Big Short's Michael Burry warns AI boom will end badly
Michael Burry, the legendary investor who predicted the 2008 housing crisis and inspired the film "The Big Short," has delivered a stark warning that should make every investor holding technology stocks pause and reconsider their portfolio positions. Through a recent Substack exchange, Burry has sounded the alarm on what he perceives as a dangerous artificial intelligence bubble, specifically targeting market favourites Nvidia and Palantir whilst invoking a Warren Buffett parable to illustrate how excessive spending and irrational exuberance typically end in disappointment for investors. For the millions of Americans whose retirement accounts and brokerage portfolios have become increasingly weighted towards AI-related stocks over the past two years, Burry's latest commentary arrives at a crucial moment when technology shares account for nearly 30 per cent of the S&P 500's total market capitalisation.
The timing of Burry's warning is particularly significant given the extraordinary rally in artificial intelligence stocks since late 2022. NVIDIA, the chipmaker that has become synonymous with AI infrastructure, has seen its share price surge more than 700 per cent over the past two years, transforming it into a three-trillion-dollar company and a core holding in countless investment portfolios. Palantir Technologies, the data analytics firm that Burry specifically criticised, has similarly experienced meteoric gains, with its stock price tripling in 2024 alone as investors bet heavily on the company's AI-powered platforms. These spectacular returns have created a feedback loop in which success begets more investment, drawing comparisons to previous technology bubbles that ended catastrophically for latecomers.
The Warren Buffett Parable and Wasteful Capital Deployment
Central to Burry's argument is an old Warren Buffett story about the difference between productive investment and wasteful capital expenditure. According to Burry's recounting, Buffett once explained how companies often engage in spending sprees during boom times, pouring billions of dollars into projects and infrastructure that ultimately generate minimal returns for shareholders. The Oracle of Omaha's wisdom emphasised that just because everyone else is spending money doesn't mean those expenditures represent sound business decisions or wise capital allocation. In Buffett's framework, truly productive investments enhance competitive advantages and generate sustainable profits, whilst wasteful spending merely follows the herd and destroys shareholder value over time.
Burry applies this framework directly to the current artificial intelligence boom, suggesting that the unprecedented capital expenditure flowing into AI infrastructure mirrors previous episodes of technological exuberance. Major technology companies have announced combined spending plans exceeding 200 billion dollars for AI-related infrastructure over the next year, with Microsoft, Amazon, Google, and Meta leading the charge. Whilst these companies justify such enormous outlays as necessary to maintain competitive positioning in the AI race, Burry questions whether the actual revenue and profit generated by these investments will cover the costs. His scepticism rests on historical precedent—from the railroad bubble of the 1840s to the dot-com crash of 2000—where massive infrastructure spending failed to translate into proportional shareholder returns.
"The spending we're witnessing in artificial intelligence today resembles the fibre-optic cable buildout of the late 1990s," says Thomas Hendricks, Senior Technology Analyst at Clearview Research Partners. "Companies laid enough cable to circle the globe multiple times, yet most of those firms ended in bankruptcy whilst the actual utility of that infrastructure took decades to materialise."
Everyone's wondering if, and when, the AI bubble will pop. Here's what went down 25 years ago...
For individual investors, this perspective carries profound implications. The typical American retirement account has become increasingly concentrated in technology stocks, with many 401(k) plans showing allocations above 40 per cent in the sector. Exchange-traded funds tracking the Nasdaq-100 have attracted record inflows, meaning millions of investors now have substantial exposure to companies like Nvidia, Microsoft, and other AI beneficiaries. If Burry's prediction of a prolonged slump proves accurate, these concentrated positions could experience drawdowns similar to the 78 per cent decline that Nasdaq suffered between 2000 and 2002, devastating retirement savings for investors nearing their golden years.
Market Valuations and the Psychology of Speculation
The valuation metrics supporting current AI stock prices reveal the extent of optimism—or perhaps speculation—embedded in market expectations. NVIDIA currently trades at approximately 50 times forward earnings, a multiple that assumes sustained growth rates far above historical technology-sector averages. Palantir's valuation metrics appear even more stretched, with the company commanding a price-to-sales ratio above 40, implying investors believe revenues will expand dramatically whilst profit margins remain robust. These valuations leave little room for disappointment, a reality that Burry has repeatedly emphasised through his public commentary and investment positioning.
The psychology driving these valuations mirrors patterns observed in previous speculative episodes. Investors extrapolate recent trends indefinitely into the future, assuming that companies benefiting from AI adoption today will maintain their dominance and pricing power indefinitely. This thinking ignores the historical tendency for transformative technologies to create intense competition that erodes profit margins over time. The personal computer revolution enriched early innovators like IBM and Compaq, yet ultimately became a low-margin commodity business. The smartphone boom created enormous wealth for Apple while destroying value for countless competitors. The question facing AI investors is whether current market leaders will prove exceptional or follow the typical pattern of technological disruption.
"Market history shows that revolutions eat their children," notes Patricia Morrison, Chief Investment Officer at Steadfast Capital Management. "The companies that build transformative infrastructure often differ from those that ultimately profit most from its existence. Railroad builders went bankrupt whilst retailers using railroads thrived." Also, here's how the AI Boom Repeats the Mistakes of Abandoned Railroads.
Burry's track record commands attention precisely because he has demonstrated a willingness to stand against consensus when valuations become untethered from fundamentals. His prescient bet against subprime mortgage securities before the 2008 financial crisis generated returns exceeding 700 per cent for his investors, whilst most of Wall Street suffered catastrophic losses. His subsequent warnings about passive investing, cryptocurrency speculation, and pandemic-era market excesses have proved remarkably timely, even when initially dismissed by mainstream analysts. This history suggests that investors should at a minimum consider his current warnings about artificial intelligence as worthy of serious analysis rather than immediate dismissal.
For practical portfolio management, Burry's warning need not prompt wholesale abandonment of technology exposure, but rather careful reconsideration of concentration risks and valuation sensitivity. Investors might examine their actual exposure to AI-related stocks, consider whether current positions reflect conviction or merely momentum-following, and evaluate whether portfolio weightings align with their risk tolerance and time horizons. Those nearing retirement or other primary financial goals might reassess whether current technology allocations represent prudent risk management or dangerous overexposure to a single narrative. The lesson from previous bubbles is not that transformative technologies fail to create value, but rather that early-stage valuations often price in decades of perfect execution, whilst ignoring numerous possible disappointments. As Burry's invocation of Buffett wisdom suggests, distinguishing between productive investment and wasteful capital deployment remains essential for long-term investment success, particularly when market enthusiasm reaches fever pitch, and caution becomes unfashionable.
