Palantir's Valuation Surge: Is the AI Giant Overhyped or Undervalued?

The recent 30% surge in Palantir Technologies (NASDAQ: PLTR) following a $10 billion U.S. Army contract win has reignited debates about its valuation. While the stock has since retreated 18% from its post-earnings peak, the company's trajectory raises a critical question: Is Palantir's sky-high price-to-sales (P/S) ratio of 92.6x a sign of overhyped speculation, or does it reflect a justified bet on its transformation into an enterprise AI platform?

The Government Contract Catalyst

Palantir's Q2 2025 results were a masterclass in strategic positioning. U.S. government revenue surged 53% year-over-year to $426 million, driven by contracts like the Maven Smart System (MSS) extension and a $10 billion Army deal. These contracts, with their long-term, high-margin nature, provide a stable revenue runway. The remaining deal value (RDV) for U.S. government contracts now stands at $2.79 billion, a 145% YoY increase. This durability is a stark contrast to the volatility of commercial SaaS models, where churn and pricing pressures often dominate.

However, the market's initial euphoria was short-lived. Despite record revenue of $1 billion and a 94 Rule of 40 score (a metric combining growth and profitability), the stock plummeted 25% post-earnings. The disconnect highlights a key tension: Palantir's valuation is priced for perfection. At a trailing P/E of 516.70 and an EV/EBITDA of 610.40, the stock demands that the company sustain hypergrowth while navigating political risks (e.g., budget cycles) and competitive threats from AI-native startups.

Historically, however, PLTR has shown strong post-earnings momentum. A backtest from 2022 to now reveals a 100% win rate over 3 and 10 days, with a 66.67% win rate at 30 days, and a maximum return of 21.62% over 30 days. This pattern suggests that, while the recent 25% drop defies the norm, the stock has historically experienced upward pressure following earnings releases.

Contrarian Valuation Analysis

To assess whether Palantir is overbilled or undervalued, one must compare its P/S ratio to peers. As of Q2 2025, Palantir's P/S of 92.6x dwarfs Snowflake's 15.5x and Databricks' implied 16.76x (based on its $62 billion valuation and $3.7 billion ARR). Even AI-focused startups like xAI, valued at 150x revenue, appear more “rational” by comparison. This disparity suggests the market is pricing Palantir not just for its current performance but for its potential to dominate the $1.5 trillion enterprise AI market—a sector projected to grow at 25% annually through 2030.

Yet, such multiples ignore a critical flaw: Palantir's business model lacks the subscription stickiness of SaaS darlings. While its government contracts offer durability, they are subject to political whims and budget constraints. Meanwhile, its commercial segment—though growing 93% YoY to $306 million—remains a small portion of total revenue. This duality creates a valuation paradox: Palantir is both a cash-generative government contractor and a speculative AI platform, yet the market treats it as a single entity.

The AI Sector's Contradictions

The broader AI sector is in a bubble, with startups like Decagon and xAI securing 150x revenue multiples despite minimal ARR. This frenzy contrasts with Palantir's grounded approach: its AI tools are embedded in real-world operations (e.g., military logistics, cybersecurity), not just pilot projects. CEO Alex Karp's emphasis on “ontology-based systems” that integrate data silos into actionable insights gives Palantir a defensible edge in mission-critical applications.

However, the company's reliance on government contracts introduces risks. For instance, a shift in administration priorities or a slowdown in defense spending could disrupt its revenue stream. Conversely, its commercial AI expansion—though nascent—could unlock new growth. The challenge lies in balancing these two pillars without overextending.

Investment Implications

For contrarians, Palantir's valuation appears unsustainable. At 92.6x sales, the stock assumes a 100% success rate in scaling its commercial AI offerings and maintaining government dominance—a tall order in a sector prone to disruption. Short-sellers like Citron Research argue that Palantir's lack of a recurring revenue model and its exposure to political risks justify a lower multiple.

Yet, for long-term investors, the company's 57% free cash flow margin and $6 billion in cash reserves offer a buffer against volatility. Its government contracts, with their high switching costs and long-term RDV, provide a moat that few AI startups can match. Moreover, the AI sector's inevitable correction may create buying opportunities for those who believe in Palantir's dual-track strategy.

Conclusion

Palantir's valuation surge is a tale of two narratives: one of speculative optimism and another of strategic resilience. While its P/S ratio appears extreme, the company's unique position in government AI and its ability to convert revenue into cash flow justify a portion of its premium. However, investors must weigh the risks of overvaluation against the potential for sustained growth. In a sector where hype often outpaces reality, Palantir's blend of enterprise AI and government contracts may yet prove to be a defensible bet—but only for those with a long-term horizon and a tolerance for volatility.
