September 2026 Chip Market Panorama: AI and Automotive Chips Lead the Charge, Memory Chips Face Structural Inflection Point
In September 2026, the global semiconductor market exhibited a clear trend of price divergence. According to the latest market data, AI chips and automotive chips continued to lead price increases, while memory chips entered a critical inflection point, showing structural changes in price trends. This trend not only reflects profound shifts in downstream application demands but also signals that the semiconductor industry is undergoing a new cycle of supply and demand restructuring.
AI Chip Prices Continue to Climb, Driven by Surging Computing Power Demand
Fueled by the wave of artificial intelligence technology, high-performance AI chip prices maintained an upward trajectory in September 2026. Market research indicates that the price of high-end training chips has risen by 15%-20% compared to the beginning of the year, and the price increase for inference chips reached 8%-12%. This phenomenon is primarily due to the continuous expansion of AI large model parameters and the explosive growth of edge AI applications.
From the supply side, the manufacturing of AI chips heavily relies on advanced process technologies, and the advanced capacity of foundries like TSMC and Samsung is nearing full utilization. In particular, supply tightness in processes of 3nm and below has led to general lead times for AI chips extending to 20-26 weeks, which is over 30% higher than for conventional chips. This supply-demand imbalance directly drives the rise in AI chip prices.
Analyzing the demand side, large technology companies show diversified needs for AI chips. On one hand, tech giants such as OpenAI and Google are continuously scaling up AI model sizes, maintaining strong demand for training chips. On the other hand, companies like Meta and Amazon are accelerating the deployment of edge AI applications, driving rapid growth in inference chip demand. This dual demand structure results in the AI chip market presenting a situation of "scarcity in high-end, tightness in mid-range."
Automotive Chip Prices Lead, Driven by Dual Forces of Intelligence and Electrification
In September 2026, automotive chip prices continued their upward trend since the beginning of the year, with the most significant increases seen in High-Performance Computing (HPC) chips, image sensors, and Power Management ICs (PMICs). Market data shows that automotive-grade HPC chip prices rose by 22% year-on-year, automotive-grade image sensor prices rose by 18%, and PMIC chip prices rose by 15%.
Behind the rise in automotive chip prices is the dual driving force of intelligentization and electrification in the automotive industry. With the proliferation of Advanced Driver Assistance Systems (ADAS) and autonomous driving technologies, the chip consumption per vehicle continues to climb. The computing power demand for AI chips in high-end models has increased from approximately 10 TOPS in 2020 to 200-500 TOPS currently, a growth of 20 to 50 times. Simultaneously, the demand for power chips such as IGBTs and MOSFETs from electric vehicles has significantly increased, with a high-end electric vehicle requiring 3 to 4 times the quantity of power chips compared to a traditional gasoline car.
From a supply chain perspective, the shortage of automotive chips is unlikely to ease in the short term. On one hand, 8-inch wafer capacity is mainly used to produce automotive chips, but the global expansion of 8-inch wafer fabs is slow, with an annual capacity growth rate of only about 5%, far below the growth rate of demand. On the other hand, automotive chips have extremely high requirements for reliability and consistency, leading to long certification cycles and slow release of new capacity. This supply-demand contradiction cannot be resolved in the short term, and automotive chip prices are expected to remain high in the fourth quarter of 2026.Storage Chips Hit Structural Inflection Point, Price Trends Show Clear Divergence
In sharp contrast to the continuous rise in AI and automotive chips, the memory chip market experienced a critical turning point in September 2026. DRAM contract prices stabilized for the first time after two consecutive quarters of decline, while NAND flash prices saw their first quarterly increase since 2022. This structural shift indicates that the memory chip market is transitioning from oversupply to supply-demand balance.
The stabilization of DRAM prices is mainly attributable to three factors: First, PC and smartphone market inventories have decreased to healthy levels, leading downstream manufacturers to replenish stock. Second, the rapid growth in demand for high-performance memory from AI servers has partially offset the softness in consumer electronics demand. Finally, major DRAM manufacturers are controlling capacity expansion, and capital expenditures have declined for two consecutive years, slowing supply growth.
The rise in NAND flash prices is primarily driven by data center and automotive applications. As cloud computing and edge computing develop, the demand for NAND flash in data centers continues to grow, and the trend toward intelligent automotive electronics is also boosting the demand for automotive-grade NAND flash. Furthermore, NAND flash manufacturers are increasing product added value through technological upgrades, and the rising share of high-end enterprise SSDs has also driven the overall price increase.
Semiconductor Supply-Demand Landscape Reshaping, Mature and Advanced Processes Show Increasing Divergence
The chip price trends in September 2026 clearly reflect the structural changes occurring in the semiconductor industry. The divergence between mature and advanced processes is intensifying, forming a distinct "dual-track" market structure.
In the advanced process segment, capacity for 3nm and below processes is in high demand, leading to continuous price increases. Leading manufacturers such as TSMC and Samsung maintain advanced process utilization rates above 95%, with lead times reaching 20-26 weeks. This scarcity in advanced processes keeps the prices of high-end products like AI chips and high-performance computing chips high.
In contrast, the mature process market exhibits different characteristics. After a period of oversupply, the supply-demand relationship for mature processes of 28nm and above is gradually improving. Specifically, in mature process products such as power management chips and microcontrollers (MCUs), inventory levels have returned to normal, and prices have begun to stabilize and recover. This divergence trend has significantly changed the profit structure of the semiconductor industry, with advanced process manufacturers continuously increasing their profit margins, while mature process manufacturers face greater competitive pressure.
Implications for SGX Technology Sector and Investment Strategies
The divergent chip price trends have had a profound impact on the technology sector of the Singapore Exchange (SGX). In terms of market performance, the stock prices of AI chip design companies, wafer fabrication enterprises, and automotive semiconductor suppliers were strong in the third quarter of 2026, while memory chip manufacturers' stock prices were relatively weak.
From an investment perspective, the structural changes in the semiconductor industry offer new opportunities for investors. On one hand, leading enterprises in the AI chip and automotive semiconductor fields are expected to continue achieving above-average profit margins due to their technological and capacity advantages. On the other hand, although the memory chip industry faces challenges in the short term, investment opportunities may also emerge with the improvement in the supply-demand relationship and the approach of new technology cycles. For investment strategies in the SGX technology sector, investors are advised to focus on the following areas: First, pay attention to wafer fabrication companies with advantages in advanced process technology, such as SMIC and Hua Hong Semiconductor; second, position leading enterprises in the AI chip and automotive semiconductor fields, such as ASMI and UMC; finally, monitor high-quality companies in the semiconductor equipment and materials sectors, as these companies will benefit from the industry's upgrading process.
Conclusion and Outlook
The chip price trend in September 2026 clearly reflects the structural changes in the semiconductor industry. The sustained leadership of AI chips and automotive chips demonstrates a profound shift in downstream application demand, while the turning point in memory chip prices signals a cyclical transition for the industry. This divergence trend is expected to continue over the next 12 to 18 months, further reshaping the competitive landscape of the semiconductor industry.
For industry participants, the key to responding to this change lies in accurately grasping the demand characteristics of different segments, optimizing product structures, and strengthening supply chain management.
