# Palantir stock slides despite record-breaking revenue growth

Record quarter reported: Palantir's Q1 revenue soared 85% year-over-year to $1.63 billion, with U.S. commercial sales up 133% and operating margins reaching 60%. Stock still sliding: Shares are down over 23% in 2026, underperforming the S&P 500 despite record results and raised guidance. Valuation fears linger: High P/E multiples, slowing international growth, and AI competition from Anthropic and OpenAI keep investors cautious.
