On August 6, 2026, the latest data released by the Semiconductor Industry Association (SIA) showed that the global semiconductor market reached a record $1.2 trillion in the second quarter of 2026, up 18.7% year-on-year and 5.3% quarter-on-quarter. This figure not only surpassed the level of the same period in 2025 but also broke the historical peak set in 2022. Driven by the explosive growth in AI computing demand and the accelerating penetration of automotive intelligence, the chip industry is entering a new super cycle. For investors, the answer to why invest in chips is becoming increasingly clear behind this data.
AI Chips: Computing Power Demand Ignites Market Growth
Data shows that in Q2 2026, sales of AI-related chips (including GPUs, AI accelerators, and high-performance computing chips) surged over 45% year-on-year to approximately $320 billion, accounting for 26.7% of the global semiconductor market. This proportion is a significant increase from 21% in the same period of 2025. Shipments of AI chips from leading manufacturers like NVIDIA, AMD, and Intel continued to climb, while TSMC's 3nm capacity utilization rate exceeded 95%, primarily driven by AI chip orders.
"The proliferation of AI is expanding from the cloud to the edge, driving sustained demand for high-performance chips," said Li Ming (pseudonym), a semiconductor industry analyst. "From large model training to inference applications, and then to AI PCs and AI phones, the chip's position as the foundation of computing power is unshakable." This trend directly responds to the core logic of chip investment: in the wave of the AI revolution, chips are the infrastructure of infrastructure.
Automotive Chips: A Dual Engine of Intelligence and Electrification
Besides AI chips, automotive chips were another major highlight in the Q2 market. According to SIA data, automotive semiconductor sales grew 22% year-on-year to approximately $98 billion. Among them, power semiconductors (IGBT, SiC MOSFET) and intelligent driving chips (SoC, MCU) saw the fastest growth. The penetration rate of new energy vehicles continues to rise—global NEV sales exceeded 35% of total vehicle sales in June 2026—and combined with the commercialization of autonomous driving technology, the demand for chips per vehicle is increasing from about $500 to over $1,500.
In Thailand and the Southeast Asian region, the localization of the automotive chip supply chain is accelerating. The latest data from the Thailand Board of Investment (BOI) shows that in the first half of 2026, Thailand's chip industry attracted foreign investment projects totaling over 80 billion baht, with about 60% related to automotive electronics. This provides new growth points for Thailand semiconductor investment.
Memory Chips and Wafer Foundry: Supply-Demand Dynamics Continue to Improve
The memory chip market also saw a significant recovery in Q2. Sales of DRAM and NAND Flash increased by 8% and 12% quarter-on-quarter respectively, with a clear trend of prices bottoming out and rebounding. Demand for High Bandwidth Memory (HBM) from AI data centers was the biggest driver, with Samsung, SK Hynix, and Micron all running their HBM production lines at full capacity. This confirms the recovery logic of the memory chip market: AI-driven memory demand has long-term sustainability.
In the wafer foundry sector, TSMC's July 2026 revenue grew 33.4% year-on-year, marking its fifth consecutive month of record highs for the same period. Capacity utilization rates at manufacturers like UMC and SMIC also generally exceeded 85%. Advanced process nodes (7nm and below) are in short supply, while mature nodes, supported by demand from automotive and industrial chips, are also showing positive momentum. This landscape provides strong support for wafer foundry dynamics and the semiconductor equipment market.
Why Invest in Chips? Three Core Logics Cannot Be Ignored
Based on current market data and industry trends, the answer to why invest in chips can be summarized into the following three core logics:
- Strong certainty of long-term demand growth: Demand for chips from emerging fields such as AI, automotive, IoT, and 5G/6G communications continues to grow. According to Gartner's forecast, the global semiconductor market will exceed $2 trillion by 2030, maintaining a compound annual growth rate of over 8%. As the underlying support for the digital economy and intelligence, the chip's strategic position is irreplaceable.
- Persistent structural gap on the supply side: Advanced process capacity is limited, and mature process capacity is tilting towards automotive and industrial sectors. Moreover, new wafer fabs typically take 3-5 years from planning to mass production. This means the supply-demand imbalance will persist for the next few years, potentially keeping chip prices and manufacturer profitability high.
- Dual drivers of policy and capital: Major global economies have listed the chip industry as a national strategic priority. The first batch of 200 billion yuan from China's Big Fund Phase III has been deployed, the US CHIPS Act continues to allocate funds, and the EU, Japan, South Korea, and Southeast Asian nations have all introduced incentive policies. In Thailand, the BOI's new semiconductor investment plan is attracting the global supply chain to shift to Southeast Asia, creating unique opportunities for regional investors.
Thailand Semiconductor: Capturing the Industry Transfer Dividend
For investors focusing on the Thailand semiconductor market, the current moment is particularly critical. The Thai government has clearly designated the chip industry as a core "future industry," planning to attract 500 billion baht in investment over the next five years to build a Southeast Asian base for semiconductor manufacturing, packaging, and testing. In the first half of 2026, Thailand's EEC special economic zone added three new advanced packaging projects with a total investment exceeding 20 billion baht, expected to create over 5,000 high-tech jobs locally.
Among SET-listed companies, semiconductor-related stocks performed impressively. In Q2 2026, the SET Semiconductor Sector Index rose 12.3%, outperforming the broader market by 8 percentage points. High-dividend semiconductor stocks like Hana Microelectronics and Delta Electronics continued to attract capital. These companies benefit not only from global chip demand growth but also directly from the dividend of supply chains shifting from China to Southeast Asia.
Investment Strategy Suggestions
Based on the current market environment, investors can focus on the following directions:
- AI chip industry chain: Focus on GPU, HBM, advanced packaging, and other segments, especially suppliers deeply tied to leading manufacturers like NVIDIA and AMD.
- Automotive chip sector: Sub-sectors like IGBT, SiC power devices, and automotive-grade MCUs benefit from the long-term trends of new energy vehicles and autonomous driving.
- Southeast Asia semiconductor theme: Semiconductor manufacturing, packaging/testing, and distribution companies in Thailand, Malaysia, and Singapore benefit from supply chain diversification.
- Semiconductor equipment and materials: Equipment leaders like ASML, Applied Materials, and Tokyo Electron, as well as material suppliers for silicon wafers and photoresists, whose performance is highly correlated with global capital expenditure.
Outlook: The Golden Age of Chip Investment Has Just Begun
The Q2 2026 data once again proves that the chip industry outlook remains vast. Although the global economy faces uncertainties like inflation and geopolitics, the long-term value of chips as the core driver of technological innovation is unshakable. For investors, understanding the chip investment logic and seizing structural opportunities will be one of the most important asset allocation directions in the next decade.
As a senior semiconductor fund manager put it: "This is not a short-term cyclical hype, but a long-term transformation driven by a technological revolution. Those investors who truly understand the underlying logic of the chip industry will reap the richest rewards in this transformation." In this era of AI and the Internet of Everything, investing in chips is investing in the future.
