TLDR
- Palantir and Anduril are developing software for Trump’s $185 billion Golden Dome antimissile shield
- The consortium aims to test the software this summer
- The project’s cost rose $10 billion to $185 billion to accelerate space-based capabilities
- Lockheed Martin, RTX, and Northrop Grumman are already on board as prime contractors
- Successful delivery could open the door to billions in long-term maintenance contracts for Palantir
Palantir Technologies (PLTR) and defense tech firm Anduril Industries are part of a growing consortium building software for the U.S. government’s Golden Dome antimissile shield, the Wall Street Journal reported on Tuesday. PLTR stock climbed 1.25% in after-hours trading on the news.

The Golden Dome project is designed to create a space-based defense layer capable of intercepting ballistic, cruise, and hypersonic missiles. Hundreds of companies are competing for a slice of the work.
Palantir and Anduril have been circling Golden Dome since early on. Reuters reported last year that both firms were already working alongside Elon Musk’s SpaceX on parts of the project.

Also in the software consortium are networking company Aalyria Technologies, AI startup Scale AI, and software firm Swoop Technologies. None of the companies immediately responded to requests for comment.
The timeline is tight. The group is targeting a software test this summer, which puts real pressure on delivery.
Anduril had already secured a foothold in the program — it was among companies awarded small Golden Dome contracts back in November to build competing missile defense prototypes.
What’s at Stake for Palantir
If the software passes muster, the upside could be substantial. Developers like Palantir stand to earn billions maintaining the system over time, giving the contract long-tail revenue potential well beyond the initial build.
That matters for a company still leaning heavily on government work. In 2025, 54% of Palantir’s $4.5 billion in total revenue came from its Government segment, with Commercial making up the remaining 46%.
The project’s price tag has also grown. The program’s director, General Michael Guetlein, said last week that Golden Dome’s cost rose by $10 billion to $185 billion, driven by efforts to ramp up space-based capabilities.
Lockheed Martin, RTX, and Northrop Grumman joined the program earlier as prime contractors, so Palantir and Anduril are entering a project that already has some big names attached.
Where PLTR Stands
PLTR stock is down about 13% year-to-date, though it’s still up roughly 60% over the past 12 months.
Wall Street currently holds a Moderate Buy consensus on the stock, based on 14 Buy ratings, four Holds, and two Sells.
The average analyst price target sits at $194.61, implying around 26% upside from current levels.
