Global markets shudder as AI bubble fears collide with robust US jobs

Wall Street suffered its most punishing day in months on Friday, as a wave of selling tore through the technology and semiconductor sectors. The Nasdaq Composite tumbled 4.2 percent, its steepest one-day decline since April 2025, while the S&P 500 shed 2.6 percent in its worst session since October of that year. The Philadelphia Semiconductor Index, a barometer for the chip industry, plunged 10.3 percent—a rout not witnessed since the pandemic turmoil of March 2020. The immediate trigger appeared to be Broadcom’s quarterly earnings, which, though solid, failed to raise forward guidance in a market feverishly priced for exponential AI growth. The semiconductor index alone saw over $1 trillion in market value erased in a single session; Nvidia lost roughly $300 billion, as every component of the index closed in the red.

The sell-off was ignited by an unexpectedly robust US jobs report, which recalibrated investor expectations for monetary policy. The Labor Department announced that employers added 172,000 positions in May, more than double economists’ forecasts of around 85,000, while the unemployment rate held steady at 4.3 percent. This confirmation of a resilient labour market extinguished lingering hopes for near-term Federal Reserve rate cuts. Bond yields surged, making risk assets comparatively less attractive, and the market’s ‘good news is bad news’ dynamic kicked into overdrive. From Stockholm to Sydney, analysts observed that the data shattered a nine-week winning streak for the S&P 500 and raised the likelihood that the Fed’s newly installed chair, Kevin Warsh, might soon steer rates higher.

Ripples spread rapidly across global financial centres. European equity markets opened sharply lower, with Swedish economists warning of heightened vulnerability from continent-wide contagion. In Tel Aviv, traders braced for a knock-on effect on Israel’s technology-heavy exchange, while Russian financial media catalogued the Nasdaq’s largest single-day drop in thirteen months. Middle Eastern outlets reported a parallel crash across asset classes: gold prices slid 3.5 percent, silver plummeted over 8 percent, and bitcoin suffered a steep decline. The combined carnage erased more than $1 trillion from global financial markets in a matter of hours, according to Iranian and Indian press accounts.

The turbulence lands just as three AI-centric firms—SpaceX, Anthropic, and OpenAI—are preparing colossal initial public offerings. French observers questioned whether the rout signals a deflating AI bubble or merely a dip-buying opportunity ahead of these mega-listings. Space Technologies, Elon Musk’s rocket and satellite venture, is reportedly targeting a valuation of $1.75 trillion, while Anthropic recently raised $65 billion in private funding. Indian analyses warned that the ‘mega AI bubble’ may be reaching its limits, as lofty expectations collide with a reality of stubborn inflation and geopolitical headwinds. The sudden repricing of risk has cast doubt on the sustainability of the artificial-intelligence-fueled rally that has propelled US equity indices to record highs.

Looking forward, the Federal Reserve’s upcoming policy meeting under Chair Warsh looms large, with markets now pricing a higher probability of rate increases. The convergence of tightening monetary conditions, stretched technology valuations, and the geopolitical uncertainty surrounding the US-Iran standoff suggests the global tech rout may be more than a fleeting correction. As central banks from London to Beijing monitor the fallout, the episode tests the resilience of a world market still dependent on the AI growth narrative and the easy money that has sustained it.
