Palantir Technologies Inc. (PLTR) and ServiceNow, Inc. (NOW) both sell software that helps large organizations put data and AI to work. Yet after two turbulent trading sessions, investors were valuing Palantir at more than four times ServiceNow, even though ServiceNow expects nearly twice as much subscription revenue as Palantir expects in total sales.

The roughly $333 billion valuation gap raises a question about what Wall Street believes Palantir can become.

Two Days Changed the Valuation Gap

On Oct. 28, ServiceNow's market capitalization stood at $155.82 billion, compared with Palantir's $472.91 billion. By Oct. 30, ServiceNow's value had fallen nearly 30% to $109.11 billion. Palantir also declined, but by a more modest 6.5%, to $442.40 billion.

That widened Palantir's valuation premium from 3.03 times ServiceNow to 4.05 times in just two sessions. The gap between their market values reached roughly $333 billion.

The sell-off followed ServiceNow's Oct. 28 earnings. The company reported third-quarter revenue of $4.106 billion, up 20.5% year over year, and raised its 2026 subscription revenue outlook to $15.78 billion-$15.79 billion. But its fourth-quarter forecast for current remaining performance obligations, or contracted revenue expected over the next 12 months, implied 18.5% growth, below the 20.5% growth it reported for the third quarter.

That softer forward indicator appears to have unsettled investors despite the beat-and-raise quarter.

Palantir's Growth Is the Premium

Palantir's latest reported quarter offered a very different growth profile. Revenue climbed 93% year over year to $1.94 billion in the second quarter, while U.S. commercial revenue surged 149%. The company also reported a 62% adjusted operating margin and raised its 2026 total revenue forecast to $8.15 billion-$8.158 billion.

That growth helps explain why investors assign Palantir a much richer valuation. Its Artificial Intelligence Platform (AIP) helps organizations connect AI models to proprietary data and operational workflows, while its government and commercial businesses give it exposure to high-stakes applications.

Investors are effectively paying for the possibility that rapid adoption, expanding contracts and high margins can compound for years. Its third-quarter earnings report after market close on Monday will provide more insight into the company's progress.

The $333 Billion Question

The revenue comparison needs context. ServiceNow's $15.78 billion-$15.79 billion forecast covers subscription revenue alone; Palantir's $8.15 billion-$8.158 billion outlook covers total revenue. They are not like-for-like measures, and the companies serve overlapping but distinct enterprise software needs.

ServiceNow also has substantial momentum: its third-quarter current remaining performance obligations reached $13.65 billion, up 20.5%, and it raised its 2026 AI annual contract value target to $1.7 billion.

The valuation gap does not prove Palantir is overvalued or ServiceNow is undervalued. It shows how heavily investors are rewarding Palantir's faster growth and profit profile, and how quickly sentiment can change when forward expectations disappoint.
