White House pressured US space firms to skip Macron's Paris space summit

Full text

The White House pressured U.S. space companies to skip French President Emmanuel Macron’s space summit in Paris next week — a surprise move that left company executives confused about what they should do.

An official within the White House’s office of science and technology policy told several companies, including SpaceX, Stoke Space, K2 Space and Astra, on a private call Thursday that attending the two-day summit at Paris’ Grand Palais could look like tacit support for EU policy positions, according to two industry representatives and a congressional staffer familiar with the call.

While the White House official emphasized that the decision to attend or not is ultimately up to the companies, the people said it appeared like the administration was discouraging attendance at the event — which is expected to include more than 120 countries. The people were granted anonymity to speak candidly about the call.

The American brushback comes as ties between the U.S. and its European allies are increasingly strained amid fights over tariffs , American troop deployments on the continent and the Iran war. It’s also noteworthy given that Macron and President Donald Trump have historically had a chummy relationship, with the French leader threading the needle between criticizing the American president and provoking his ire.

The Office of Science and Technology Policy official on the call told industry representatives that France did not coordinate with the U.S. on the summit, accused the country of “anti-competitive practices,” and suggested the event’s panels were not designed to include the American perspective and may diminish U.S. industry efforts, according to the people.

The official on the call also voiced concern about China’s attendance at the symposium, the people said.

Macron’s office did not respond to a request for comment.

The White House’s OSTP, which oversees the nation’s science and tech policy agenda, held the call to get everyone on the same page and answer questions about the U.S. position on the summit, an official at OSTP said, who was granted anonymity to describe the intention of Thursday’s call with industry. The official said the companies were not given marching orders.

“The Trump administration continues to collaborate with allies and partners in space,” the official said. “We look forward to productive conversations at the Space Summit on key priorities including science missions, exploration programs and space security.”

After the call, company executives scrambled to decide if they should still participate or not, according to one of the industry representatives.

“Europe is an important market for U.S. space companies but not as important as America,” one of the representatives said. “U.S. space companies are now in the awkward position of figuring out how to gracefully bow out.”

SpaceX, Stoke Space, K2 Space and Astra did not respond to a request for comment.

Despite the administration’s concerns about the event, officials from OSTP, the State Department, Commerce Department and NASA are still attending the summit.

The summit, set for Sept. 9-10, is expected to bring together delegations from the countries alongside space agencies, industry leaders, scientists and military officials.

The event “aims to promote frank and direct dialogue, as well as outlooks and avenues for work and action through high-level talks, announcements and workshops,” according to a French government website , adding that the goal would be “strategic reflection on the future of space.”

European Commission President Ursula von der Leyen also plans on delivering a major speech at the summit, POLITICO has reported.

The event comes as Europe aims to build up its sovereign space capabilities and reduce its reliance on the U.S. Macron rolled out a new space strategy in November and announced a planned increase of €4.2 billion in military space spending from 2026 to 2030, bringing total military space spending to €10.2 billion.
