Palantir Technologies (PLTR) shares closed at $187.48 on September 28, 2026, following a sharp post-earnings rally that lifted the stock more than 50% from levels near $125 in early August. Second-quarter results showed revenue of $1.94 billion, up 93% year-over-year, with U.S. commercial revenue surging 149% and total contract value reaching record levels, prompting the company to raise full-year 2026 guidance to at least $8.15 billion in revenue and 82% growth. Strong adoption of its Artificial Intelligence Platform, expanding government contracts, and partnerships such as with NVIDIA have supported momentum, though the stock trades at a premium valuation with a trailing P/E near 160 and remains sensitive to broader tech sentiment and any shortfall in commercial pipeline execution. Next quarterly results are scheduled for November 2.
