Palantir (PLTR) shares, recently trading near $190 after closing at $189.67 on September 25, have rallied sharply on exceptional Q2 2026 results that featured 93% year-over-year revenue growth to $1.94 billion, 149% U.S. commercial expansion, and a substantial full-year revenue guidance raise to roughly 82% growth. This momentum, fueled by accelerating AI platform adoption and major government and enterprise wins, has lifted the stock nearly 80% from June lows amid elevated multiples exceeding 160 times trailing earnings. Trader sentiment for an end-of-October close hinges on sustained AI demand and risk appetite in tech equities versus potential profit-taking or broader market volatility ahead of the November 2 earnings release. Options pricing reflects notable expected moves through late October, underscoring the sensitivity to near-term catalysts.
