According to Moody’s, artificial intelligence is reshaping businesses while potentially delivering underwhelming returns for investors, sparking concerns that current market valuations mirror historical bubbles like the dot-com era.
Moody’s Baseline AI Scenario Predicts Muted Stock Returns
Financial analysts at Moody’s project that despite significant corporate productivity gains, stock prices may remain flat through the remainder of this year and next. According to Moody’s chief economist Mark Zandi, the internet served as a game-changing technology that ultimately generated substantial profits, yet investors discounted those gains so heavily that stock market valuations surged.
Data shared by Moody’s indicates that average annual returns will slowly dwindle over the coming decade. On a broader scale, the S&P 500 returned 11.7% annually from 2015 to 2025, whereas Moody’s forecasts a 10-year average gain of just 5% from 2025 to 2035.
Did you know? According to Moody’s, AI-linked corporate borrowing has already eclipsed the debt levels recorded during the dot-com boom of the early 2000s.
Parallels to Historical Market Crashes and Bubble Risks
Economists at Moody’s note that stock valuations have only reached current heights during a few historical periods, specifically in the months leading up to the 1929 stock market crash and the dot-com collapse. While today’s AI market has not quite reached the extremes of internet mania, certain metrics indicate the frenzy is more pronounced.
Zandi warned that if the current market trend persists, a stock market bubble is more likely than not. A primary indicator of this phase is when skeptics capitulate after calling out the bubble for so long, causing market caution to disappear. If an AI bubble bursts, consumer spending could plunge due to the wealth effect of high stock prices, potentially triggering a broader economic recession.
Catalysts That Could End the AI Market Boom
Moody’s outlined several potential catalysts capable of bringing an end to the current market rally. Investors might grow impatient and sell their holdings as long-awaited returns from enterprise AI bets face repeated delays.
Despite these market risks, Moody’s acknowledges that history provides room for optimism regarding the broader economy. Comparing AI to previous technological shifts like the personal computer and the internal combustion engine, the firm notes that major disruptions routinely generate substantial income and wealth even while displacing certain jobs.
