Burry Calls Dot-Com ‘Idiots,’ Cuban Responds Amid AI Hype

Michael Burry, the renowned investor, recently ignited debate by criticizing beneficiaries of the dot-com boom, asserting that “Complete idiots made permanent fortunes” during that era. Mark Cuban, a prominent dot-com billionaire, responded playfully to Burry’s strong remarks.

Market Disconnects and Fortunes

Burry, famously depicted in “The Big Short,” specifically targeted the period between the 1998 collapse of Long-Term Capital Management and the dot-com crash in March 2000. He argued that during this span, stock prices became detached from their fundamental values.

Though Burry did not name individuals, his comments implied a critique of figures like Cuban, who sold Broadcast.com to Yahoo for $5.7 billion in 1999. Cuban acknowledged the jab on X, replying with a laughing emoji and the phrase “Complete idiots.”

Cuban further referenced a 2025 post detailing 13 patent applications Broadcast.com’s lawyers had considered before its acquisition. These patents covered innovations such as geographic identification, hybrid networks, reverse auctions, and streaming authentication, underscoring the era’s rapid technological expansion.

AI Hype and Future Valuations

Burry’s latest remarks echo his recent warnings regarding inflated valuations driven by the current artificial intelligence hype, suggesting a potential future market correction. He previously questioned if he was “the last bear” in the market.

Cuban countered Burry’s earlier sentiment with his familiar adage, “Everyone is a genius in a bull market.” Both investors, however, share concerns about the extensive artificial intelligence buildout currently underway.

Burry has cautioned that major tech companies are significantly overspending on microchips and data centers. He warns these investments could rapidly become outdated, posing a risk to their long-term value.

Similarly, Cuban has speculated that efficiency gains within AI could render some infrastructure redundant, humorously suggesting many data centers might eventually be repurposed as pickleball courts. This shared skepticism highlights a cautious outlook from both prominent investors on current market trends.
