Key Moments
Global markets are so reliant on AI that a downturn could wipe out tens of trillions, yet investors are emotionally driven and often buy high, sell low.
Key Insights
Micron and SK Hynix alone accounted for 17% of the global stock market's return in May, highlighting extreme concentration in AI-related stocks.
The wealth generated by AI is not staying with AI workers but is dispersing through the economy, making sectors like luxury goods, real estate, and construction indirectly dependent on the AI trade.
Estimates for wealth wiped out by an AI bubble deflation range from $20 trillion (70% of US GDP) to over $40 trillion, significantly exceeding the $6 trillion loss from the dot-com bubble.
For the first time, stocks, not real estate, are the largest component of American household wealth, meaning a stock market crash would directly impact the median household significantly.
The AI build-out is already growing faster relative to its starting point than historical manias like the British railway mania, electrification boom, and dot-com bubble.
An estimated $3 trillion in AI commitments by big tech companies are not on balance sheets, but tucked away in footnotes, creating an 'AI spending iceberg' with unknown true scale.
The AI bet has consumed the global market
The global stock market's performance is increasingly dominated by a narrow set of AI-related companies. A striking statistic from Acadian Asset Management reveals that in May, just two memory chip companies, Micron and SK Hynix, were responsible for 17% of the entire global stock market's return. These two companies represent only about 1% of the MSCI All Country World Index, illustrating an extreme concentration where a fraction of the market is driving the majority of its gains. This raises serious questions about portfolio vulnerability, as ordinary investors are heavily exposed to this AI-driven momentum. The underlying belief is that AI is a transformative technology poised for enormous growth, justifying the massive capital currently being poured into it. However, the narrative suggests that this enthusiasm is often driven by emotion rather than pure logic, with investors getting caught in the momentum and a perceived 'can't miss' opportunity.
Emotional investing fuels the AI boom
Patrick Boyle argues that while top-tier investors may have rational investment theses, the average investor is driven by emotion, a primal human instinct for decision-making. This emotional pull, combined with the immense capital being funneled into AI, creates a powerful market dynamic. AI acts as a 'hoover' for capital, affecting everything from company profitability and access to funding to overall market attention and excitement. This influx of money can indirectly boost seemingly unrelated sectors, as seen with luxury goods and services catering to those who profit from AI. The narrative surrounding AI fosters an emotional response, leading investors to make decisions based on 'vibes' or a sense of inevitable success, rather than a rigorous, first-principles logical analysis. This emotional undercurrent is a significant concern for Boyle, as it mirrors historical speculative manias that relied on irrational exuberance.
Diversification is no longer a safe haven
Traditionally, diversification has been considered the bedrock of sound investing, a 'free lunch' to mitigate risk. However, the current market landscape suggests this may no longer hold true. The AI trade has permeated nearly every sector, from chip manufacturers and utilities powering data centers to real estate and construction. Even companies not directly involved in AI are seeing their valuations tied to its perceived success. For instance, a utility company in Ohio might be considered an 'AI stock' due to the anticipated demand from data centers. This interconnectedness means that a downturn in AI could have a cascading effect across a much wider range of assets than in previous market cycles. The traditional notion of spreading risk across different sectors is challenged when one overarching theme, AI, has become so deeply embedded in so many areas of the economy.
The scale of potential losses is staggering
If the AI bubble were to deflate, the potential financial fallout is immense. Economists have put forth startling estimates: Dean Baker suggests that if price-to-earnings ratios merely returned to their long-run average, it could erase around $40 trillion from the US stock market. Gita Gopinath of the IMF estimates a dot-com style correction could destroy about $20 trillion in American wealth, plus an additional $15 trillion held by foreigners. Consultants at Oliver Wyman project around $33 trillion wiped out. To put this in perspective, the dot-com bubble burst destroyed about $6 trillion in equity value. These estimates for an AI-driven correction are five to six times larger than that historical benchmark. This isn't just theoretical 'paper wealth'; as of this year, stocks have overtaken real estate as the primary component of American household wealth, making a stock market crash a direct concern for the median household, not just the wealthy.
The wealth effect amplifies both booms and busts
The intertwining of stock market wealth with household finances creates a powerful 'wealth effect.' When stock portfolios grow, people feel richer and tend to spend more on discretionary items like cars, vacations, and home improvements. Research suggests that for every $100 in stock wealth, people spend about $3. Conversely, if tens of trillions in household wealth evaporate, consumer spending would drastically decrease. This pullback would have ripple effects through the real economy: canceled renovations mean fewer jobs for contractors, reduced car sales impact dealerships, and a general decrease in spending leads to layoffs. This effect is amplified because, unlike in previous eras where housing was the primary store of wealth, stocks now represent the median household's wealth. This means a stock market downturn directly impacts the spending power of a much broader segment of the population, potentially triggering a significant economic slowdown even without a banking crisis.
Historical manias offer a cautionary tale
The current AI build-out is being compared to historical speculative manias, with concerning parallels. The Bank for International Settlements (BIS) notes that the AI expansion has already grown faster than the British railway mania of the 1840s, the electrification boom of the 1920s, and the dot-com bubble, relative to their starting points. During the railway mania, investors poured vast sums into new lines, with cumulative investment reaching nearly half of Britain's GDP by 1850. Despite the transformative nature of trains, by 1850, railway shares had lost about two-thirds of their value due to over-investment in unprofitable routes. Similarly, the dot-com bubble saw companies overbuild infrastructure like fiber optic cable ('dark fiber') far beyond immediate demand. These historical examples show that even when a technology is real and world-changing, investors who overpay for it during the speculative frenzy can be wiped out, even if the underlying technology eventually succeeds. The AI build-out is currently in its third year, with earlier manias typically breaking around year five.
The opaque world of private credit adds new risks
The financial system's increased safety in traditional banking has pushed risk into less regulated areas, such as private credit. This market, now valued at $2-3 trillion, lends directly to companies outside the traditional banking system. Recent reports indicate a rise in troubled loans within large private credit funds, with some experiencing record default rates. This sector is deliberately opaque, making it difficult to assess the true extent of the risk. The fear is that this mirrors the conditions before the 2008 crisis, where risky lending moved from banks to shadow entities. While current default rates may be low in absolute terms, the rapidly increasing rate of growth in troubled loans is a significant concern, indicating a 'direction of travel' toward greater instability. The inability of some private credit funds to return capital to investors signals potential liquidity issues and a search for increasingly risky debt, a worrying sign for overall financial stability.
Even picking winners can lead to long-term losses
Even for investors who believe in AI and try to pick the winning companies, the timing of entry can be devastating. During the dot-com bubble, Amazon, a clear long-term winner, saw its stock price fall by approximately 90% after peaking in 1999. An investor who bought at the peak would have had to wait until 2009 to break even. Furthermore, most investors during that era did not buy just one stock; their portfolios were diluted by many other companies that went bankrupt, significantly impacting overall returns. The challenge lies in the fact that the companies that eventually become dominant winners often barely existed or were not prominent during the speculative bubble. History shows that being first with a transformative technology often means being an expensive 'rough draft' for later, more successful companies. Therefore, even identifying the 'right' technology does not guarantee investment success if the timing of entry is at the peak of speculative fervor.
