AI Memory Era: Supply Chain Reshaping Intensifies
The advent of the artificial intelligence (AI) era is fundamentally altering the global semiconductor landscape, driven by an explosive surge in High Bandwidth Memory (HBM) demand. TrendForce projects HBM’s share of total DRAM wafer input to grow from approximately 18% at the end of 2025 to 22% in 2026 and 30% in 2027. The global HBM market size is expected to reach $3.98 billion in 2026 and surge to $12.44 billion by 2031, reflecting a compound annual growth rate (CAGR) of 25.58% over the period. Amid this immense demand, U.S. chipmaker Micron Technology has announced a strategic shift, increasing its planned U.S. investment for AI memory production to over $250 billion through 2035.
U.S. Dominance Strategy and Corporate Maneuvers
Micron’s expanded commitment, a $50 billion increase from its previous $200 billion plan, directly addresses the escalating demand for AI memory. The company aims to produce 40% of its DRAM in the United States over the long term. Demonstrating rapid progress, Micron celebrated the first concrete pour at its Clay, New York site ahead of schedule, marking the transition to vertical construction. This facility is poised to become the largest private manufacturing project in New York’s history and potentially the largest semiconductor manufacturing site in the U.S. Furthermore, Micron has pledged up to $3 billion to bolster the domestic semiconductor supply chain, including a $500 million strategic investment in GlobalWafers’ Texas facility.
The U.S. government is exerting significant pressure. Commerce Secretary Howard Lutnick is actively urging major memory chip manufacturers, including Samsung Electronics and SK Hynix, to expand their production capacity on American soil. In January 2026, Secretary Lutnick reportedly delivered a stark ultimatum: companies must either build in America or face a 100% tariff on chips sold into the U.S. market. This aggressive stance is part of a broader U.S. strategy, enabled by the CHIPS and Science Act, to enhance domestic semiconductor manufacturing capabilities and supply chain resilience. The U.S. aims to produce 20% of the world’s leading-edge logic chips by 2030, a significant jump from current levels. CHIPS Act funding is being prioritized for projects expected to be completed by 2030 to maximize impact within this decade.
HBM Market: Intense Competition Among Key Players
The High Bandwidth Memory (HBM) market remains highly concentrated, with SK Hynix, Samsung Electronics, and Micron controlling over 95% of global output. SK Hynix is projected to maintain a dominant market share exceeding 60% in 2026, driven by its early adoption and successful deployment of HBM3E and HBM4 technologies. Samsung is aggressively working to narrow the gap, securing significant HBM4 supply agreements. As of Q1 2026, Micron and Samsung each held a 21% market share, trailing SK Hynix’s 58%.
Despite HBM’s per-wafer profitability dipping below that of conventional DRAM in Q1 2026, the relentless demand from AI accelerators continues to strain HBM supply, signaling a sharp increase in HBM contract prices in 2027. These market dynamics underscore the critical importance of each company’s production strategy and governmental support. A key factor to watch is the Advanced Manufacturing Investment Credit, a vital incentive under the CHIPS Act, which is set to expire on December 31, 2026. Its extension will be crucial for future investment decisions.
Market Outlook and Investor Implications
The structural transformation of the semiconductor industry demands a long-term perspective. AI memory demand will persist well beyond 2027, necessitating continuous capital expenditure and technological innovation from key players. Investors should closely monitor the progress of U.S. manufacturing facilities, particularly large-scale projects like Micron’s New York fab. Furthermore, changes in U.S. government policy, especially the extension of the critical Advanced Manufacturing Investment Credit under the CHIPS Act, will significantly shape the investment landscape. Ongoing analysis of market share shifts and technology roadmaps among SK Hynix, Samsung, and Micron in the HBM segment is essential. The trend toward supply chain diversification and localization will introduce both new opportunities and risks, requiring a sophisticated understanding of strategic implications.
