Dual Drive of AI and Domestic Substitution: In-depth Analysis of 2026 Chip Investment Logic
In 2026, the global semiconductor industry is facing unprecedented development opportunities and challenges. With the rapid development of artificial intelligence technology and the deepening of domestic substitution strategies, chip investment logic is undergoing profound changes. This article will analyze the new logic of current chip investment from multiple dimensions, including the surge in AI chip demand, accelerated domestic substitution, and the rise of Vietnam's semiconductor industry, providing investors with comprehensive decision-making references.
I. AI Chip Investment Logic: Market Demand and Technical Barriers Building Moats
In 2026, AI chips have become the core driving force for the development of the semiconductor industry. According to industry data, the global AI chip market size is expected to exceed $150 billion, with a compound annual growth rate exceeding 35%. This growth is mainly driven by three major demands: large model training, inference, and edge AI applications.
From an investment perspective, the AI chip field shows a clear "the strong get stronger" pattern. International giants such as NVIDIA, AMD, and Intel occupy the dominant position in the high-end AI chip market by virtue of their first-mover advantages and ecosystem construction. However, with the rapid rise of domestic companies such as Huawei Ascend, Cambricon, and Biren Technology, investment opportunities in AI chips are developing in a more diversified direction.
The core logic of AI chip investment lies in the construction of technical barriers and ecosystems. On one hand, advanced process technologies, high-bandwidth memory (HBM), advanced packaging, and other key technologies constitute high entry barriers; on the other hand, the perfection of software ecosystems, developer communities, and industry solutions determines the long-term competitiveness of enterprises. Investors should focus on companies that have both technical strength and ecosystem construction capabilities.
II. Domestic Substitution Investment Logic: Policy Support and Technological Breakthroughs Release Long-term Value
In recent years, domestic substitution has become the core strategy for the development of China's semiconductor industry. In 2026, with changes in the international environment and continuous strengthening of domestic policies, the domestic substitution process is accelerating, bringing new opportunities for chip investment.
From a policy perspective, the establishment of the third National Integrated Circuit Industry Investment Fund (Big Fund III), the continuation of tax preferential policies, and the increased support for the semiconductor industry in the "14th Five-Year Plan" all provide strong policy guarantees for domestic chip companies. Especially in "chokepoint" fields such as equipment, materials, and design tools, there is huge room for domestic substitution.
From a technical perspective, domestic companies have made breakthrough progress in multiple fields. CIMC has reached an internationally advanced level in the field of etching equipment, Siltronic has achieved mass production in the 300mm silicon wafer field, and HiSilicon maintains a leading position in 5G chip design. These technological breakthroughs have not only enhanced the competitiveness of domestic companies but also provided clear investment targets for investors.
The core logic of domestic substitution investment lies in breakthroughs in "chokepoint" fields and the self-controllability of the industrial chain. Investors should focus on companies that achieve breakthroughs in key equipment, core materials, and high-end design tools, as well as "specialized, refined, differential, and innovative" companies that can form competitive advantages in niche markets.
III. Vietnam Semiconductor Industry Investment Logic: Regional Advantages and Development Opportunities
As an emerging semiconductor manufacturing center in Southeast Asia, Vietnam is playing an increasingly important role in the global semiconductor industry landscape. In 2026, with the formal implementation of Vietnam's semiconductor strategy and new breakthroughs in local chip manufacturing, the investment value of Vietnam's semiconductor industry is becoming increasingly prominent.
Vietnam's development of the semiconductor industry has multiple advantages: first, relatively low labor costs with continuously improving skill levels; second, superior geographical location, facilitating connections to global supply chains; third, strong government policy support, with multiple preferential policies introduced to attract foreign investment; finally, Vietnam's adoption rate of the next-generation Internet Protocol IPv6 has risen to 67.68%, ranking second in ASEAN and seventh globally, laying a solid foundation for the development of the digital economy.
In 2026, Vietnam's local chip manufacturing has made significant breakthroughs, with 28nm process technology successfully put into mass production, marking a key step in Vietnam's semiconductor autonomy process. At the same time, the Vietnam Semiconductor Boot Camp has been established in Ho Chi Minh City, focusing on creating a new highland for IC design, packaging, and testing talent to provide talent support for industrial development.
The core logic of Vietnam's semiconductor industry investment lies in industrial chain synergy and regional advantages. Investors can pay attention to semiconductor companies that establish R&D centers or production bases in Vietnam, as well as local companies that provide supporting services for Vietnam's semiconductor industry. Meanwhile, green cooperation and investment cooperation between Vietnam and countries such as Italy and Russia have also brought new opportunities for the semiconductor industry.
IV. Chip Investment Risks and Response Strategies
Although chip investment prospects are broad, investors still need to be vigilant about potential risks. First, the global chip industry shows obvious cyclical fluctuations, with risks of overcapacity and price fluctuations always existing; second, the speed of technological iteration is fast, and investment may face the risk of wrong technology route selection; third, geopolitical factors may lead to supply chain instability; finally, the talent shortage problem is becoming increasingly prominent, which may restrict industrial development.
In response to these risks, investors should adopt the following strategies: first, focus on companies with core technical barriers and long-term competitiveness, avoiding chasing short-term hotspots; second, diversify investments, balancing the investment proportions of different segments and industrial chain links; third, closely track changes in industrial policies and grasp policy guidance; fourth, focus on talent cultivation and technology accumulation, and attach importance to the sustainable development capabilities of enterprises.
V. Conclusion: Long-term Value and Future Outlook of Chip Investment
Looking ahead, chip investment will show three major trends: first, AI chips will continue to lead industrial growth, especially in large model training, inference, and edge computing; second, domestic substitution will expand from "chokepoint" fields to the entire industrial chain, forming a more complete industrial ecosystem; third, emerging markets such as Vietnam will play a more important role in the global semiconductor industry landscape.
For investors, the key to grasping chip investment lies in understanding technological development trends, industrial chain changes, and market demand changes. Under the dual drive of AI and domestic substitution, the chip industry will welcome long-term investment value. Investors should adhere to a long-term perspective, focus on companies with core technological advantages and sustainable development capabilities, and share the dividends of semiconductor industry development under the premise of controllable risks.
Overall, the chip investment logic in 2026 is shifting from short-term speculation to long-term value investment, from single links to the entire industrial chain layout, and from the domestic market to a global perspective. In this context, investors need to continuously improve their professional capabilities and grasp industry trends to obtain long-term and stable investment returns in a complex and changing market environment.
