Both Palantir Technologies Inc. [NASDAQ: PLTR] and BigBear.ai Holdings Inc. [NYSE: BBAI] operate in the AI and defence technology space, both rely heavily on US government contracts, and both attract significant investor attention as pure-play AI names, but a closer look at their quarterly revenue trends reveals a widening fundamental gap between the two companies.

Palantir has delivered a series of increasingly large quarterly revenue beats, with first-quarter 2026 revenue jumping 85% year-over-year to $1.63 billion, driven by 84% growth in US government revenue and a more-than-doubling in US commercial revenue as demand for its AI Platform accelerated across both public and private sector customers.

Management guided for second-quarter 2026 revenue of approximately $1.8 billion, maintaining a trajectory of consistent quarter-over-quarter growth that analysts at Citi and elsewhere describe as among the most reliable in large-cap enterprise software.

The key to Palantir’s visibility is the depth of its contracted pipeline, with the company’s Remaining Deal Value, the total value of unfulfilled contracts, expanding substantially as pilot programmes convert into larger multi-year enterprise agreements with both government agencies and commercial clients.

Full-year 2026 revenue consensus sits at 40% growth, a figure Palantir has repeatedly exceeded in recent quarters, meaning actual results are likely to track materially ahead of that baseline if the current momentum is sustained.

BigBear.ai tells a starkly different story, with revenue declining 1% year-over-year in Q1 2026 to $34.4 million, extending a pattern of year-over-year declines that characterised the company throughout 2025, despite operating in the same structurally high-demand AI environment as its larger peer.

The disconnect is not explainable purely by scale, since demand for AI technology is demonstrably high across the government sector and BigBear.ai has access to the same customer base as other defence AI contractors, suggesting the decline reflects competitive and product-level factors rather than market conditions alone.

On the positive side, BigBear.ai’s gross margin improved significantly in Q1, rising to 34.0% from 21.3% in the prior year, driven by increased contribution from Ask Sage’s higher-margin generative AI platform and products, suggesting the company’s revenue mix is improving even if the top line is not.

Full-year 2026 revenue is projected to grow approximately 23%, and consensus expects the company to begin narrowing its per-share losses, but those projections still leave BigBear.ai generating revenue at roughly one-fiftieth of Palantir’s scale, with a far less proven commercial growth engine.

From a valuation standpoint, Palantir’s elevated price-to-sales ratio of more than 60 times reflects the market’s confidence in its durable growth compounding, while BigBear.ai’s lower comparable multiple reflects the lack of consistent top-line momentum that would justify a premium.

The revenue trend analysis offers a clear conclusion: Palantir is capturing customer spending at scale across both government and commercial markets, while BigBear.ai has yet to demonstrate the product-market fit necessary to generate consistent growth in an environment where AI infrastructure demand is at record levels.
