A figure circulating on social media claims that over a trillion yuan has been “wiped out from China’s stock market today.” However, this representation is misleading. The actual situation is even more troubling and unfolded over the course of four months instead of just one afternoon.
China’s STAR50 index, which tracks leading AI and semiconductor companies, has dropped nearly 40% since its peak in July, resulting in an approximate loss of $480 billion in market capitalization. The blue-chip CSI 300 has entered bear territory, declining about 20% from its June high and reaching a 14-month low as tech stocks continued to face downward pressure. This week, Reuters made it clear: the AI bubble in China has burst.
What exactly led to this situation, and why is the cryptocurrency market largely unfazed?
What Triggered the Downfall of AI Stocks in China?
The uncomfortable truth is that no single event can be identified as the cause. There were no fraudulent activities, scandals, or unexpected interest rate increases. Instead, it was a case of excessive funds pursuing inadequate profits.
- Absurdly High Valuations. Despite a 40% decline, the STAR50 still trades at about 100 times its past earnings. In contrast, the Nasdaq 100 trades at around 30 times. This illustrates how far the index had climbed and how much further it might still drop before being considered a bargain.
- Overreliance on AI. Goldman Sachs reports that AI-related stocks constituted 42% of China’s overall market cap and 57% of daily trading volume at their peak. With one sector dominating trading, the market lacked diversification. If AI falters, the entire market suffers.
- Investor Mania Driven by Retail. The A-share market in China is heavily influenced by small individual investors, and much of the rally stemmed from excitement for any stock associated with AI, regardless of its financial health. As one fund manager in Beijing put it, it became a “speculative crazy bull” market until the bubble burst.
- Geopolitical Tensions and Export Restrictions. Anxiety surrounding potential bans on Chinese tech in data centers by the U.S. and allied nations, along with increasing restrictions on tech investments, diminished one of the sector’s biggest growth narratives.
- Regulatory Intervention from Beijing. On October 9, Chinese authorities issued measures aimed specifically at curbing investment bubbles in emerging technologies, including AI, effectively signaling to the markets.
- Tax Concerns and Waning Investment. Traders noted factors like tax liabilities at the end of the period and a lack of fresh capital following the summer highs.
The irony is striking. The Chinese government had long encouraged households to invest their savings in the stock market. The outcome was a boom that eventually necessitated a regulatory downshift, resulting in a decline that is now adversely affecting the very retail investors it sought to attract.
Is the AI Bubble in the U.S. Also Deflating?
So far, the answer is no, and this distinction is significant. While Chinese AI stocks were plummeting, the Nasdaq experienced only about a 6% drop from its recent peak.
The variance derives from the nature of the investments. U.S. AI expenditures are largely focused on infrastructure—such as chips, data centers, power contracts, and cloud capabilities. While there can be debates about the returns on these investments, they do come with tangible capital expenditures and actual revenue. A significant portion of the rally in China relied heavily on speculation.
That said, the markets are not entirely isolated. Upcoming earnings reports from Microsoft, Alphabet, and Amazon will be seen as critical indicators of the AI investment landscape. Should these U.S. tech titans indicate any slowdowns in AI spending, the question of “Is America next?” will grow louder.
How Did Bitcoin and Other Cryptos Respond to the Decline in China?
What should particularly concern cryptocurrency investors is that Bitcoin hardly reacted to the market crash.
While the Shanghai index fell 1.3% on Tuesday, Bitcoin remained steady just below $80,000, dipping less than 1% in 24 hours. Ethereum lingered around $2,300, Solana was near $100, and XRP recorded a gain of roughly 2%. Live price updates can be tracked on our crypto prices page.
However, Bitcoin’s lackluster performance in October stems from its own distinct issues:
- The Federal Reserve’s Influence. The market anticipates a 90% chance that the Fed will maintain current interest rates during its October 28 meeting, but the slim chance of an unexpected rate hike— fueled by rising oil prices and persistent inflation— has made traders cautious.
- ETF Withdrawals. In mid-October, U.S. Bitcoin ETFs experienced around $635 million in net withdrawals, leading to institutional selling pressure that limits any potential rally.
- Decline in Treasury Purchases. There has been a pause in strategic buying from Treasury, which eliminated a usual source of demand in the market.
- A Dull October for Bitcoin. Bitcoin is on track to finish October with a decline of over 4% and still sits approximately 37% below its historical high of nearly $126,000.
None of these factors are linked to Chinese semiconductor stocks. In this instance, cryptocurrency is influenced by factors specific to the crypto market and U.S. macroeconomic conditions, rather than being swayed by adverse developments in Asia.
Implications of the China AI Bubble for Cryptocurrency
Three key takeaways:
1. Correlation Doesn’t Equal Consequence. The common belief is that Bitcoin behaves like a leveraged tech stock and declines whenever risk assets falter. This week challenges that notion. Despite a $480 billion drop in one of the world’s largest stock markets, there was negligible impact on the crypto market. Although Bitcoin’s connection to the Nasdaq is tangible, its relationship with Chinese A-shares is minimal, and capital controls restrict the movement of Chinese retail investments between the two.
2. The AI Narrative is a Two-Way Street. For the past 18 months, an “AI boom” has typically benefited all risk assets, including AI-related tokens. However, China recently highlighted the other side of that narrative. If U.S. earnings disappoint this week, the AI crypto tokens—predominantly driven by speculation—could quickly become the first casualties. Stay updated on our charts page for sector trends.
3. Bitcoin’s Position as “Digital Gold” Gains Relevance. The pattern in China is not unfamiliar: a government fosters a market surge only to later intervene with regulations. Bitcoin stands as one of the few assets independent from this cycle. While no drastic price shifts occurred this week, stability has its own significance. In a week where an entire national AI sector shed 20% of its value, Bitcoin’s movement was less than 1%.
Will Bitcoin Maintain the $79,000 Mark This Week?
Currently, Bitcoin must sustain support around $79,000 and aim to reclaim $81,000 to demonstrate any bullish momentum. A decisive dip below $79,000 could usher in a decline to $78,000 and subsequently to $75,000, with the Fed’s decision on Wednesday likely serving as a pivotal moment for price movements.
The decline seen in China serves as a cautionary tale about what can occur when a market becomes overly dependent on a single narrative. Crypto markets have experienced similar situations in the past. The key takeaway from the Shanghai turmoil is not the demise of AI but rather that paying exorbitant prices—like 100 times earnings—for a mere story will eventually lead to disappointment, regardless of the asset class or geographical context.
