Rocket Lab (RKLB), SpaceX (SPCX), And AST SpaceMobile (ASTS) Slide Despite Historic FAA Deregulation Push

Space stocks sold off sharply this week even as the FAA unveiled a sweeping proposal to strip away environmental red tape for rocket launches.

The Federal Aviation Administration proposed waiving requirements under 13 federal environmental laws for qualifying launch and reentry licenses, a move the Department of Transportation framed as a major step toward accelerating commercial spaceflight.

That list of targeted regulations includes portions of the National Environmental Policy Act, the Endangered Species Act, and the Clean Water Act, while reviews tied to public safety, national security, and foreign policy would remain intact.

The deregulation push arrives nearly a year after President Donald Trump signed an executive order entitled “Enabling Competition in the Commercial Space Industry,” directing Transportation Secretary Sean Duffy “to eliminate or expedite” environmental reviews for space launch and reentry licenses.

Despite the policy tailwind, Rocket Lab (RKLB) shares fell 9% on Tuesday, July 28, to $60.63, while AST SpaceMobile (ASTS) dropped 7% to $54.09, and SpaceX (SPCX) slipped 3% to $109.96.

The gap between a business-friendly regulatory announcement and a broad-based selloff reveals what is actually driving valuations across the space sector right now.

Rocket Lab builds and flies small and medium rockets, and it recently applied to the FAA for a launch window running from July through year-end for Neutron, its new medium-lift rocket, after a fuel tank ruptured during testing in January.

A faster environmental review process removes one bureaucratic hurdle for Neutron, but it does nothing to resolve the underlying manufacturing challenge the company is still working through following that rupture.

AST SpaceMobile holds no launch license of its own, meaning its stake in the FAA proposal is largely indirect, with the company depending on SpaceX’s Falcon 9 to stay on schedule for a planned launch of three more BlueBird satellites in early August.

SpaceX dominates the launch market and also operates Starlink, still its primary revenue source, and at its scale, environmental reviews have rarely managed to slow operations for long, making the rule change less transformative for it in relative terms.

The proposal now enters a 30-day public comment period before the FAA decides whether to finalize it, meaning nothing changes operationally for any of these companies in the near term.

Blue Origin, SpaceX’s closest competitor in heavy launch, would also benefit from the same rule change if it is eventually finalized, broadening the potential industry impact beyond the three companies that saw their shares fall this week.

Investor attention appears fixed on a different calculus entirely, namely the enormous capital flows reshaping the sector, led by SpaceX’s $75 billion initial public offering in June, the largest on record.

Six members of Congress disclosed purchases of SpaceX stock during the same week as the broader selloff, a notable signal of institutional confidence that ran counter to the market’s direction.

The FAA’s proposal, if finalized, will reduce a real and tangible cost for launch operators across the industry, but as this week’s market reaction made clear, regulatory speed alone will not determine which companies ultimately succeed.
