U.S. AI Trading Frenzy Collapses as Jobs Data Fuels Fed Hike Fears

The U.S. stock market suffered a dramatic reversal on June 5 as the AI trading boom abruptly cooled. Tech giants, semiconductor leaders, and optical communication firms faced heavy selling, wiping out over USD 1 trillion in market value in a single day. The Philadelphia Semiconductor Index plunged more than 10%, its worst drop since March 2020, while the Nasdaq fell over 1,100 points, down 4.18%.

The catalyst was the stronger‑than‑expected May nonfarm payrolls report, which showed 172,000 new jobs and unemployment steady at 4.3%. The data dashed hopes for Fed rate cuts and revived fears of hikes. Treasury yields surged, the dollar strengthened, and risk assets came under broad pressure. President Trump, speaking aboard Air Force One, said he hoped for lower rates but would leave decisions to Fed Chair Kevin Walsh, insisting the economy was strong.

Major indices tumbled: S&P 500 fell 2.64%, Dow 1.35%. Tech leaders dropped sharply: NVIDIA and Tesla down over 6%, Meta over 5%, Amazon over 3%, Microsoft over 2%, Apple over 1%. Chipmakers bore the brunt: Marvell down 16%, Micron 13%, Arm 12%, Intel and ON Semi 11%, Qualcomm and AMD 10%. Storage and optical communication stocks also plunged, with Western Digital, SanDisk, Applied Optoelectronics, Corning, and Coherent among the hardest hit.

Analysts said crowded positioning and high valuations in AI and tech magnified the sell‑off. CME FedWatch now shows markets betting on a December hike. Morgan Stanley’s Ellen Zentner noted the jobs data underscored resilience but kept focus on inflation. Carson Group’s Ryan Detrick said the rally’s dam “finally broke,” while Principal’s Seema Shah warned hikes could enter the agenda if jobs stay strong.

The sell‑off sparked debate over whether the tech bull market is ending. Nationwide’s Mark Hackett said investors are questioning peak growth after strong AI earnings. Yet Wells Fargo’s Ohsung Kwon argued the pullback was positioning‑driven, not fundamental, and semis remain in a bull market. Bloomberg’s Michael Ball saw repricing of crowded AI capex themes, not collapse. Louis Navellier cited profit‑taking and rate pressure, while Renaissance’s Neil Dutta said hikes tied to job growth are not necessarily bearish.

Geopolitical risks add pressure. Middle East tensions and uncertainty over the Strait of Hormuz raise fears of energy‑driven inflation. With giants like SpaceX preparing to list, Wall Street is unlikely to burst the AI bubble outright, but volatility is set to remain high.
