May’s job report stunned Wall Street. The Labor Department added 172,000 positions, more than double analysts’ forecast, and halted hopes for a Fed rate cut. Investors dumped shares, driving the Dow down 700 points and the S&P 500 lower 2.7%. This slide hit tech giants hard, with the sector’s nine trillion‑dollar names losing 5.3% on the day and investors retreated.

AI chip leaders bore the brunt: Nvidia fell 6%, Broadcom slid nearly 8%, and Micron dropped 13%, wiping out about $1.1 trillion in market value. Analysts warned that SpaceX’s looming IPO could trigger a rotation away from established megacaps, as portfolio managers seek new liquidity in a potentially high‑growth listing ahead of a potential valuation spike and a market shift.

Weekly totals reflected the worst S&P decline since May 2023, while the Nasdaq slipped 4.7%, its steepest drop since early 2024 tariffs. Smaller firms, however, gained ground, suggesting a shift in investor appetite. The episode underscores how macro surprises and IPO speculation can realign market weight, forcing tech leaders to defend their valuations amid rising rate uncertainty and investor pressure.
