The global AI investment frenzy has divided economists and industry leaders, with some warning of a looming bubble and others insisting that current spending marks the foundation of a long-term transformation.
According to BofA Global Research, 54% of investors say AI stocks are already in a bubble, though nearly 90% of them remain invested, betting that the market has not yet peaked.
The Bank of England cautioned that a downturn in AI sentiment could trigger a “sharp market correction,” while IMF chief economist Pierre-Olivier Gourinchas said a dot-com-style bust is possible but unlikely to cause systemic damage because AI investments are not debt-financed.
Some industry leaders reject the bubble narrative. ABB CEO Morten Wierod said demand for data centers and AI infrastructure remains strong: “We are talking about trillions in investment, but there aren’t enough people or resources to build all this.”
Amazon’s Jeff Bezos described the boom as part of the innovation cycle — one that funds both breakthroughs and failures: “When the dust settles and you see who the winners are, society benefits.”
By contrast, OpenAI’s Sam Altman warned of investor excess, saying, “Someone is going to lose a phenomenal amount of money.”
Goldman Sachs’ Joseph Briggs maintained that the surge is sustainable, though identifying the long-term winners will be difficult.
Despite mixed views, the consensus is clear: AI investment shows no sign of slowing. With major players from Nvidia to Microsoft pouring in capital, the next few years will test whether the sector’s growth story is solid or speculative.
