Palantir Technologies reported Q2 2026 results on Monday, August 3, 2026, with total revenue growing 93% year-over-year and U.S. commercial revenue surging 149% year-over-year. The company raised its FY2026 revenue guidance to 82% YoY growth and its U.S. commercial revenue guidance to 134% YoY growth, marking its second guidance increase of the fiscal year (Palantir IR).

Palantir also raised its FY2026 adjusted income from operations guidance to a range of $4.889 billion to $4.897 billion in the Q2 results (Palantir IR). The stock rose 29.5% on Tuesday, August 4, 2026, following the release (CNBC).

The trajectory of Palantir's guidance revisions across fiscal 2026 is itself the story. In Q4 2025 results (reported February 2, 2026), the company issued initial FY2026 revenue guidance of 61% YoY growth and U.S. commercial revenue guidance of 115% YoY growth (Palantir IR). After Q1 2026, those numbers moved to 71% and 120%, respectively, on the back of 85% YoY total revenue growth and 104% YoY U.S. revenue growth reaching $1.633 billion (Palantir IR). Now, post-Q2, the full-year top-line growth guidance sits at 82% and U.S. commercial at 134%. Each successive quarter has added roughly 10 percentage points to the consolidated revenue growth guide and 14–15 to the U.S. commercial figure.

The quarterly sequential acceleration is equally notable. Q4 2025 total revenue grew 70% YoY; Q1 2026 came in at 85%; Q2 2026 hit 93%. U.S. commercial growth specifically has gone from 137% in Q4 2025 to 149% in Q2 2026, a segment already growing off a larger base. Reuters reported the guidance raise as driven by strong demand from both U.S. government and commercial customers for Palantir's AI-powered data software (Reuters). CNBC attributed the earnings beat to customer demand for AI, including references to "sovereign tools" in its coverage (CNBC).

The broader context here is one of compounding acceleration at a scale that most enterprise software companies do not sustain. Quarterly revenue growth rates that move from 70% to 85% to 93% over three consecutive quarters, each on a sequentially larger revenue base, are unusual in large-cap software. The fact that management has raised full-year guidance by a cumulative 21 percentage points (61% to 82%) across two quarters signals that the demand environment is outrunning even Palantir's own internal models from just six months ago. The adjusted operating income guidance of nearly $4.9 billion adds a profitability dimension to the narrative: this is not growth at any cost, or at least management is signaling it does not expect it to be.

One area worth watching is the gap between U.S. commercial growth (149% YoY) and overall U.S. revenue growth. In Q1 2026, total U.S. revenue grew 104% YoY to $1.282 billion, and the segment breakdown was not explicitly provided in Q2 figures beyond the commercial line. If commercial is growing at 149% while total U.S. growth is materially lower, that implies U.S. government revenue, while still expanding, is growing at a slower clip than the commercial side. That would be a meaningful shift for a company historically anchored by its government contracts.

The 29.5% single-session stock move is a separate signal. At that magnitude, the market is repricing not just the quarter but the forward trajectory implied by the raised guide. The risk for holders is straightforward: guidance that has been raised twice in six months sets a high bar for the back half of the year, and any deceleration in sequential growth, even if absolute growth remains high, could produce an asymmetric reaction in the other direction.

Palantir publishes its quarterly results and SEC filings on its investor relations site (Palantir IR), and supplements earnings with shareholder letters, including its Q1 2026 Letter to Shareholders (Palantir). The next data point for investors will be Q3 2026 results, where the key question is whether the commercial acceleration holds or begins to moderate off an increasingly demanding base.
