Overview
Samsung Electronics is a South Korean multinational and one of the world’s largest semiconductor manufacturers. Together with SK Hynix, Samsung accounts for roughly 70% of global DRAM supply and a commanding share of high-bandwidth memory (HBM) used in AI accelerators.
Key Facts
- Together with SK Hynix, accounts for ~70% of global DRAM and a major share of HBM production Helium Crisis Tightens Grip On Global Chip Supply Chain
- South Korea imported ~64.7% of its helium from Qatar in 2025, creating acute supply vulnerability Helium Crisis Tightens Grip On Global Chip Supply Chain
- Deployed industry-first Helium Reuse System (HeRS) to recover, purify, and reuse high-purity exhaust helium Helium Crisis Tightens Grip On Global Chip Supply Chain
- Memory fabrication is particularly helium-intensive due to repeated high-heat etching and deposition steps for 3D stacking
- Signed non-binding LOI with OpenAI (Oct 1, 2025) for massive DRAM wafer supply, unaware of parallel SK Hynix deal. Combined deals consumed ~40% of global DRAM output Sam Altman’s Dirty DRAM Deal
- Q1 2026 earnings: 57.2 trillion won ($37.92B) operating profit — 8.5x YoY (from 6.69T won). Nearly triples previous record (20T won, Q4 2025). Chip division: 54T won (95% of total). Revenue: 133T won (+68% YoY). Beat analyst consensus by 41%. Samsung Flags Eightfold Jump in Q1 Profit — Reuters
- Ramped HBM production toward 250K wafers/month (47% capacity increase) in response to OpenAI LOIs; later shifted 80K wafers back to DDR5 RDIMM after demand collapsed The Letter That Moved a Market — Medium Samsung HBM DDR5 DRAM Capacity Shift — Digitimes
- Q3 2025 global DRAM market share: 32.6% ($13.5B revenue, +30.4% QoQ) — second to SK Hynix (33.2%) TrendForce DRAM Market Share Q3 2025
- Now Apple’s largest DRAM supplier, accounting for 60-70% of iPhone 17 series shipments Apple Executives Booking Extended Hotel Stays for DRAM LTA — WCCFTech
- Strike threat (May 2026): 90,000 unionized workers voting on 18-day strike from May 21, 2026; could halt ~50% of Pyeongtaek semiconductor production. Pay gap with SK Hynix is primary grievance. Workers seeking 7% base wage increase + profit-sharing. Samsung workers’ strike plan would disrupt chip supply
- Signed MOU with AMD (Mar 18, 2026) for HBM4 supply for MI455X GPU + DDR5 for EPYC Venice CPUs. Lisa Su visited Pyeongtaek and met with Vice Chairman Lee Jae-yong. Samsung and AMD Expand Strategic Collaboration — Press Release
- Tesla actively poaching Samsung chip designers Samsung workers’ strike plan would disrupt chip supply
Newsletter Relevance
Samsung’s dominance in memory chips places it at the center of several newsletter themes: Infrastructure Warfare (helium supply disruptions cascade into AI chip production), Chokepoint Control (concentration of critical manufacturing), and the AI buildout (HBM is the gating component for AI accelerators).

Open Questions
- Did Samsung build strategic helium reserves after the four previous helium crunches (since 2006)?
- What is Samsung’s actual HBM production timeline exposure if Qatar helium remains offline beyond six months?
- How does Samsung prioritize between AI memory and consumer DRAM if forced to ration helium?
