Palantir Technologies: Soaring AI Star or Bubble Ready to Burst?

Palantir Technologies ( (PLTR) ) has been popular among investors this week. Here is a recap of the key news on this stock.

Palantir Technologies is delivering eye‑catching growth that is reshaping how investors view the AI and defense software space. Revenue has accelerated for 10 straight quarters, surging 70% year over year in Q4 to $1.41 billion, while its Rule of 40 score hit an extraordinary 127%, far above typical elite software peers. Much of this momentum stems from its Artificial Intelligence Platform, with U.S. commercial revenue soaring 137% and management guiding to about $7.2 billion in 2026 sales.

The company is positioning itself as the operating system for both modern warfare and critical industries, driving optimism that it could become a “Microsoft of the AI era.” Yet this operational success comes with a lofty price tag. Even assuming rapid EPS growth through 2028, Palantir still trades at an estimated 53x earnings in three years, leading some observers to stay neutral and wait for a better entry point.

Wall Street is broadly constructive despite valuation worries. The stock carries a Moderate Buy consensus based on a majority of Buy ratings, and the average 12‑month price target of about $191 suggests roughly 40%+ upside from current levels. Mizuho upgraded Palantir to Outperform after a 24% year‑to‑date pullback, arguing the recent multiple compression has made the risk‑reward “newly attractive” while both commercial and government demand remain robust.

Not everyone is convinced the story is sustainable. Michael Burry has launched a highly public short thesis, warning that Palantir’s valuation is disconnected from fundamentals and could fall as much as 66%, and he has also questioned its accounting choices and corporate culture. Technical traders note a head‑and‑shoulders pattern on the chart that may signal further downside, highlighting the growing divide between the bull case around long‑term AI infrastructure and the bear case focused on near‑term overvaluation.

At the same time, Palantir is deepening its ecosystem through new partnerships. A high‑profile deal with Rackspace Technology will see Rackspace help enterprises deploy Palantir’s Foundry and AI Platform more quickly, including in private and sovereign clouds for heavily regulated industries. For investors, Palantir now represents a high‑conviction AI infrastructure play with exceptional growth, but also one where expectations are so elevated that even small disappointments could trigger sharp volatility.
