Overview

• Shares fell as much as about 9% on Tuesday, marking a fifth straight decline and leaving the stock down roughly 15% since August 13.
• The slide tracked weakness in other AI-linked names, with NVIDIA down up to 3%, Meta off nearly 2%, and the Nasdaq lower by about 1.4%.
• Citron Research targeted the stock with a short report arguing severe overvaluation and suggesting a $40 share price if OpenAI’s price-to-sales were applied.
• Despite the pullback, Palantir recently posted its first $1 billion quarter and lifted full‑year revenue guidance to about $4.14 to $4.15 billion.
• Valuation remains stretched at roughly 253 times expected earnings and about 90 times expected sales, while profit-taking and geopolitical signals were cited as additional pressures.
