Why Palantir Stock's Massive Breakout Was Old News

Palantir Technologies' stock gained 34% during the three months ending in late August, versus 2.1% for the S&P 500. The August 3 second-quarter report received the credit. Yet almost everything it verified had already been signed, filed, or stated publicly by early May. The advance was visible beforehand.

Stellantis, The USDA And Cleveland-Cliffs Signed First In late March, the company extended and expanded its Stellantis partnership for another five years, widening Stellantis’s use of Palantir Foundry and incorporating Palantir’s AI platform. In April, the USDA granted a contract worth up to $300 million to protect farmland and update services for farmers, while Cleveland-Cliffs entered into a three-year agreement placing Palantir’s AI at the core of its operations and commercial processes. Trailing-twelve-month revenue as of fiscal Q1 2026 stood at $5.22 billion, meaning none of these developments alone was transformative; what mattered was that all three had been agreed upon before the price moved.

The Expansion Rate Rose Through Three Quarters Contracts are uneven. The clearer signal was net dollar retention, which measures what current customers spend versus a year earlier, excluding customers acquired during the previous twelve months. Retention was 134% in fiscal Q3 2025 and 139% in fiscal Q4 2025, before rising 1,100 basis points to 150% in fiscal Q1 2026, the biggest increase in that stretch and already on record by early May. That rise is not an AI forecast; it reflects existing customers are paying more. The growth was profitable as well: trailing operating margin as of fiscal Q1 2026 was 38.1%, compared with a three-year average of 14.2%.

AI Sovereignty Was A Fresh Name For Existing Momentum The thesis also came before August. In early May, the company’s revenue chief described the opportunity as enterprises recognizing the danger of relying solely on models. On August 3, it received a name and a number: U.S. commercial revenue increased 149% year over year to $764 million in fiscal Q2 2026, and full-year 2026 revenue guidance was raised to a midpoint of $8.154 billion , representing 82% growth year over year and an 11-point increase over the prior guide’s growth rate. Management describes this demand as AI sovereignty, referring to customers seeking to keep their data, logic, and security under their own control rather than an outside lab’s. Demand continued to come in after f...
