Palantir management flags AI labs as new rivals for corporate clients

Palantir Technologies management stated on its second quarter of 2026 earnings call that the shift in AI models the company had warned about for years is now here, positioning large AI model developers as direct competitors for corporate customers. The company reported that a major tech firm tested a rival lab's deployment team against Palantir's AI platform, resulting in a $10 million annual contract for Palantir.

The competition arises because the AI labs that build large models now seek the same business clients that drive Palantir's commercial growth. Palantir uses these labs' models, creating a dynamic where suppliers are also rivals. The Information reported on September 14, 2026, that Palantir was among large technology companies potentially restricting or stopping the use of advanced AI models to protect intellectual property from misuse by Anthropic and OpenAI.

Corporate clients supplied 46% of Palantir's revenue in fiscal 2025, totaling $2.1 billion from its Commercial segment. This segment grew 60.0% during the year, outpacing the 53.1% growth in the Government segment. The U.S. commercial business is expanding at the fastest rate, with revenue reaching $764 million in the second quarter of 2026, a 149% increase from the prior year. Management forecasts U.S. commercial revenue of more than $3.424 billion for 2026, implying growth of at least 134%.

Palantir's stock performance reflects high expectations for continued rapid expansion. The shares returned 46% over the three months through October 5, 2026, compared to a 3.9% gain for the S&P 500. Investors currently pay approximately $74 for each dollar of Palantir's sales over the past twelve months, significantly higher than the $3 multiple for the S&P 500. The stock trades about 9% below its 52-week high, suggesting the market assumes these new rivals will not hinder Palantir's growth trajectory.

Current customer metrics show no immediate signs of loss to these competitors. Palantir reported 653 U.S. commercial customers at the end of the second quarter of 2026, up 35% year-over-year. The company signed U.S. commercial contracts worth $2.132 billion in that quarter, a 153% increase from the previous year. However, historical volatility remains a risk; Palantir stock fell 63.8% from peak to trough during the 2022 inflation shock, whereas the S&P 500 declined 24.5%.

Investors will look to third quarter results for further clarity. Management forecasts revenue between $2.16 billion and $2.164 billion for the quarter, up from $1.935 billion in the second quarter. The full-year forecast of at least 134% U.S. commercial growth implies a slowdown from the second quarter's 149% pace. A sharper deceleration could indicate that AI labs are gaining ground, though revenue figures alone would not reveal the underlying cause.
