Samsung’s Multifront AI Push: HBM4E Samples Ship, Automotive Memory Share Hits 40%, and Wearables Get a Health Overhaul

Samsung ships 12-layer HBM4E samples, unveils HBM5 for Nvidia, leads automotive memory at 40%, posts record profit. Goldman raises price target.

Samsung Electronics has entered June with a flurry of announcements spanning its most critical business lines. The conglomerate shipped first samples of its 12-layer HBM4E memory to key customers on June 3, unveiled an HBM5 prototype at Computex the day before, and now commands a 40 percent global market share in automotive memory chips — up from 35 percent a year earlier. The moves underscore a concerted effort to reclaim ground in premium AI memory and extend dominance in fast-growing automotive storage.

The HBM4E samples represent a direct challenge to SK Hynix, which controlled 57 percent of the high-bandwidth memory market in the fourth quarter of 2025. Samsung held just 22 percent in that period, with Micron at 21 percent. If Samsung’s latest generation passes customer qualification, its massive manufacturing capacity could rapidly reshape the competitive landscape. Further out, the company demonstrated an HBM5 prototype targeting a bandwidth of 4 terabytes per second — double that of HBM4E — with mass production not expected before 2028 to 2029. The chip is designed for Nvidia’s future “Feynman” architecture, two generations beyond the upcoming Vera Rubin platform.

On the automotive front, Samsung has overtaken Micron in memory chips for vehicles. Its 40 percent share compares with 36 percent for Micron, which dropped from 40 percent in 2024. The shift is being driven by rising demand for high-capacity storage in autonomous driving systems and infotainment, with Samsung’s low-power DRAM and Universal Flash Storage especially well positioned. In the broader DRAM market, Samsung remains the leader with 38 percent market share in the first quarter of 2026, within a total quarterly market that has grown to $97 billion.

The stock’s fundamentals have kept pace with the strategic momentum. Samsung posted an operating profit of 57.2 trillion won in the first quarter of 2026 — more than eight times the year-ago figure and already eclipsing full-year 2025 profit. Revenue hit a record 133.9 trillion won. Goldman Sachs raised its price target to 480,000 KRW in early June, arguing that the memory sector is structurally shifting away from a highly cyclical commodity market toward a more predictable AI infrastructure model, warranting a valuation move from price-to-book to price-to-earnings.

Samsung’s foundry ambitions also got a notable boost. In a recent fundraising round that valued the AI company at roughly a trillion dollars, Anthropic named Samsung as a strategic infrastructure partner — specifically highlighting the Korean giant’s logic-chip capabilities. That distinction sets Samsung apart from other partners like Micron and SK Hynix and could open the door to further foundry contracts, following last year’s multibillion-dollar supply deal with Tesla.

The company’s AI offensive extends beyond chips and into consumer devices. Starting June 8, Samsung will roll out a major update to its Health app with four AI-powered features — Vitals, Heart Health Score, Daily Cardio Load and Fitness Index — organized into five core areas: sleep, activity, nutrition, mindfulness and vital signs. The Vitals feature analyzes five biometric signals upon waking, while the Heart Health Score blends sleep, stress, activity and body composition into a single daily metric. Full functionality will debut with the next-generation Galaxy Watch models, expected to include the Watch 9, Watch 9 Classic and Watch Ultra 2, likely announced at an upcoming Galaxy Unpacked event.

Not everything is running smoothly internally. Labor tensions have surfaced after a wage agreement in May tied a performance bonus worth 10.5 percent of semiconductor division operating profit to chip employees only, excluding workers in the device business. Reports indicate that non-semiconductor staff are leaving the main union in favor of alternative organizations, which could complicate future collective bargaining.

After a seven-day rally of more than 17 percent, Samsung’s stock sits roughly 5 percent below its 52-week high of 370,000 KRW. The shares have more than tripled over the past year. With the relative strength index at 73, technical indicators point to overbought conditions — a consolidation of around 2.5 percent, as seen recently, is not surprising. The near-term catalyst remains the qualification of the HBM4E chips: if successful, Samsung would not only solidify its partnership with Anthropic but also reemerge as a serious contender in the most lucrative memory segment of the AI era.
