As of this writing, Zhipu's stock price has hit a new all-time high of HK$2,514, a 20% surge in a single day, bringing its total market capitalization to HK$1.12 trillion.
Even more impressive is that in less than six months since its listing in January this year, Zhipu's stock price has increased by over 2,000% from its offering price of HK$116.1.

The capital market is frantically chasing Zhipu, but while discussions revolve around large models, computing power, agents, and valuations, one detail is increasingly drawing the attention of investors: Zhipu uses the brand domain Z.ai.
Many believe domain names are merely infrastructure left over from the internet era, but in the AI era, domain names are returning to the center of brand competition.
Today, the AI industry is entering a new phase.
As technological capabilities converge and the gap between models narrows, brand becomes a crucial variable determining a company's value. At this juncture, the value of a sufficiently short, internationally-oriented, and scarce domain name is being rediscovered.
Z.ai represents Zhipu.
X.ai represents Elon Musk's AI empire. Today, X is more than just a letter; it's the most recognizable super symbol in Musk's business empire. From X.com to the X platform, and now X.ai, Musk has bet almost his entire future on this letter.
B.ai, on the other hand, has been acquired by Justin Sun, becoming a key brand asset in his AI strategy.

Observing these cases together reveals an interesting phenomenon: the most influential players in the AI industry are unanimously converging on the single-letter ".ai".
The reason is actually not complicated.
Single-letter ".ai" possesses inherent international attributes, unrestricted by language, requiring no translation, and transcending industry boundaries. More importantly, it possesses extreme scarcity.
There are only 26 worldwide, with no new additions and no replication possible. From a brand equity perspective, single-letter “.ai" is practically a“digital landmark" of the AI era; the most scarce resource in the AI era may very well be single-letter ".ai".
The capital market is revaluing AI companies, but the market may not have fully revalued the single-letter ".ai". When Z.ai's market capitalization surpassed one trillion Hong Kong dollars, when X.ai became a crucial entry point into the global AI industry, and when B.ai completed its new round of brand development,
a new trend is becoming increasingly clear: brand competition in the AI era is extending from technological competition to symbolic competition.
Technology determines the lower limit of a product; brand determines the upper limit of a company.
And single-letter ".ai" may well be one of the most imaginative brand assets of the AI era.
DN.com has been deeply involved in the domain name industry for over 20 years and currently possesses a reserve of several rare single-letter .ai domain names, including Y.ai, N.ai, and H.ai. As a rare single-letter .ai asset of the same level, sharing the top-level domain gene with Z.ai and X.ai, its value potential is immeasurable.
Mirendil, an AI company that secured $200 million in seed funding, has already locked in dual-brand domain names.
The trading of domain names with the "high" prefix is heating up again! HighWater.com sold for $200,000, while HighLevel.com leads the pack at over a million dollars.
