A Seoul trading floor erupted on October 28, 2026, as ticker screens flashed a staggering 632% profit surge for memory chipmaker SK Hynix. The South Korean supplier's earnings blowout shows how heavily the global AI boom depends on its hardware, with ripple effects heading straight toward consumer tech prices.
What happened: Record earnings and a massive payout
On October 28, 2026, SK Hynix posted quarterly revenue of 104.62 trillion won (about $78.86 billion USD) and record operating profits of 83.33 trillion won ($62.8 billion USD). US-listed depositary receipts jumped 13.3% during the day, while Seoul-listed shares rose over 10% following the announcement.
Executive leadership attributes the record performance to skyrocketing demand for High Bandwidth Memory (HBM) and general memory chips. Management also announced a 100 trillion won shareholder return program for 2026, while CEO Kwak Noh-Jung confirmed the halt of an IPO review for US subsidiary Solidigm due to market volatility.
Is it true: Does SK Hynix control the AI chip race?
The evidence supports the claim that SK Hynix's dominance is steering the AI chip sector. The company was the first to mass-produce HBM3 and HBM3E chips, establishing an early lead in high-performance memory.
SK Hynix serves as the sole HBM3E supplier for Microsoft’s Maia 200 AI accelerator while anchoring supply for NVIDIA’s Blackwell and Hopper chips. Goldman Sachs forecasts that SK Hynix will maintain over 50% market share in HBM memory chips through at least 2026.
| Metric | Q3 2026 Performance | Key Context |
|---|---|---|
| HBM Revenue Share | 30% of DRAM sales | Projected to reach 40% in Q4 |
| HBM QoQ Sales Growth | Over +70% | +330% year-over-year jump |
| Average Selling Prices | Mid-10% to late 20s% QoQ boost | Broad gains across DRAM and NAND |
Why it matters: Tech hardware budgets and AI stock bets
Memory chip supply constraints directly influence the cost of electronic devices. SK Hynix announced that its DRAM and HBM production capacity is completely booked through 2029, with structural supply deficits expected to persist until 2030. Because memory chips are essential components in cloud servers, personal computers, and smartphones, potential memory shortages could influence the pricing and availability of tech products.
Wall Street analysts from Morgan Stanley, Citigroup, and Wedbush raised their stock outlooks following the news. However, experts at Acadian Asset Management warned that US depositary receipts trading at a 50% premium over Seoul-listed shares could reflect temporary overheating in AI trading.
What to watch next: Next-gen memory and expanded factories
SK Hynix is shifting focus toward its next-generation HBM4 chips, expecting them to eclipse HBM3E in shipment volume and revenue share. The company is also advancing a 16-layer HBM3E design with 48GB capacity aimed at a 2025 release window.
Long-term supply agreements already lock in over 50% of total production capacity through 2028 across 14 major hyperscale clients. The company's M15X manufacturing facility is scheduled to reach full operational output by the end of 2026 as negotiations for 2027 supply contracts conclude.
