Shares surged 6.4% to €158.38 on the Frankfurt exchange as Wall Street doubled down on Palantir's deepening grip on the Pentagon's AI budget. The catalyst: William Blair reiterated an Outperform rating, citing continued expansion of the company's Maven Smart System contract with the Pentagon , with analyst Louie DiPalma saying Maven is on track to hit at least $1 billion in annual recurring revenue — already Palantir's largest contract overall.

  • A Single Contract Is Now Big Enough to Move the Stock. In 2024, the Army signed a five-year deal for Maven worth $480 million. The following year, the ceiling was boosted to $1.3 billion amid surging demand. Now the Pentagon could boost financing by as much as $244 million through March 2027 and is seeking $2.3 billion for Maven and a related targeting network . For a company that reported Q2 2026 revenue of $1.94 billion — about 42%, or $809 million, from U.S. government contracts — Maven alone approaching $1 billion yearly would mean defense AI is becoming the company's center of gravity.

  • "Program of Record" Means the Pentagon Can't Easily Walk Away. A program of record is the point at which a capability stops being an experiment and becomes part of the permanent architecture of the institution: budgeted year on year, written into doctrine, and expected to be there for the next decade and beyond.

The transition locks in multiyear budget streams, solidifying government contracts as a cornerstone of Palantir's business model.

  • Growth Is Scorching, but the Price Tag Is Staggering. U.S. government revenue growth accelerated from 5% in Q4 2023 to 90% in Q2 2026, with overall revenue up 79% year-over-year and gross margins at 84.8%. Yet Palantir's market cap reaches $420.73 billion, and InvestingPro analysis indicates the stock trades above its Fair Value estimate.

The price-to-sales ratio sits above 100 — meaning investors are paying more than $100 for every dollar of annual revenue, a bet that only works if growth stays extraordinary.

  • The Risks Aren't Hypothetical. William Blair flagged competition from cheaper AI tools built on large language models and warned that Maven's momentum could slow after a change in political leadership.

A separate concern: Maven relies on Anthropic's Claude AI, and the Pentagon recently flagged Anthropic as a supply chain risk following a dispute over safety guardrails.

The bottom line: Palantir is building what looks like irreplaceable infrastructure inside the world's largest military. Whether the stock's triple-digit revenue multiple already reflects that — or still has room to grow — is the question every shareholder must answer.
