‘Bong bóng’ cổ phiếu chực chờ ngành AI Trung Quốc?

The recent volatility in Chinese artificial intelligence (AI) stocks has sent shockwaves through global financial markets, raising urgent questions about whether the long-anticipated "AI bubble" has finally burst. Over the past four months, the market capitalization of major Chinese technology firms, particularly those integrated into the AI value chain, has plummeted. This sharp contraction has wiped out nearly $480 billion in value, prompting intense debate among analysts, investors, and state-backed media outlets regarding the sustainability of the sector’s growth trajectory.
A Chronology of Market Turbulence
The decline began in earnest around May 2026, marking a turning point for a sector that had previously enjoyed meteoric valuations. For months, investors had poured capital into AI-related infrastructure, ranging from semiconductor manufacturers to software developers, betting on the transformative potential of generative AI.
By late October 2026, the trend had accelerated. Data from the STAR50 index, which tracks the performance of China’s leading high-tech and AI-centric enterprises, revealed a staggering 40% decline in just under four months. The broader market has not been immune to this downturn; major Chinese listed companies across multiple sectors have seen an average value reduction of 20% since the spring. According to financial data provided by Bloomberg, the cumulative loss in market capitalization for the Chinese equity market since May exceeds $2.4 trillion, a figure that highlights the deep-seated instability currently rattling the world’s second-largest economy.
Sector Concentration and Systematic Risk
Goldman Sachs has noted that AI-linked equities currently account for more than 40% of the total market value in both the Chinese mainland and Hong Kong exchanges. This high level of concentration means that the AI sector has become a primary driver of overall market sentiment. When the AI bubble shows signs of distress, the contagion effect is immediate, pulling down traditional sectors and undermining investor confidence across the board.
The situation has been exacerbated by the structural reliance of the Chinese economy on technological advancement as a pillar of future growth. In response to the cooling market, the Chinese government has attempted to stabilize the sector, most notably through the launch of a state-backed AI investment fund worth approximately 60 billion yuan ($9 billion USD) in October. Despite these capital injections, retail investors—who have been historically encouraged to shift savings from traditional bank deposits into stock market investments—have become increasingly cautious, further dampening liquidity.
Official Responses and the Narrative Conflict
On October 27, the Global Times published an editorial titled "The decline of Chinese AI stocks is not a sign of a bubble," attempting to dismiss international media reports that characterized the sell-off as a collapse. The editorial argued that the current downturn is a normal cyclical adjustment rather than a structural failure.
However, many market observers remain skeptical. The Financial Times and Reuters have both pointed to the disconnect between the astronomical valuations of these companies and their actual revenue generation. The concern is that while Chinese firms have heavily invested in hardware and R&D, the consumer demand for AI-driven services has not kept pace with the supply, leading to a "valuation gap" that is becoming increasingly difficult to justify to institutional investors.

Broader Economic Implications and the "Dotcom" Parallel
The current situation bears a striking resemblance to the dotcom bubble of the late 1990s. In both instances, high expectations for a technological revolution fueled speculative investment, often ignoring the fundamental metrics of profitability.
A survey conducted by Deutsche Bank earlier this year, involving 440 investors, economists, and analysts, revealed that 57% of participants identified the potential decline in AI-sector valuations as the primary risk to market stability for the remainder of 2026. Experts argue that the value currently added to the real economy by AI remains far below the levels of capital investment being poured into the sector. This has led to concerns regarding the "return on investment" (ROI), as firms continue to issue massive amounts of corporate debt to fund infrastructure projects that may not yield returns for several years.
The Semiconductor Supply Chain Bottleneck
A critical factor fueling this instability is the global semiconductor supply chain crisis. The boom in AI has driven demand for high-end memory chips and processors to unprecedented levels. Geopolitical restrictions and trade friction between major powers have limited the global supply of these critical components, creating a supply-demand imbalance that has forced prices upward.
As of late October 2026, the cost of standard memory components has surged. For instance, the price of a standard DDR5-6000 RAM module in the U.S. market has climbed to $450—a 12.5% increase since August and a massive jump from the $100–$200 range seen just a year prior.
This scarcity has profound implications for businesses beyond the AI sector. Increased costs for basic computing components are forcing companies to raise product prices, which in turn fuels inflationary pressure and suppresses consumer spending. When businesses must allocate a larger share of their budget to hardware costs, their ability to invest in growth or innovation is severely curtailed.
Future Outlook and Strategic Considerations
The current correction in Chinese AI stocks serves as a cautionary tale for global markets. The fundamental challenge lies in balancing the enthusiasm for technological progress with the harsh realities of capital efficiency and market demand. For China, the stakes are exceptionally high. The government’s attempt to foster a domestic AI ecosystem is not merely a financial strategy but a central component of its national security and industrial policy.
The path forward will likely involve a period of consolidation. Analysts suggest that only companies with strong balance sheets and clear, scalable business models will survive the current period of turbulence. The reliance on cheap credit to fund speculative R&D is likely to decline as interest rates for corporate bonds remain high, reflecting the perceived risk in the technology sector.
In conclusion, while the Global Times maintains an optimistic outlook, the empirical data suggests that the Chinese AI market is undergoing a painful, perhaps necessary, adjustment. The coming quarters will be critical in determining whether this correction leads to a more sustainable, value-driven market or if it signals a deeper, more protracted period of economic stagnation within the tech sector. Investors and policymakers globally will be watching closely, as the performance of the Chinese tech market remains inextricably linked to the health of the broader global financial system.
