Weekly Supply Chain in Asia 2026-W23 (2026-05-28~2026-06-03)

The relentless demand for artificial intelligence infrastructure is fundamentally reshaping global supply chains, creating a dynamic landscape of intense competition and strategic opportunities for East Asian companies. This week, the sheer scale of AI’s influence was palpable, from SoftBank Group’s colossal EUR 75 billion investment in French data centers to Nvidia’s deepening “K-Alliance” in South Korea, extending beyond semiconductors into robotics and cloud ecosystems. Meanwhile, the semiconductor sector itself remains a focal point, with Samsung Electronics pushing the boundaries of AI memory with its HBM4E samples and TSMC’s aggressive pricing strategies creating openings for rivals. These developments underscore a broader trend: East Asian firms are not just responding to market shifts but actively driving them, whether by challenging established automotive players, securing footholds in crucial energy markets, or pioneering new manufacturing techniques. Geopolitical currents and policy shifts continue to influence these dynamics, favoring resilience and strategic partnerships over pure cost optimization.

This Week’s Events

The insatiable appetite for AI infrastructure is driving unprecedented investment and technological advancement across East Asia. SoftBank Group announced a staggering EUR 75 billion (approximately JPY 14 trillion) commitment to develop 5 gigawatt (GW) of AI data center capacity in France, marking its largest AI infrastructure investment in Europe and signaling a significant expansion of global AI hardware deployment. This move, alongside Nvidia CEO Jensen Huang’s strategic expansion of its “K-Alliance” in South Korea, highlights the critical role of AI hardware and supporting ecosystems. Nvidia is now collaborating with Korean partners like Naver Cloud for LLMs and AI factories, and Doosan Robotics for physical AI solutions, extending its influence beyond semiconductors into robotics and cloud services.

This surge in AI demand directly fuels the semiconductor sector’s strategic plays. Samsung Electronics has further solidified its leadership in AI memory by commencing sample shipments for its HBM4E 12-layer product, boasting 16Gbps per-pin speed and 3.6 TB/s bandwidth, intensifying competition with rivals like SK Hynix. Simultaneously, TSMC’s planned price hikes for its advanced 3nm process by up to 15% in the second half of 2026 are creating a strategic opening for Samsung Electronics in the foundry market. Big tech firms are increasingly seeking supply chain diversification, potentially benefiting Samsung’s competitive pricing and 3nm Gate-All-Around (GAA) process. The broader market sentiment reflects this semiconductor strength, as South Korea’s weight in the MSCI Emerging Markets Index rose to 21.60%, surpassing China’s 21.38% and driven by the surging stock prices of key players like TSMC, Samsung Electronics, and SK Hynix.

The ripple effects of AI demand are reshaping other critical supply chains. Korean copper foil makers are accelerating a strategic pivot towards high-value products for AI infrastructure and advanced electronics, shifting focus away from the increasingly volatile EV battery market. SK Nexilis saw its ESS copper foil sales surpass EV copper foil sales in Q1 2026, projecting ESS products to comprise nearly half of its sales by H2 2026. Lotte Energy Materials is focusing on circuit foil (CCL) for data centers, a segment benefiting from AI server expansion, while Solus Advanced Materials is realigning its strategy following the sale of its Luxembourg subsidiary. This strategic realignment allows these companies to capitalize on higher-margin opportunities.

In the automotive sector, Chinese brands, led by BYD, have achieved a significant milestone by surpassing Japanese automakers in South Korea’s imported car market for the first time in April 2026, securing a 6.0% market share against Japan’s 5.8%. BYD’s strong EV sales, supported by subsidies, and the recognition of Chinese brands’ advancements in software-defined vehicle (SDV) technology, are key drivers. This shift, coupled with the withdrawal of some Japanese brands, signals a restructuring of regional supply partnerships and distribution networks.

The energy transition continues to evolve, with distinct regional dynamics. The rechargeable battery industry is entering a new phase, with robust EV sales growth in Europe, bolstered by regulations and subsidies like the Industrial Acceleration Act, expected to benefit Korean battery firms. In contrast, US EV sales are projected to contract by approximately 30% year-over-year, though inventory adjustments are nearing completion. However, US Energy Storage System (ESS) installations are showing strong year-to-date growth of 72%, indicating a significant pivot towards grid-scale storage solutions. Meanwhile, Korean solar firms are gaining ground in the US market, benefiting from policy shifts that favor excluding Chinese supply chains. Hanwha Solutions is expanding its US domestic production to 3.3 GW by H2 2026, aiming for AMPC benefits, while OCI Holdings, with its Malaysian polysilicon production, is positioned to compete against potential tariffs on Chinese polysilicon. The US solar market’s growth is further fueled by surging power demand from AI data centers.

In policy and emerging tech, Japan is taking proactive steps to bolster its cybersecurity defenses by acquiring access rights to OpenAI’s new AI model, “GPT5.5 Cyber.” The Japanese government and major financial institutions, including MUFG, SMBC, and Mizuho, will leverage this technology to counter AI-driven cyber threats, signaling a strategic integration of advanced AI into national security infrastructure.

Samsung Electronics also marked a significant corporate milestone, reaching a market capitalization of approximately USD 1.171 trillion by May 6, 2026. This achievement positioned it as the second Asian company, after TSMC, to join the “Trillion Club,” underscoring its transformation into a global tech powerhouse and its profound influence on the semiconductor and electronics industries.

Looking Ahead

The relentless pursuit of AI dominance and the resulting supply chain realignments will continue to be the dominant narrative. Key areas to watch in the coming weeks include:

  • AI Memory Competition: Further developments in the technological race between Samsung Electronics and SK Hynix in next-generation AI memory, particularly HBM4E and beyond, will be critical for market share and performance.
  • Foundry Market Dynamics: The impact of TSMC’s advanced foundry pricing strategy on Samsung Electronics’ ability to capture market share and achieve profitability in its foundry business will be closely monitored.
  • Nvidia’s Korean Ecosystem Expansion: The concrete outcomes and specific joint development projects emerging from Nvidia’s expanded “K-Alliance” in South Korea, particularly in robotics and cloud services, will shape the future of physical AI applications.
  • US Solar Market Trajectory: The progress of Korean solar firms like Hanwha Solutions and OCI Holdings in the US market, especially in light of potential Section 232 investigation results and the ongoing demand from AI data centers, will reveal shifts in global solar supply chains.

The week’s events underscore a period of significant strategic repositioning across East Asia’s industrial landscape, driven by technological innovation and evolving global demand.
