Palantir Slides by Most in a Year as Sales Forecast Falls Short

Palantir Technologies Inc. shares slid by the most in nearly a year after its financial results and projections failed to live up to investors’ lofty expectations.

The company described rising demand for artificial intelligence software as a “ravenous whirlwind” and bumped its 2025 revenue forecast on Monday to about $3.9 billion from about $3.75 billion. But even a solid earnings results beat and the raised outlook wasn’t enough to justify the stock’s high valuation and extend its massive year-to-date gain.
