Palantir Technologies delivered its most impressive quarterly performance since going public in 2020, yet the stock has lost more than 22% year-to-date and continued retreating after the results landed, a disconnect that encapsulates one of the most hotly contested valuation arguments in the current market.

The company posted Q1 2026 revenue of $1.63 billion, up 85% year-over-year, marking the 11th consecutive quarter of accelerating revenue growth and extending a beat-and-raise streak that now spans eight straight reports.

US commercial revenue climbed 133% year-over-year to $595 million, driven overwhelmingly by adoption of the company’s Artificial Intelligence Platform. US government revenue grew 84% to $687 million, accelerating from 66% growth in the prior quarter.

CEO Alex Karp said on CNBC that AIP demand is so strong the company is currently unable to keep pace with requests from American customers, a capacity constraint that most businesses would envy. Adjusted EPS of $0.33 beat the $0.28 consensus by a meaningful margin, and net income nearly quadrupled year-over-year to $870 million.

Despite the numbers, the market’s reaction was a sustained slide. The stock fell approximately 7% in the days following the report and is now trading around $135, well below its 52-week high of $207.52 set in November 2025. Polymarket traders had priced in a 99% probability of a down day immediately after earnings dropped, reflecting how fully the market had internalised the narrative that strong results alone are not enough to move the stock higher at current valuation levels.

Truist Securities analyst Arvind Ramnani maintained a Buy rating with a price target of $223, describing the quarter as delivering another significant beat-and-raise and reinforcing Palantir’s positioning as “a critical infrastructure layer for enterprise AI.” Ramnani pointed out that PLTR’s revenue growth has now accelerated for 11 consecutive quarters at a time when the median software company is decelerating into mid-teens growth, and that Palantir has expanded its operating margin by approximately 35% over that same period versus an estimated 23% for its software peers.

The bull case also draws on forward-looking contract metrics. Total remaining deal value reached $11.8 billion, up 98% year-over-year. The company closed 206 deals of at least $1 million in Q1, up from 180 in Q4 and 139 in the same period a year ago. Net revenue retention improved to 150% from 139% previously. D.A. Davidson analyst Gil Luria, despite maintaining a cautious stance on valuation, described these as indicators that growth has not yet peaked, noting that NRR of 150% does not yet reflect the acceleration from newly signed US commercial customers.

The sceptical camp is focused on one number above all others: the price-to-sales ratio, which even after the year-to-date decline sits in the mid-to-high 40s on a forward basis using management’s 2026 guidance. Benchmark analyst Yi Fu Lee initiated coverage with a Hold, saying the “market has priced Palantir for perfection, leaving little to no room for margin of error,” and cautioning that the stock requires “hyper” annual revenue growth of 70% to 80% or more for the foreseeable future just to justify its current price. That is precisely the growth rate management is guiding toward, which means there is essentially no buffer if anything goes wrong.

The full-year 2026 guidance midpoint of $7.655 billion implies 71% growth, a deceleration from the 85% rate just delivered. That alone gives mathematically minded investors reason for caution even in a good quarter. CEO Alex Karp has made the counterargument that Palantir is not a model provider competing in the AI commoditisation race but an applications-layer platform delivering measurable outcomes to governments and enterprises, and that distinction warrants a sustained premium. Whether the market agrees will likely depend on whether the US commercial growth rate, which has accelerated for three quarters running, can hold above triple digits into the second half of the year.
