S&P 500, NASDAQ Drop as Tech Stocks Face a Steep Sell-off

The stock market ended mixed on Tuesday as investors locked in gains from technology and semiconductor stocks following the previous day’s strong rally.

Oil prices fell sharply by about 5–6%, driven by optimism surrounding a potential U.S.–Iran agreement, which helped ease inflation concerns.

Overall, S&P 500 fell 0.6% to 7,511, while NASDAQ dropped 1.2% to 26,376.

Palantir delivered spectacular results last quarter as US demand for its AI platform keeps accelerating. The company delivered 154% profit growth on 85% revenue growth during the quarter, driven by companies rapidly deploying AI into real-world operations.

US revenue grew 104% year-over-year and now makes up 79% of the company’s total revenue. Note, US revenue growth has accelerated from 68% 4QtrsAgo to 77% 3QtrsAgo, 93% 2QtrsAgo, and 104% last quarter.

Management stated most AI products in the market are still “AI slop”, which means flashy demos that fail in actual enterprise environments, while Palantir Artificial Intelligence Platform (AIP) platform is built to run AI reliably at production scale. The company said customers are now replacing legacy software entirely with AIP, with some clients using it to automate manufacturing, underwriting, logistics, military operations, and even internal CRM systems.
