Why Palantir (NASDAQ:PLTR) Is Rallying on Its Nvidia Deal Even Though the Stock Isn’t Cheap Yet

KEY POINTS

  • Palantir (NASDAQ:PLTR) jumped about 8% on 1 July and kept rising on 2 July, trading near US$130.
  • The catalyst is a new partnership with Nvidia to build secure "sovereign AI" for US government agencies.
  • The deal has no disclosed dollar value, so the rally is about positioning, not confirmed revenue.
  • Even after the bounce, the stock is still down for 2026 and trades at a very high valuation.

Palantir (NASDAQ:PLTR) has been one of the market’s brighter spots this week, jumping about 8% on 1 July and climbing further on 2 July to trade near US$130. The driver is a new partnership with Nvidia. But here is the catch: even after this rally, the stock is still down for the year and looks far from cheap. So what is the deal, and is it worth buying? Here is our read.

What Is the Palantir-Nvidia Deal?

Palantir and Nvidia are teaming up to deliver what they call “sovereign AI” for US government agencies and critical infrastructure. In plain terms, they are combining Nvidia’s AI models with Palantir’s software so that sensitive government bodies can run powerful AI tools inside secure, sealed-off systems without their private data ever leaving their control.

That is a genuinely valuable idea. Governments want the power of modern AI but cannot risk secret data leaking into public systems. This partnership aims to solve exactly that. One important detail, though: the companies did not attach a dollar figure to the deal. It is a strategic tie-up, not a signed contract with guaranteed revenue.

Why the Stock Jumped, and Why That’s a Bit Surprising

If there is no fixed revenue attached, why did Palantir add billions in value in a day? The answer is positioning. Investors have been rotating out of AI chip makers and into AI software companies, and a credibility boost from Nvidia, the biggest name in AI, made Palantir the obvious winner of that shift.

Here is the telling part: Nvidia’s own shares did not rise on the news. That tells you this was less about the deal’s direct profits and more about sentiment finally turning back in Palantir’s favour after a rough few months. It is worth remembering the stock fell sharply earlier in 2026, so some of this move is simply recovery from an oversold level.

The Investor’s Takeaway: Buy or Wait?

Here is the honest part. Palantir is a genuinely strong business. It posted 85% year-on-year revenue growth in the first quarter of 2026 and raised its full-year revenue guidance to roughly 71% growth. But even at that blistering pace, the stock trades at more than 140 times trailing earnings, an extremely high price that leaves little room for error, and it remains well below its 52-week high of about US$207.

For believers in Palantir’s government AI story, this partnership strengthens the long-term case, and the pullback may still offer an entry. For more cautious investors, a stock this expensive, rallying on a deal with no disclosed value, is one to watch rather than chase.

The real test comes at the next earnings report, which will show whether deals like this one turn into actual contracts. The story is improving, but the price already assumes a lot will go right.
