U.S. equity indexes ended sharply lower on Wednesday, June 10, 2026, in a broad-based selloff driven by renewed inflation concerns and geopolitical tensions. The S&P 500 closed at 7,266.99, down 119.66 points (-1.62%), while the Nasdaq Composite fell 509.32 points (-1.98%) to 25,169.50, dragged down by a steep decline in technology and semiconductor stocks. The Dow Jones Industrial Average dropped 953.33 points (-1.87%) to 49,918.78, marking its first close below 50,000 in weeks and underscoring the risk-off sentiment that intensified into the close. The coordinated decline across all three major indexes signals a broad retreat in investor risk appetite rather than a sector-specific correction.

The session was shaped by two dominant forces: a hotter-than-expected CPI report showing inflation rising to 4.2% and escalating geopolitical uncertainty following comments from former President Trump indicating Iran would "pay the price," which contributed to a spike in oil prices. Investors reacted to the renewed inflation pressure and potential supply chain disruptions by rotating out of high-growth tech names, with chipmakers like Nvidia, Intel, Micron, and Marvell among the notable underperformers. Fears over the implications for monetary policy, combined with uncertainty around high-profile events such as the anticipated SpaceX IPO and Oracle’s upcoming earnings, further dampened sentiment. Despite some reports noting oil falling below $90 earlier in the day, prices reversed course sharply after the Iran-related comments, reinforcing the day’s risk-averse tone.
