What Could Go Wrong With Palantir Stock?

Palantir Technologies (PLTR) turned 42.8% of its sales into operating profit over the past twelve months. A year earlier that figure, the operating margin, was 16.6%. The margin matters because holders pay 151.2 times earnings for the stock, against 21.4 for the S&P 500. At that price, holders have a lot to lose if profit slips. What lifted Palantir’s margin that far in a single year?

Palantir Lifted Its Margin As Sales Outgrew Costs

Palantir’s margin rose because its sales grew much faster than its costs. Revenue over the past twelve months was $6.2 billion, up from $3.4 billion a year earlier.

Palantir makes most of its sales in its U.S. business, now over 81% of total revenue. On the fiscal Q2 2026 call, management said U.S. revenue grew 115% in the quarter from a year earlier. Management also said companies are showing immense demand for sovereign AI, meaning AI they fully control.

Palantir’s margin is now far higher than it was in recent years. Three years ago Palantir made an operating loss equal to 3.2% of sales. Today’s 42.8% is the highest in five years.

What Could Go Wrong With Palantir’s Margin?

Costs could start to grow faster than sales. On the same call, management told investors to expect a significant rise in expenses in fiscal Q3 2026. The reasons it gave were the seasonal timing of new hire starts and spending on product and marketing.

One cost has already risen. Palantir took on cloud hosting for one of its government customers in fiscal Q2 2026. Management said the change led to a higher cost of revenue in the quarter.

If the margin fell, Palantir would make less profit on the same sales. The stock trades at 151.2 times its earnings. The price likely assumes that the margin stays near today’s level.

In the past, Palantir stock has fallen much harder than the market. In the 2022 inflation shock it fell 64.0% from peak to trough, against 24.0% for the S&P 500.

What Is Still Going Right At Palantir?

Sales growth is still speeding up. Revenue grew 92.8% from a year earlier in the latest quarter, up from 62.8% three quarters before. Growth rose in every quarter along the way.

Management has also raised its forecast. Palantir now expects full-year 2026 revenue of $8.15 billion to $8.158 billion, and management called the change its largest-ever raise.

Palantir reports its third quarter of 2026 next. Management forecast adjusted operating profit of $1.292 billion to $1.296 billion on revenue of about $2.16 billion. That is about 60% of revenue, down from 62% in the second quarter, so management itself expects the margin to dip as expenses rise. The adjusted figure leaves out some costs, so it should not be set against the 42.8% reported margin

For now, the margin is a risk for holders to watch, not a problem, because sales are still accelerating. The risk would become a problem if hiring and hosting costs began to grow faster than sales. Adjusted income from operations within or above the guided range would suggest that Palantir absorbed those costs as management planned. A result below that range would be the first sign that Palantir’s costs are rising faster than management expected.
