Palantir Technologies, a company that sells data-analysis software to governments and businesses, reported its Q2 2026 results on Monday, August 3, 2026. Total revenue grew 93% compared to the same quarter a year earlier, and revenue from U.S. business customers grew 149% (Palantir IR).

"Year-over-year" (YoY) simply means comparing a period to the same period the year before. It helps you see whether a company is growing, not just whether it had a good few months.

Palantir also raised its forecast — called "guidance" — for how much it expects to grow for the rest of the year. This is the second time this year it has done that. The company now expects full-year revenue to grow 82% and U.S. business revenue to grow 134% (Palantir IR).

Think of guidance like a weather forecast from the company itself. When a company raises its forecast, it's saying demand is coming in stronger than it predicted.

Palantir raised its profit outlook too, expecting roughly $4.9 billion in adjusted operating income for the year. "Adjusted operating income" is a measure of profit that excludes certain non-cash costs, giving a cleaner view of how the core business is performing (Palantir IR). The stock rose 29.5% on Tuesday, August 4, 2026, after the news (CNBC).

The pattern of these forecast changes tells the real story. Back in February, when Palantir reported Q4 2025 results, it initially predicted 61% full-year revenue growth and 115% U.S. business revenue growth (Palantir IR). After Q1, it bumped those to 71% and 120%, backed by 85% total revenue growth and 104% U.S. revenue growth reaching $1.633 billion (Palantir IR). Now the numbers are 82% and 134%.

Each quarter has added about 10 percentage points to the revenue growth forecast and 14–15 to the U.S. business figure.

The growth rate itself has also been speeding up quarter by quarter. Total revenue grew 70% in Q4 2025, then 85% in Q1 2026, then 93% in Q2 2026. U.S. business revenue grew 137% in Q4 2025 and 149% in Q2 2026 — and that second number is on a larger dollar base, which makes percentage growth harder to maintain. Reuters reported the forecast increase was driven by strong demand from both U.S. government and business customers for Palantir's AI-powered software (Reuters). CNBC said the earnings beat was tied to demand for AI, mentioning "sovereign tools" in its coverage (CNBC).

The broader context is that this kind of acceleration is rare for a company of Palantir's size. Most large software companies see their growth rates slow over time, not speed up. The fact that management has raised its full-year forecast by 21 percentage points in two quarters suggests demand is outrunning even the company's own expectations from six months ago. The near-$4.9 billion profit forecast adds another piece: this is not just growth for growth's sake. Management is signaling it expects to make real money, not just chase revenue.

One thing to watch is the gap between U.S. business revenue growth (149%) and overall U.S. revenue growth. In Q1 2026, total U.S. revenue grew 104% to $1.282 billion. Palantir did not break out the full segment detail for Q2 beyond the business line. If business revenue is growing at 149% while total U.S. growth is lower, that means government revenue is still growing but more slowly. That matters because Palantir has historically been built on government contracts.

The 29.5% stock jump in a single day is a signal of its own. The market is not just reacting to one good quarter — it's rethinking what the company is worth going forward. But there's a flip side. When a company raises expectations twice in six months, it sets a very high bar. If growth slows even a little in the coming quarters, the stock could fall hard, even if the company is still growing fast in absolute terms.

Palantir shares its results and financial filings on its investor relations site (Palantir IR), and also publishes shareholder letters, including its Q1 2026 Letter to Shareholders (Palantir). The next major checkpoint will be Q3 2026 results, where the key question is whether the business-side growth keeps accelerating or starts to cool.
