Palantir (PLTR) shares closed at $190.04 on October 1, 2026, amid sustained AI-driven demand for its ontology-based analytics platform. Revenue grew over 78% year-over-year in recent quarters, with U.S. commercial bookings accelerating sharply and government contracts providing stable scale. A new partnership with Armada for sovereign AI infrastructure highlights expanding enterprise and allied-nation opportunities. The stock trades at a forward P/E near 99 with a market cap exceeding $450 billion, reflecting high expectations priced into near-term levels. Q3 earnings, due November 2 after the October close, represent the next major catalyst, while broader tech sentiment and any shifts in Fed policy expectations could influence volatility through month-end.
