Today marks a milestone for the AI sector: Z.ai, a leading domestic large-scale model manufacturer, saw its stock price reach a new all-time high. As of this writing, its total market capitalization has exceeded HK$872.9 billion, officially surpassing Xiaomi Group (currently HK$725.5 billion) and joining the first tier of Hong Kong-listed technology companies.

From a market capitalization of HK$570 billion on May 22nd to exceeding HK$800 billion today, Zhipu achieved a leapfrog growth in just one week, far surpassing traditional internet giants like Baidu, JD.com, and Ctrip. Currently, Zhipu's market capitalization is approximately 2.5 times that of JD.com and 2.4 times that of Baidu. The disruptive effect of AI on the traditional internet has been fully realized in the capital market.
This surge in market capitalization is essentially a handover of power between the old and new tracks in the AI era. Over the past two decades, internet giants built barriers to entry through e-commerce, search, and local services. Premium short domain names like Xiaomi (mi.com) and JD.com (jd.com) were once symbols of their brand strength.

However, with the changing times and AI reshaping industry logic, the value logic of domain names is also being rewritten. If .com is the universal entry point in the internet age, then .ai is becoming a crucial asset for AI companies to establish industry recognition.
Zhipu uses Z.ai as its official global entry point. Z.ai is extremely simple, requires zero memorization, and the initial "Z" precisely echoes "Zhipu," naturally aligning with its AI-related attributes.
The value of Z.ai is a microcosm of the domain name logic in the AI era: the .ai suffix naturally forms a strong association with artificial intelligence, possessing stronger industry recognition and a technological label, accurately reaching a global AI audience without additional explanation.
Industry valuations indicate that rare single-letter .ai domains like Z.ai are worth over seven figures in US dollars, their value no less than that of mi.com and jd.com in their heyday.
Zhipu's market capitalization surpassing Xiaomi's is not only a victory for an AI company, but also a victory for the new value system of the AI era.
Currently, AI upstarts have leveraged their technological and industry advantages to achieve a leapfrog development in the capital market. In the digital asset field, the success story of Z.ai has already proven that:
In the accelerated phase of AI competition, a minimalist, global, and industry-relevant domain name is becoming a crucial component of brand recognition efficiency.
Currently, single-letter .ai domain names like T.ai, Y.ai, and H.ai, similar to Z.ai, are still scarce. They possess three core advantages: perfect quality, extreme brevity, industry relevance, and global usability. They serve as top-tier entry points for AI companies to build benchmark brands and are also high-quality assets in the domain investment field backed by the trillion-dollar AI sector.

From the internet legends of mi.com and jd.com to Z.ai's new chapter in AI, the value evolution of domain names has always closely followed the trends of the times.
The fact that Zhipu's market value has exceeded HK$800 billion proves that in the AI era, choosing the right track and seizing core digital assets are key to capturing the growth dividends of the next decade.
And single-letter .ai domains like T.ai, Y.ai, and H.ai represent a rare opportunity to position oneself in the AI field and replicate the value of Z.ai.
