A stock usually rises or falls on its own news. You report strong earnings, the shares climb. You miss, they drop. That is the deal investors think they are signing up for.
The artificial intelligence (AI) trade has quietly broken that rule. It now moves in layers. Chipmakers sit at the bottom, the server builders stack on top, and the software companies ride highest of all. When money pours onto one layer, it tends to splash onto the others, whether or not those other companies have said a word.
Palantir Technologies (PLTR) spent most of 2026 learning the painful side of that dynamic. The stock had slid about 12% on the year, dragged down with the rest of the high-multiple software group as investors wondered whether the AI spending boom was cooling.
Then, on Friday, May 29, the shares ripped roughly 10% higher, to near $158. The trigger was not a Palantir press release. It was an earnings report from Dell Technologies (DELL).
How the AI infrastructure stack lifts software names
To understand the move, it helps to start one layer down, at the chips. NVIDIA (NVDA) reported record quarterly revenue of $81.6 billion on May 20, up about 85% from a year earlier and powered by data-center demand, according to a regulatory filing.
More Palantir
NVIDIA chief executive Jensen Huang described the moment as “the largest infrastructure expansion in human history” in that filing.
All of that spending has to land somewhere. Hardware makers turn the chips into finished servers. Software firms turn the servers into tools a bank, a hospital, or a defense agency can actually run.
Palantir sits at that top layer. So when the hardware below it sells out, the case for the software riding on top gets stronger, even on a day when Palantir itself says nothing.

What Dell’s blockbuster quarter means for Palantir
Dell delivered the report that lit the fuse. The company posted fiscal first-quarter revenue of $43.84 billion, up about 88% from a year earlier and well past the roughly $35.4 billion Wall Street expected, according to a company statement. Non-GAAP earnings came in at $4.86 a share, beating the $2.96 consensus by about 64%, CNBC reported.
The detail that mattered most sat inside the server business. Dell’s AI-optimized server revenue jumped 757% from a year earlier to $16.1 billion, and the company booked $24.4 billion in AI orders during the quarter, according to Dell. It also lifted its full-year AI server revenue target to about $60 billion.
Here is the at-a-glance version of the quarter:
-
Total revenue: $43.84 billion, up about 88% year over year.
-
Non-GAAP earnings per share: $4.86 versus a $2.96 consensus, a 64% beat.
-
AI-optimized server revenue: up 757% to $16.1 billion.
-
AI orders booked in the quarter: $24.4 billion.
-
Full-year AI server guidance: raised to about $60 billion.

The AI opportunity “shows no signs of slowing,” Dell Chief Operating Officer Jeff Clarke said.
That report matters for Palantir, because of what the two companies agreed to three weeks ago. At Dell Technologies World on May 18, they unveiled a joint product that puts Palantir’s Foundry and AIP software inside the Dell AI Factory with NVIDIA, according to a company blog post. Palantir’s data layer runs on Dell ObjectScale and PowerFlex storage, aimed at sovereign, defense, and regulated customers who will not put sensitive data in the public cloud.
When I ran Dell’s $24.4 billion in quarterly AI orders against that partnership, the read was simple. Every regulated enterprise buying a Dell AI Factory is now a potential Palantir customer, and Dell just told the market those buyers are lining up.
Snowflake and Gartner fuel the broader software rally
Palantir did not move alone. Software stocks had already caught a bid earlier in the week from Snowflake (SNOW), which reported fiscal first-quarter revenue of $1.39 billion, up about 33%, with product revenue up 34%, according to Business Wire. The data firm raised its full-year product revenue outlook to $5.84 billion and said more than 13,600 accounts now use its AI tools.
Snowflake CEO Sridhar Ramaswamy called the quarter “a clear inflection point” for AI on the platform, according to the same statement. Other software names rode the wave, with Dynatrace (DT) up about 4% on May 29.
The macro backdrop did the rest. Gartner expects worldwide AI software spending to grow about 60% to roughly $453 billion in 2026, part of a total AI spending forecast of $2.59 trillion, according to a research report. For Palantir, a company that sells AI software to large enterprises, that is the tide it wants at its back.
What the Palantir rally means for your portfolio
If you own Palantir, the honest question is whether the jump was a turning point or a one-day rental. The stock trades near 203 times earnings, so the price already assumes years of fast growth. A borrowed catalyst does not change that math.
The bull case is straightforward. The Dell partnership widens the pool of customers who can run Palantir without building their own data center, and the AI infrastructure spending under it is still climbing.
The bear case is just as clear. The move was sympathy buying, and sympathy fades once the excitement around someone else’s earnings cools.
The crowd leaned bullish. Prediction market Polymarket put the odds of Palantir closing the May 29 session higher at about 98%, while sentiment on Reddit’s r/WallStreetBets recovered to a 75 bullish score after a rough start to the week.
In my analysis, the tell to watch is not the May 29 pop but the days after it. If the gains hold into the new week and buyers follow through, the Dell read-through was real. If they leak away, this was a rented rally on a borrowed catalyst.
The next true test is Palantir’s own earnings report. Until then, the stock will trade as a proxy for the AI buildout it sits on top of, rising and falling on numbers that, like this week’s, may not be its own.
