Palantir shares traded in a volatile range near $187–$193 during the final week of September 2026, closing at $187.48 on September 28 after earlier sessions near $192–$194. Strong Q2 results released in early August—U.S. commercial revenue up 149% year-over-year and full-year guidance raised to 82% revenue growth—continue to underpin bullish sentiment, reinforced by AI Platform adoption and a sovereign-AI collaboration with NVIDIA. Offsetting factors include elevated valuation multiples above 150 times earnings, recent profit-taking from the $207 high, and scattered ETF flows, leaving the week’s closing bin contested among the $184–$192 ranges while the sub-$180 and above-$198 tails reflect uncertainty ahead of the November 2 earnings release.
