A wave of selling in technology shares is reviving an uncomfortable question for investors: has the AI-driven stock boom inflated into a bubble?
According to Reuters reporter Saqib Iqbal Ahmed, soaring valuations, dramatic swings in the market value of trillion-dollar companies, and periodic sharp selloffs have fueled growing unease in the U.S. stock market. The concern is not that any single firm is failing, but that prices across the biggest names have run ahead of what their businesses currently earn.
Prominent voices are echoing that caution. Business Insider reports that economist Mohamed El-Erian believes the U.S. stock market is "out of whack," warning of the risk of a near-term "air pocket" for stocks as investors shift their focus toward actually monetizing AI rather than simply betting on its promise.
Increasingly, the debate is about sorting winners from overhyped names. The Motley Fool published a ranking of Wall Street's trillion-dollar stocks — including Nvidia, Apple, Alphabet, Microsoft, Amazon, Taiwan Semiconductor, SpaceX, Broadcom, Tesla, Meta, Micron, Eli Lilly and Berkshire Hathaway — arguing the group holds both bargains and "pretenders." Separately, Trefis weighed competing AI narratives, asking whether BlackBerry's hot AI story is smarter than Microsoft's.
Taken together, the coverage describes a market wrestling with how much of the AI rally is justified by real earnings versus enthusiasm.
Why it matters: Because a handful of giant tech firms now drive much of the market's value, any reckoning over AI valuations would ripple through the retirement accounts and index funds held by ordinary people, not just Wall Street traders.
