Palantir Technologies (PLTR) shares closed at $189.67 on September 25, 2026, after trading as high as $194.68 earlier in the week amid continued momentum from the company’s Q2 2026 results. Revenue surged 93% year-over-year to $1.935 billion, with U.S. commercial revenue jumping 149% to $764 million and overall U.S. revenue rising 115%. Adjusted operating margins reached 62%, and management raised full-year 2026 revenue guidance to $8.15–8.158 billion (82% growth) plus elevated adjusted free cash flow targets. These results underscore accelerating AI platform adoption and large contract wins, supporting elevated valuation multiples near recent highs. With no major earnings or regulatory catalysts immediate in the final days of September, short-term price action will likely hinge on broader tech sector sentiment, Treasury yields, and any incremental commercial deal flow that could influence the week’s closing level.
