Palantir Technologies (PLTR) shares closed near $188.75 on October 2 amid elevated volatility, supported by accelerating AI-driven demand. The company reported 93% year-over-year revenue growth to $1.94 billion in Q2 2026, with U.S. commercial revenue surging 149%, prompting management to raise full-year guidance to approximately $8.15 billion. Operating margins expanded sharply to 47% GAAP, while customer count exceeded 1,000 and recent partnerships, including with Armada for sovereign AI infrastructure, reinforced backlog visibility. Traders price in sustained momentum from these fundamentals ahead of the November 2 earnings release, though the stock's elevated valuation near 160 times trailing earnings leaves room for swings tied to broader tech sentiment and any shifts in government or enterprise spending.
