Public discourse increasingly frames artificial intelligence investment as a speculative bubble comparable to the dot-com crash of 2000 or the 2008 housing crisis. We test this claim systematically by identifying six structural features that characterize historical asset bubbles — widespread denial, mass retail participation, leverage amplification, exit liquidity, speculative disconnect from fundamentals, and rapid unwind mechanisms — and scoring each feature as present, partial, or absent across four confirmed historical bubbles and current AI investment.
