Palantir shares closed at $189.67 on September 25 after hitting a one-year high near $194 earlier in the week, supported by Q2 2026 results that showed 93% year-over-year revenue growth to $1.94 billion and 149% U.S. commercial expansion. The company raised full-year guidance to roughly $8.15 billion in revenue while securing a new $48.1 million U.S. Army ammunition-management contract and advancing AI platform deployments with partners including Nvidia. Elevated valuation multiples near 163 times trailing earnings and reports of short interest create sensitivity to any growth deceleration or macro risk-off moves. No major catalysts are scheduled for the week of September 28, leaving trader positioning driven by momentum from recent contract momentum and analyst price targets around $195–$225.
