Palantir's Rule of 40 Score Hits 155% — But the Stock Still Trades 30% Below Its Peak

Palantir's Q2 2026 results smash estimates with 93% revenue growth, US commercial up 149%, and full-year guidance raised sharply.

The gap between Palantir's operating performance and its share price has rarely been wider. After the data-analytics company posted second-quarter results that blew past Wall Street's expectations, the stock jumped 14.46% in after-hours trading to €125.10. Yet even after that surge, the equity remains roughly 30% below the all-time high it set in November 2025.

For years, skeptics questioned whether Palantir's Artificial Intelligence Platform (AIP) could scale beyond its government and defense roots. The Q2 numbers, covering the period through June 30, 2026, appear to have settled that debate — at least on the fundamentals side.

A Quarter That Rewrote the Playbook

Revenue came in at $1.935 billion, up 93% year over year and comfortably ahead of the consensus estimate of roughly $1.81 billion. The company's "Rule of 40" score — the standard SaaS metric combining growth and profitability — hit 155%, a figure Palantir says even edges out Nvidia's 153%. For context, anything above 40 is generally considered healthy in the industry.

Profitability kept pace with growth rather than being sacrificed to it. GAAP net income reached $1.062 billion, translating to a 55% margin, while adjusted operating income hit $1.194 billion at a 62% margin. Adjusted free cash flow grew 115% to approximately $1.22 billion, a 63% margin. Adjusted earnings per share came in at $0.41, topping the $0.35 analysts had penciled in.

The Commercial Engine Fires Up

The most striking shift is internal. Palantir has long been viewed primarily as a government contractor, but US commercial revenue jumped 149% to $764 million — closing the gap with the US government segment, which grew 90% to $809 million. The two now sit just $45 million apart.

The order book tells an even more aggressive story. US commercial contracts signed during the quarter totaled $2.132 billion, up 153% from a year earlier, while total contract value across all segments reached $3.373 billion. CEO Alex Karp described the surge in his shareholder letter as an "uprising of enterprises" against closed AI models, arguing that customers rejected becoming "vassal states of the language-model labs." Instead, he said, they're choosing Palantir's architecture to retain control over their internal operations and data.

Karp's language was equally colorful in describing demand as "otherworldly" and "beyond all imagination." He also struck a more reflective note, writing that "for the first time, people believe us."

Guidance Goes Up — Sharply

Management responded to the momentum by lifting its full-year 2026 revenue forecast to a range of $8.150 billion to $8.158 billion, up from a prior top estimate of roughly $7.66 billion. The US commercial business is now expected to generate more than $3.424 billion for the year, implying growth of at least 134%.

The balance sheet remains spotless: $9.2 billion in cash and short-term US Treasuries against zero debt. Unrealized gains from Palantir's stake in SpaceX also provided a modest tailwind to GAAP earnings.

The Valuation Conundrum Persists

Here's where the narrative gets complicated. Despite the blowout numbers, the stock has been a difficult hold. Year-to-date, shares are down roughly 30%, and over the past twelve months the decline stands at about 21%. The 52-week high of €179.98, set in November 2025, is now 39.27% away — a gap that suggests the market had priced in even more aggressive expectations, or that the stock's elevated volatility, running at an annualized rate of around 53%, has spooked investors.

The after-hours pop pushed the shares back above their 50-day moving average of €113.48, though the stock still sits below that level on a closing basis. From the June low of €93.30, the shares have already recovered roughly 17%, and chart watchers see signs of a bottoming process.

Analysts remain broadly constructive. The average price target stands at €158.17, implying upside of about 44.7% from current levels. Even as reports surface that authorities in France and the UK are exploring domestic alternatives to Palantir's platforms, military and intelligence officials reportedly acknowledge that no true competitor of comparable scale currently exists.

The central question for the second half of the year is whether the US commercial segment can sustain triple-digit growth. Management's revised guidance is a bet that it can — which makes the third quarter the first genuine test of that wager.
