Palantir Technologies Inc. ($PLTR) has reached new all-time highs in its stock price, surpassing $140 per share in premarket trading on June 16, 2025, and continuing to climb to around $147 by late June. The company’s shares have shown strong performance year-to-date, rising approximately 87%, with a 92.93% increase since early April, significantly outperforming major indices such as the Nasdaq, S&P 500, and Dow Jones. Palantir's market capitalization has expanded rapidly, placing it among the top 20 largest publicly traded companies globally, surpassing firms like Procter & Gamble, SAP, Home Depot, and ICBC, and approaching the market caps of Johnson & Johnson, Costco, and Netflix. The company reported annual revenues of $3.3 billion, with a fully diluted market capitalization near $400 billion. This valuation implies a price-to-sales ratio of around 120, notably higher than Microsoft’s P/S ratio of 14 at its all-time high. The stock’s momentum has been attributed in part to recent partnerships, including a nuclear sector collaboration, and its sustained growth since April lows. Analysts and market observers have noted Palantir’s rapid ascent and valuation as remarkable and unprecedented within the current market environment.
