Palantir Technologies Inc. ($PLTR) has reached new milestones in 2025, driven by strong momentum in artificial intelligence and defense sectors. The company reported its first-ever quarterly revenue exceeding $1 billion in Q2, marking a 48% increase year-over-year, with earnings per share surpassing expectations. U.S. commercial sales nearly doubled, contributing to eight consecutive quarters of accelerating growth. Palantir's stock price has surged approximately 150% year-to-date and 2,500% since its debut, making it the priciest stock in the S&P 500 at 245 times forward earnings. Despite the rally, some investors express concerns about overvaluation, as the stock trades near all-time highs. Palantir also expanded its multi-year partnership with Japanese insurer SOMPO, where over 8,000 employees use Palantir's Foundry platform daily to enhance senior care, claims processing, and automated underwriting through AI agents. The company has raised its guidance, citing sustained demand for AI solutions.
