AI Bubble Fears Are Starting to Spill Over

Yet another domino appears to be falling as part of the Ruth Goldberg machine that will eventually pop the AI investment bubble.

Earlier this month, economic forecasters were sounding the alarm that overspending on AI was at a level far more severe than Black Tuesday, the day that jump-started the worst economic catastrophe in the history of the industrial economy. Now, investors seem to be coming to that same conclusion all on their own.

This week, Taiwanese semiconductor giant Taiwan Semiconductor Manufacturing (TSMC) posted its second-quarter earnings results, revealing a staggering revenue of over $40 billion — a record-breaking sum for the company.

While that should come as welcome news to investors, the results had the exact opposite effect, sending shares of TSMC stocks tumbling by four percent. That in turn led the tech-heavy Nasdaq 100 index to fall by 1.4 percent Thursday, compounding losses from Wednesday, Bloomberg reported.

The issue seems to be TSMC’s revision to its capital expenditure. As the key manufacturer for chip design company Nvidia — arguably one of the most pivotal players in the AI boom — TSMC is a major bellwether for investor confidence around the buzzy tech.

The trouble is that, in addition to posting record revenue, the Taiwanese chip firm raised its 2026 spending forecast to a range of $60-64 billion, up from $52-56 billion. That shift will test how much more spending investors are willing to stomach on AI, a technology that has yet to justify the nearly $1.6 trillion spent developing it over the past decade.

Zooming out, the market’s response seems to indicate a few things. For starters, good news is clearly not enough to maintain confidence in the tech industry’s ability to make AI a financial success. It likewise signals that belief in the AI bubble is no longer confined to a few brave contrarians, but is becoming a mainstream narrative, as investors grow wary of an industry which promises the Moon, yet only seems to deliver hot air.
