Key Takeaways Michael Burry estimates that major tech firms including Amazon, Meta, Alphabet, Microsoft, and Oracle face approximately $3 trillion in AI infrastructure commitments. The famed
Michael Burry has delivered another stark warning regarding the extraordinary capital deployment by technology giants into artificial intelligence infrastructure. The legendary investor who correctly anticipated the 2008 financial crisis suggests today’s AI spending trajectory mirrors previous market bubbles that culminated in significant losses.
Michael Burry says AI companies are on track to outspend even the dot-com bubble.
He says overspending like this has marked the top of every major bubble over the past 40 years.

Burry outlined his concerns in a detailed Substack analysis released on September 24. His critique centers on five major corporations: Amazon, Meta, Alphabet, Microsoft, and Oracle.
According to Burry’s analysis, these technology powerhouses collectively face approximately $3 trillion in financial obligations connected to AI infrastructure development. This encompasses purchasing agreements, pending lease commitments, financial guarantees, and ongoing construction expenses.
Alphabet emerged as the primary concern in his assessment. Burry calculates that Google’s parent company maintains nearly $900 billion in off-balance-sheet obligations related to its artificial intelligence expansion.
For Meta, Burry identifies approximately $700 billion in pending leases and purchasing commitments. He suggests this figure might climb toward $1 trillion when accounting for the full scope of the company’s obligations.
Drawing historical comparisons, Burry highlighted similarities to the late-1990s technology bubble. He noted that net capital expenditure across S&P 500 constituents has reached its largest proportion of GDP in approximately 40 years.
Burry doesn’t anticipate immediate market disruption. His projection places the emergence of substantial write-offs somewhere around 2028 or 2029.
Beyond spending commitments, Burry has questioned how corporations are depreciating their Nvidia chip purchases. He contends that cloud computing giants are extending the assumed useful lifespan of these processors beyond a reasonable two-to-three-year window.
This accounting approach, according to his calculations, could result in understated depreciation expenses totaling approximately $176 billion across the 2026-2028 period.
Nvidia issued a comprehensive rebuttal to Burry’s assertions. The semiconductor manufacturer distributed a seven-page document to financial analysts defending a four-to-six-year depreciation timeline for its processors.
Nvidia additionally corrected a specific data point from Burry’s analysis, clarifying that it repurchased $91 billion in stock since 2018, not the $112.5 billion figure he referenced.
Micron’s chief business officer provided a contrasting market outlook, informing investors that memory chip demand will exceed the company’s production capacity through 2028. This projection contradicts Burry’s position that current AI demand is artificially inflated.
Burry has backed his thesis with substantial short positions. His bets against the market include Oracle, Nebius, Micron, and Palantir.
He’s also positioned himself against the Philadelphia Semiconductor Index using put options expiring in January 2027. Notably, many of his short targets delivered positive returns through August.
Burry isn’t alone in expressing skepticism. GMO co-founder Jeremy Grantham has characterized current AI market valuations as bubble territory. Jeffrey Gundlach of DoubleLine Capital has predicted that the AI investment wave will produce clear winners and losers.
Despite his bearish AI stance, Burry maintains bullish positions elsewhere. He has initiated full positions across five companies operating outside the artificial intelligence sector.
His selections include roofing materials distributor QXO, natural grocery retailer Sprouts Farmers Market, children’s toy company Build-A-Bear, premium footwear manufacturer Birkenstock, and Latin American e-commerce platform Mercado Libre.
Each of these holdings has experienced double-digit percentage declines year-to-date. Build-A-Bear has suffered the steepest drop, declining as much as 57%.
Micron’s upcoming quarterly earnings announcement carries heightened significance. Analyst consensus projects year-over-year earnings expansion of 940%, per Investor’s Business Daily. This financial report may significantly influence investor sentiment regarding the ongoing AI spending controversy.
