Palantir Technologies Inc. (NYSE: PLTR) reported first-quarter revenue of $1.63 billion, an 85% year-over-year surge, though growth in its closely watched US commercial segment failed to meet the most bullish expectations.
The company's US commercial revenue increased 133% from a year earlier, a slight deceleration from the prior quarter's 137% and below some market forecasts for growth exceeding 140%. Total contract value (TCV) growth also slowed to 61% year-over-year, indicating a potential slowdown in new large-scale deals.
Palantir raised its full-year revenue forecast to over $7.6 billion. However, the new guidance implies a growth rate of 71% for the year and around 79% for the second quarter, a slowdown that may concern investors given the stock's high valuation.
Q1 2026 by the Numbers
While the headline revenue number beat expectations, the focus remains on the sustainability of its commercial growth. The US government segment, Palantir's traditional stronghold, continued to show strength with growth of over 84%, bolstered by contracts with the Department of Defense and new agreements with agencies like the Department of Agriculture.
Forward-looking indicators presented a mixed picture. Remaining performance obligations (RPO), which represent future revenue under contract, grew a strong 134% year-over-year. However, the 61% growth in total contract value (TCV) marked a continued deceleration, suggesting new contract signings were heavily weighted toward government deals with longer, more locked-in terms. The company added 53 net new customers in the quarter, 44 of which were in the US commercial space.
The guidance, while raised, suggests a decelerating growth trajectory, putting pressure on the company to maintain momentum in its high-value US commercial contracts. Investors will be closely watching the next earnings report for signs of re-acceleration in new customer acquisition and contract value.
