Palantir Technologies [NASDAQ: PLTR] has emerged as one of the most closely watched AI stocks on Wall Street, posting explosive growth in both government and commercial revenue across consecutive quarters.

The company’s first-quarter 2026 results delivered another massive beat, with revenue jumping 85% year-over-year to $1.63 billion, driven by 133% growth in US commercial revenue and 84% growth in US government revenue.

CEO Alex Karp raised full-year revenue guidance from 61% growth to 71%, citing what he described as “erupting” demand, particularly from government agencies and corporations rushing to integrate generative AI into their workflows.

Argus Research described the situation as a “high-class problem,” noting that customer demand is now growing faster than the company can actually deploy its AI software to those customers.

Palantir’s AI-powered platforms, including Gotham, Foundry, Apollo, and AIP, help governments and large organisations analyse vast amounts of data, and the company’s Maven AI platform has been recognised as an official US military programme of record.

A new $300 million Department of Agriculture contract also signalled that Palantir’s reach is expanding well beyond its traditional defence and intelligence customer base.

Despite all of that, the stock fell roughly 7% in the two days following earnings, as traders concluded that sky-high expectations had already been baked into the price.

Palantir entered 2026 trading at a price-to-sales ratio above 100 and still sits at roughly 77 times sales, far above software peers and well inside what analysts have historically described as bubble territory.

History shows no major technology company has sustained a P/S ratio above 30 for an extended period, and Palantir’s valuation leaves almost no margin for error even as the business continues to outperform.

Wall Street analysts remain broadly constructive: Argus Research upgraded the stock to Buy with a $190 target, UBS assigned a $180 target, and Rosenblatt maintained a $200 target citing global defence spending and AI adoption.

Morgan Stanley held its Equal Weight rating, cautioning that much of Palantir’s growth story may already be priced in, and Goldman Sachs flagged similar concerns around valuation multiples.

The consensus analyst price target of $190.88 implies meaningful upside from current levels, but the valuation debate is expected to remain the defining issue around PLTR throughout 2026.
