as key catalysts. The move underscores a stark divide: analysts see operational strength, while investors must weigh a budding courtroom drama.
Should investors sell immediately? Or is it worth buying SK Hynix?
To complicate matters, South Korea is planning a massive $518 billion investment blitz by Samsung and SK Hynix into new chip fabrication plants. But SK Group chairman Chey Tae-won is tapping the brakes, asking for more time to secure essential infrastructure such as electricity and water before committing to new sites. The caution hints at a potential supply overhang that could chill the current pricing environment even without a legal ruling.
Supporters of the stock counter that the scarcity at SK Hynix is rooted in genuine customer orders, not collusion. The company is co-developing next-generation memory chips with Nvidia, tailor-made for the US giant's AI roadmap, and has already delivered initial samples of its 12-layer HBM4E chips to key clients. These are premium products, not commodity DRAM, and the tight capacity is a direct response to real demand from AI infrastructure build-outs.
Critics, however, warn that the lawsuit introduces a new layer of uncertainty that the share price has yet to price in. The stock’s volatility already exceeds 100%, and the 52-week low of 491,500 won serves as a stark reminder of how far it can fall. The HBM4E chips are still in testing, with mass production yet to begin — any delays would amplify nervousness. A prolonged legal battle could quickly shift investor focus from technological leadership to legal liability.
The immediate test lies ahead. The 50-day moving average sits near 1.97 million won; a decisive break below that level would signal that the market is beginning to discount the legal risk. In the coming weeks, hard data will matter most: updates from the US court proceedings and management’s next statements on capacity planning will determine whether the bull case of real demand or the bear case of artificial scarcity prevails.
