Palantir (PLTR) shares closed September 30, 2026, near $187 amid elevated valuation multiples around 150 times trailing earnings, reflecting strong trader focus on its accelerating AI monetization. Q2 results showed 93% year-over-year revenue growth to $1.94 billion, with U.S. commercial revenue surging 149% and operating margins expanding sharply to 47%, prompting management to raise full-year 2026 revenue guidance to $8.15–8.158 billion. High remaining deal value and expanding AIP deployments in enterprise and sovereign AI settings underpin momentum, though the stock has traded in a wide $106–$207 range over the past year. The next earnings release on November 2 falls after month-end, leaving October price action driven by broader tech sentiment, Treasury yields, and any shifts in growth expectations ahead of that report.
