Shares of artificial intelligence (AI) data and analytics platform specialist Palantir Technologies (NASDAQ: PLTR) experienced a nearly 7% slide on Tuesday following its latest earnings release. This recent pullback contributes to a challenging year for shareholders, with the stock now down more than 20% in 2026 and trading roughly a third below its November all-time high. Despite a headline-grabbing revenue acceleration, a deeper dive into the company’s forward-looking metrics reveals a more nuanced picture that continues to fuel skepticism regarding its lofty valuation.
Palantir’s Revenue Soars, But Shares Slide
On the surface, Palantir’s first-quarter performance was robust. The company reported revenue of $1.63 billion, marking an impressive 85% year-over-year increase. This figure represents Palantir’s highest top-line growth rate since becoming a public entity and extends its streak of accelerating revenue growth to 11 consecutive quarters. To put this trend into perspective, year-over-year growth rates over the past five quarters have progressed from 39%, to 48%, 63%, 70%, and now 85%.
The company’s U.S. business, which now accounts for 79% of total revenue, was a significant driver, growing 104% year over year in Q1 and crossing the triple-digit threshold for the first time. Management also demonstrated confidence by raising its full-year 2026 revenue guidance to a midpoint of $7.66 billion. This revised outlook implies a 71% growth rate for the year, representing a 10-point boost from the prior guidance. Furthermore, Palantir’s non-GAAP (adjusted) operating margin came in at an impressive 60%.
Given these strong top-line figures, the stock’s decline might seem counterintuitive. However, the market’s reaction suggests investors are looking beyond the immediate revenue growth to underlying trends in future business generation.
Decelerating Bookings Cloud the Outlook
The more measured story emerges when examining Palantir’s forward-looking metrics, particularly its contract bookings. Closed total contract value (TCV), defined by Palantir as ‘the total potential lifetime value of contracts entered into with, or awarded by, our customers at the time of contract execution,’ reached $2.41 billion in Q1, representing a 61% year-over-year increase. While substantial, this marks a sharp deceleration from the $4.26 billion in TCV closed during the fourth quarter, which saw a 138% growth rate.
The U.S. commercial segment of TCV also showed signs of cooling, growing 45% year over year compared to 67% in Q4. Chief Financial Officer David Glazer offered a more favorable interpretation on the earnings call, noting that ‘on a dollar-weighted duration basis, TCV bookings grew 135% year-over-year.’ This suggests that a portion of the reported TCV deceleration could be attributed to shorter contract durations rather than a complete slowdown in new business acquisition.
However, the unadjusted figures directly impact the company’s reported backlog. U.S. commercial remaining deal value (RDV), which represents the remaining value of contracts at the end of the reporting period, grew 112% year over year and 12% sequentially to $4.92 billion. While positive in isolation, the trend in year-over-year growth for U.S. commercial RDV has visibly compressed over the past three quarters, moving from 199% to 145% to 112%. Similarly, sequential growth rates for this metric have tightened from 30% to 21% to 12% over the same period. Total companywide RDV grew a more modest 6% sequentially.
CEO Alex Karp did not directly address this softening in bookings and backlog metrics. Instead, he informed analysts that the company’s ‘biggest problem currently in the U.S. […] is that we just cannot meet demand.’ While this may be true in the present, the decelerating trends in TCV and RDV suggest that the current gap between contract momentum and revenue acceleration may not be sustainable indefinitely.
Valuation Remains a Sticking Point
Even after the more than 20% pullback in its share price this year, Palantir’s stock continues to trade at an extraordinarily high valuation. As of the time of the report, the company commanded a market capitalization of approximately $325 billion against trailing-12-month revenue of about $5.2 billion. This translates to a price-to-sales (P/S) ratio in the low 60s, a multiple that prices in many years of the exceptional performance Palantir has recently delivered. Even when considering management’s full-year 2026 revenue outlook, the forward P/S ratio still hovers in the low 40s. Furthermore, the stock’s price-to-earnings (P/E) ratio of around 150 leaves very little margin for operational missteps or unexpected slowdowns in demand.
It is also noteworthy that Palantir’s own outlook implies a deceleration; the midpoint of its full-year 2026 revenue guidance, for instance, equates to 71% growth, which is down from the first quarter’s 85% growth rate. Despite this, CEO Karp recently expressed optimism on CNBC, stating he expects the U.S. business to ‘double again in 2027,’ indicating the company’s strong belief in its future growth potential.
However, valuation discipline remains a critical factor for investors, even for a company executing as well as Palantir has on its top line. With closed TCV growth dropping from 138% to 61% in a single quarter and U.S. commercial RDV growth visibly slowing for three consecutive quarters, the underlying conditions that have powered Palantir’s accelerating revenue trend may face increasing headwinds. Should the company’s top-line growth rate eventually transition from accelerating to decelerating, the financial rationale supporting the current valuation could quickly become untenable, leading many to remain on the sidelines for now.
