Four American space companies have pulled out of President Emmanuel Macron's high-profile space summit in Paris days before it opens, after the Trump administration leaned on them to stay away. SpaceX, Blue Origin, Stoke Space and Starcloud each informed the French space ministry on Thursday that they were cancelling their participation in the 9-10 September event, according to a ministry official.

The companies and the timeline

The withdrawals came in a single day. Elon Musk's SpaceX, Jeff Bezos's Blue Origin, rocket developer Stoke Space and Starcloud, a startup pursuing orbital data centres, all notified French authorities they would not attend. The French official confirmed the four names to POLITICO, adding that other US companies still plan to take part. The summit was meant to showcase European launch capability and the IRIS² multi-orbit satellite constellation, a flagship project intended to reduce dependence on foreign communications infrastructure.

White House pressure and the EU Space Act

POLITICO reported earlier this week that the White House had pressed US firms to boycott the gathering. The friction centres on the European Commission's proposed EU Space Act, a regulatory framework Washington argues would impose European rules on American operators and favour domestic champions. The US lobbying effort mirrors a broader pattern: the administration has opposed multilateral initiatives from climate accords to the World Health Organization, while resisting European moves to lessen reliance on US technology.

A Franco-German push to allocate more mobile-satellite spectrum to European operators, including the IRIS² network, has further irritated Washington. For Brussels, Paris and Berlin, the goal is strategic autonomy: ensuring European satellite connectivity does not depend entirely on Starlink or other US providers. From the American perspective, the manoeuvre looks like regulatory protectionism designed to build European champions at US expense.

Macron's space ambitions and European independence

The summit is a personal priority for Macron, who has made space sovereignty a pillar of his European agenda. He wants France and the EU to retain credible independent launch capacity and a sovereign satellite communications system. The event was designed to bring together national delegations, space agencies, industry leaders, scientists and military officials to advance that vision. The absence of four major US players, particularly SpaceX, the dominant launch provider, and Blue Origin, a key competitor, weakens the industry turnout and the diplomatic signal Macron hoped to send.

French and industry reactions

French authorities initially tried to minimise the threat, insisting US companies remained welcome. Behind the scenes, however, six French and space industry officials told POLITICO they were not surprised. One space company official attending the summit described it as a classic Trump tactic: belittling Europeans and Macron in particular, who they said embodies European leadership in the US president's view. The French ministry official struck a resigned tone, acknowledging the pressure while vowing to continue working with American partners despite the complications.

The broader geopolitical context

Several officials argued the US move would backfire by accelerating European diversification. One space official said the silver lining was a push to broaden partnerships globally and invest in domestic industry, framing it not as decoupling but as prudent risk management. Another noted that any gap left by American firms would be filled by other powers, China foremost among them. Christophe Grudler, a French MEP who worked on the EU Space Act, put it bluntly: the Trump administration's mood makes Chinese and other actors appear more likable partners.

Limited immediate impact, longer-term shift

Two industry officials told POLITICO the boycott's practical effect on the summit would be limited. The World Space Business Week, starting a week later in Paris, still lists major US participants including Starlink and Blue Origin. French officials also argue the hole left by the four companies will be plugged by delegations from other spacefaring nations. But the political signal is clear: Washington is willing to disrupt allied coordination to protect its commercial position in orbit.
