• Short seller Michael Burry triggered the selloff by suggesting Anthropic’s new Managed Agents product threatens Palantir’s enterprise software market share.
• The market downturn extended to other AI software firms, including Salesforce, ServiceNow, Snowflake, and Cloudflare.
• Despite the price drop, Palantir reported strong Q4 2025 financial results, including 70% year-over-year revenue growth to $1.406 billion.
• Palantir currently trades at a high P/E ratio of approximately 260x, with recent data showing 69 net-negative insider transactions.
