Better Artificial Intelligence (AI) Stock: Palantir vs. BigBear.ai

A comparative analysis of AI software companies Palantir Technologies (PLTR) and BigBear.ai (BBAI) favors Palantir as the stronger investment, despite its premium 115x sales valuation. Palantir demonstrated significant momentum with a 43% YoY increase in customer count and 64% growth in $1M+ deals, projecting a 45% revenue spike and 57% EPS jump for 2025, underpinned by tangible customer productivity gains. In contrast, BigBear.ai, while trading at a lower 9x sales and possessing a growing backlog, experienced an 18% Q2 revenue decline and lowered 2025 guidance due to its volatile government contract dependency, making its growth trajectory less reliable.

Analysis

A comparative analysis of Palantir (PLTR) and BigBear.ai (BBAI) reveals a significant divergence in fundamental performance and risk, despite both operating in the high-growth AI software sector. Palantir demonstrates robust operational momentum, with its customer count increasing 43% year-over-year in Q2 2025 and the number of deals valued over $1 million growing even faster at 64%. This operational success is translating into strong financial forecasts, including a projected 45% revenue spike for 2025 and a 57% increase in earnings per share. While its 115x price-to-sales ratio is notably high, it is supported by tangible evidence of customer value, such as dramatically reducing fraud detection times for Fannie Mae. Conversely, BigBear.ai presents a more speculative case. Despite a seemingly attractive 9x sales multiple and a 43% YoY increase in its backlog to $380 million, the company's Q2 revenue declined 18% YoY to $32.5 million. More critically, BigBear.ai lowered its 2025 guidance to $132.5 million, below the previous year's $158 million, citing an inability to convert Army contracts. This highlights a critical business risk tied to its heavy reliance on volatile government contracts, making its growth trajectory far less certain than Palantir's.

Key Decisions for Investors

• Investors should view Palantir's premium 115x sales valuation in the context of its accelerating growth metrics, including a 43% customer increase and a 64% jump in large deals, which suggest the market is pricing in sustained, high-quality execution.
• Caution is warranted for BigBear.ai, as its low valuation appears to be a value trap given the 18% Q2 revenue decline, a downward revision of full-year guidance, and significant concentration risk tied to unreliable government contract conversions.
• For direct exposure to the AI software theme, the evidence suggests favoring Palantir's proven commercial traction and strong forward guidance over BigBear.ai's speculative turnaround story, which hinges on its ability to resolve fundamental business model vulnerabilities.
