Wall Street is having an argument it has had before — just with different technology at the center. Strategists are openly debating whether the AI-driven stock rally resembles 1997, the early and sustainable phase of the dot-com boom, or 1999, the frothy, crash-preceding peak.
A Bank of America fund manager survey, reported by Bloomberg, landed on the more optimistic side: the AI stock rally is currently in a "boom phase," not "euphoria." That framing suggests, in BofA's read, that the market has not yet tipped into the kind of irrational exuberance that precedes a collapse.
But not everyone is so sanguine. According to a piece in The Hill, some analysts are warning the AI bubble could turn out to be worse than the dot-com bust. The argument: speculative excess is building alongside heightened enthusiasm, and current market valuations may not be sustainable. Yahoo Finance's coverage of the same opinion piece notes that concerns about "potential risks surrounding the AI-driven stock" environment have grown louder.
Fortune frames the standoff bluntly, describing strategists as having "bubble brain" — so fixated on the dot-com parallel that they are essentially arguing over timestamps rather than fundamentals.
The 1997-versus-1999 shorthand matters because the difference is enormous in practical terms: investors who got out in 1999 avoided catastrophic losses, while those who stayed through 2000 and 2001 watched trillions in paper wealth evaporate. The fact that serious Wall Street voices are debating which year we are in — rather than whether a bubble exists at all — is itself a signal worth watching.
