WASHINGTON -- Elon Musk’s SpaceX and two partners have emerged as frontrunners to win a crucial part of U.S. President Donald Trump’s “Golden Dome” missile defence shield, six people familiar with the matter said.

Musk’s rocket and satellite company is partnering with software maker Palantir and drone builder Anduril on a bid to build key parts of Golden Dome, the sources said, which has drawn significant interest from the technology sector’s burgeoning base of defence startups.

In his Jan. 27 executive order, Trump cited a missile attack as “the most catastrophic threat facing the United States.”

All three companies were founded by entrepreneurs who have been major political supporters of Trump. Musk has donated more than a quarter of a billion dollars to help elect Trump, and now serves as a special adviser to the president working to cut government spending through his Department of Government Efficiency.

Despite the Pentagon’s positive signals to the SpaceX group, some sources stressed the decision process for Trump’s Golden Dome is in its early stages. Its ultimate structure and who is selected to work on it could change dramatically in the coming months.

The three companies met with top officials in the Trump administration and the Pentagon in recent weeks to pitch their plan, which would build and launch 400 to more than 1,000 satellites circling the globe to sense missiles and track their movement, sources said.

A separate fleet of 200 attack satellites armed with missiles or lasers would then bring enemy missiles down, three of the sources said. The SpaceX group is not expected to be involved in the weaponization of satellites, these sources said.

One of the sources familiar with the talks described them as “a departure from the usual acquisition process. There’s an attitude that the national security and defense community has to be sensitive and deferential to Elon Musk because of his role in the government.”

SpaceX and Musk have declined to comment on whether Musk is involved in any of the discussions or negotiations involving federal contracts with his businesses.

The Pentagon did not respond to detailed questions from Reuters, only saying it will deliver “options to the President for his decision in line with the executive order and in alignment with White House guidance and timelines.”

The White House, SpaceX, Palantir, and Anduril also did not respond to questions. After publication, Musk replied to a post about Reuters’ story on his social network X without elaborating: “This is not true.”

Subscription service

In an unusual twist, SpaceX has proposed setting up its role in Golden Dome as a “subscription service” in which the government would pay for access to the technology, rather than own the system outright.

The subscription model, which has not been previously reported, could skirt some Pentagon procurement protocols allowing the system to be rolled out faster, the two sources said. While the approach would not violate any rules, the government may then be locked into a subscription and lose control over its ongoing development and pricing, they added.

Some Pentagon officials have expressed concerns internally about relying on the subscription-based model for any part of the Golden Dome, two sources told Reuters. Such an arrangement would be unusual for such a large and critical defence program.

U.S. Space Force General Michael Guetlein has been in talks on whether SpaceX should be the owner and operator of its part of the system, the two sources said. Other options include having the U.S. own and operate the system, or having the U.S. own it while contractors handle operations. Guetlein did not respond to a request for comment.

Retired Air Force General Terrence O’Shaughnessy, a top SpaceX advisor to Musk, has been involved in the company’s recent discussions with senior defence and intelligence leaders, the two sources said. O’Shaughnessy did not respond to requests for comment.

Should the group led by SpaceX win a Golden Dome contract, it would be the biggest win for Silicon Valley in the lucrative defence contracting industry and a blow to the traditional contractors.

However, those long-standing contractors, such as Northrop Grumman, Boeing and RTX are expected to be big players in the process as well, people familiar with the companies said. Lockheed Martin put up a webpage as a part of its marketing efforts.

Many bids

The Pentagon has received interest from more than 180 companies keen to help develop and build the Golden Dome, according to a U.S. official, including defense startups like Epirus, Ursa Major and Armada. Members of the White House’s National Security Council were briefed by a handful of companies about their capabilities, four sources said.

The Pentagon’s number two, former private equity investor Steve Feinberg, will be a key decision-maker for Golden Dome, two U.S. defence officials said.

Feinberg co-founded Cerberus Capital Management which has invested in the cutting-edge hypersonic missiles industry but not in SpaceX. Feinberg, who did not respond to a request for comment, has said he would divest of all his interests in Cerberus when he joined the administration.

Some experts believe the overall cost for Golden Dome could reach hundreds of billions of dollars. The Pentagon established several timelines for capabilities to be delivered starting with early 2026 to those delivered after 2030.

Laura Grego, research director at the nonprofit Union of Concerned Scientists, questioned the feasibility of such a defence system given that multiple studies have concluded it is a “bad idea, expensive and vulnerable.”

“Such a system could be overwhelmed by launching multiple weapons at the same time, pushing the required size of the defence to very large numbers – potentially in the tens of thousands of satellites,” Grego said.

SpaceX is pitching for the part of the Golden Dome initiative called the “custody layer,” a constellation of satellites that would detect missiles, track their trajectory, and determine if they are heading toward the U.S., according to two sources familiar with SpaceX’s goals.

SpaceX has estimated the preliminary engineering and design work for the custody layer of satellites would cost between US$6 billion and $10 billion, two of the sources said. In the last five years, SpaceX has launched hundreds of operational spy satellites and more recently several prototypes, which could be retrofitted to be used for the project, the sources said.

Reuters reviewed an internal Pentagon memo from Defense Secretary Peter Hegseth issued shortly before a Feb. 28 deadline to senior Pentagon leadership asking them for initial Golden Dome proposals and calling for the “acceleration of the deployment” of constellations of satellites.

The time frame could give SpaceX an advantage because of its fleet of rockets, including the Falcon 9, and existing satellites that could be repurposed for the missile defence shield, the people familiar with the plan said.

Despite these advantages, some of those familiar with the discussions said it was uncertain whether the SpaceX group would be able to efficiently set up a system with new technology in a cost-effective way that can protect the United States from attack.

“It remains to be seen whether SpaceX and these tech companies will be able to pull any of this off,” said one of the sources. “They’ve never had to deliver on an entire system that the nation will need to rely on for its defence.”

Separately, some Democrats in Congress expressed concern about Musk’s bidding on federal contracts while serving in the White House.

“When the richest man in the world can become a Special Government Employee and exert influence over the flow of billions of dollars of taxpayer money in government contracts to his companies, that’s a serious problem,” said U.S. Senator Jeanne Shaheen, a senior member of the Armed Services Committee.

Shaheen has introduced new legislation that would prevent federal contracts from being issued to companies owned by any special government employee like Musk.

U.S. Rep. Donald Beyer told Reuters he was also concerned about SpaceX’s role given Musk’s unprecedented “inside access to non-public information and data.”

“Any contracts awarded to him, or his companies, are suspicious,” he said.
