Traditional enterprises achieve digital transformation through AI technology, not only reducing operational costs but also creating new revenue sources and growth points. This shift makes AI investment no longer just a technology investment but an investment in the entire business ecosystem.

3. Driving Force for Innovation

AI technology is becoming a core force driving innovation. According to patent data from the first half of 2026, global AI-related patent applications increased by 45% year-on-year, with Chinese enterprises accounting for over 35% of applications, ranking first globally. This innovation vitality is reflected not only at the technical level but also at the application level.

Breakthroughs in AI technology are spawning entirely new product and service forms. For example, multimodal large models can process text, images, audio and other data types simultaneously, bringing richer interactive experiences to users; AI-driven automated content creation tools are changing the production methods of media and entertainment industries; AI-assisted drug development platforms have shortened the new drug development cycle by 40%, significantly reducing R&D costs.

III. Core Track Positioning for AI Investment

1. Computing Infrastructure

Computing power is the cornerstone of AI development and one of the highest value segments in the AI industry chain. In 2026, global AI computing demand increased by 65% year-on-year, while supply growth was only 40%, with the supply-demand gap continuing to widen. This trend makes computing infrastructure providers the preferred targets for AI investment.

In the computing power sector, focus on three types of enterprises: chip manufacturers such as NVIDIA and AMD specializing in AI acceleration chips and domestic chip companies; cloud service providers such as Amazon AWS, Microsoft Azure, and domestic Alibaba Cloud, Tencent Cloud; and data center operators that build and operate high-efficiency data centers to provide physical support for AI computing power.

2. Large Models and Algorithms

Large models are the current core direction of AI technology development and one of the most valuable investment areas. In 2026, the global large model market has reached $120 billion, with an annual growth rate exceeding 50%. In this field, focus on enterprises with core technical advantages and abundant data resources.

From an investment perspective, large model enterprises can be divided into three categories: general large model providers such as OpenAI, Google, Anthropic, and domestic Zhipu AI, Baidu Wenxin Yiyi; vertical domain large model developers focusing on specific industries such as finance, healthcare, and law; and large model application service providers that offer industry solutions based on large models.

3. AI Application Scenarios

AI application scenarios are the final destination of AI investment and the key link for value realization. In 2026, AI application scenarios have expanded from early basic applications like image recognition and speech recognition to deep application areas such as smart manufacturing, smart finance, smart healthcare, and smart cities.

In terms of application scenario investment, focus on three types of opportunities: B2B industry applications such as AI quality inspection, AI customer service, and AI risk control, which have clear business value and strong willingness to pay; C2C consumer applications such as AI assistants, AI content creation, and AI education, which have large user bases and strong growth potential; emerging cross-domain applications such as AI + Metaverse, AI + blockchain, and AI + IoT, which are highly innovative and may bring disruptive changes.

IV. Risks and Response Strategies for AI Investment

1. Technology Iteration Risk

AI technology is developing extremely fast, with technology routes and standards not yet fully unified, posing technology iteration risks. For example, the shift from Transformer to MoE (Mixture of Experts) architecture has challenged early enterprises that invested heavily in developing Transformer architecture.
