The Market Shock: When an Apology Triggers a HK$70 Billion Erosion

In a striking divergence from broader market gains, Hong Kong’s AI large model sector faced a severe downturn, with Zhipu AI (智谱) at the epicenter. During the morning session, while the Hang Seng Tech Index rallied, Zhipu’s shares nosedived 23%, wiping out approximately HK$70 billion in market value—a stark reminder of how sensitive high-flying tech stocks are to operational stumbles. This sell-off was directly precipitated by a public apology letter issued by Zhipu on February 21, addressing fumbles in its GLM-5 model rollout. The Zhipu’s GLM-5 model apology not only exposed internal workflow gaps but also rattled investor confidence in a company that had been a darling of the AI boom, with its stock soaring over 500% since its IPO. The event highlights the precarious balance between innovation speed and execution quality in China’s fiercely competitive AI landscape.

Unpacking the Apology Letter: A Trilogy of Operational Failures

Zhipu’s apology letter, posted on its official channels, candidly admitted to three core failures that fueled user frustration. First, the company acknowledged a lack of transparency in the rules governing its GLM Coding Plan改版, leaving developers in the dark about usage limits and pricing changes. Second, the phased opening or “灰度开放” of the advanced GLM-5 model was criticized as excessively slow, delaying access for eager users and partners. Third, the upgrade mechanism for existing users was deemed粗糙 or粗糙, with confusing pathways and perceived unfairness. In response, Zhipu swiftly rolled out a compensation package: full refunds for affected users, a one-click rollback to previous service tiers, and extensions of service periods. These moves aim to修复用户体验与市场信心, but the immediate market reaction suggests that trust repair will be an uphill battle.

From Market Darling to Volatility Epicenter: Zhipu’s Meteoric Rise and Sudden Fall

Prior to this downturn, Zhipu had been on a tear, buoyed by the launch of its flagship GLM-5 model and a 30% price hike for its coding套餐, which catalyzed a revenue growth narrative. On February 20, the stock closed at HK$725, giving it a market cap of HK$323.2 billion—a staggering ascent from its IPO price. This rally positioned Zhipu as a核心标的 or core holding in the港股 AI大模型板块. However, the Zhipu’s GLM-5 model apology revealed cracks in the facade: overwhelming demand for GLM-5 led to infrastructure bottlenecks, with Pro and Lite versions facing traffic limits during peak times. Coupled with profit-taking from investors who had ridden the steep rally, these issues ignited the sell-off. Data from the Hong Kong Stock Exchange shows trading volume spiked to over 50 million shares on the day of the drop, indicating heavy institutional and retail liquidation.

Institutional Stance: Bullish Analysts Hold Firm Amidst the Turmoil

Despite the precipitous drop, leading financial institutions have not wavered in their positive outlook for Zhipu and the broader AI large model sector. This divergence between market panic and analyst confidence offers a nuanced perspective for sophisticated investors. Institutions like CICC and JPMorgan view the Zhipu’s GLM-5 model apology as an operational hiccup rather than a fundamental flaw, emphasizing the long-term commercial and technological trajectory. Their reports suggest that the core value drivers—proprietary model capabilities and monetization potential—remain intact, providing a buffer against short-term sentiment swings.

CICC and JPMorgan’s Unwavering Targets: A Vote of Confidence in Technology

China International Capital Corporation Limited (中金公司) recently reaffirmed its “跑赢行业” or “outperform” rating on Zhipu, with a target price of HK$688. In a research note, CICC analysts highlighted the technical barriers of GLM-5 and the expansive commercialization space for AI coding tools, projecting a revenue compound annual growth rate (CAGR) exceeding 130% from 2023 to 2027. Similarly, JPMorgan Chase issued its first coverage on February 10, assigning Zhipu an “增持/超配” or “overweight” rating with a HK$400 target and MINIMAX-WP (00100.HK) an “overweight” with a HK$700 target. The bank’s assessment points to the robust model iteration and ecosystem monetization capabilities of leading players. These ratings, accessible via financial data platforms like Bloomberg [link to hypothetical Bloomberg terminal page], underscore a belief that the Zhipu’s GLM-5 model apology is a temporary setback in a larger growth story.

The Mechanics of the Sell-Off: Profit-Taking, Liquidity, and Sentiment Analysis

The sharp decline was not solely due to the apology; it was amplified by market dynamics. With Zhipu’s stock having appreciated over 500% since its debut, many investors were sitting on substantial paper gains, making it ripe for profit-taking at the first sign of trouble. Additionally, the high valuation—trading at a premium to global AI peers—made it vulnerable to corrections. Liquidity data indicates that sell orders clustered around key support levels, triggering algorithmic trading responses. Sentiment analysis from social media and financial forums shows a rapid shift from euphoria to caution, with keywords like “GLM-5 outage” and “refund” trending. This perfect storm of factors turned a single operational misstep into a full-blown market event, erasing HK$70 billion in value within hours.

GLM-5 Under the Microscope: Technical Promise vs. Operational Reality

Zhipu’s GLM-5 model is hailed as a technological marvel, but its rollout has been marred by execution flaws.
