AI Profits Spread Beyond Big Tech as Palantir and Caterpillar Surge

Palantir jumped 29.5% on 4 August 2026 after CEO Alex Karp reported 93% revenue growth. Caterpillar rose 5.6% on its first $20bn sales quarter, partly from datacenter turbine orders. Nvidia, Broadcom, and Micron also gained. S&P 500 firms were tracking ~50% EPS growth — the largest since 2021 — as AI-driven earnings spread across software, chips, and industrial equipment.
