SpaceX’s decision to wind down Falcon 9 commercial operations is reshaping the competitive landscape for space stocks heading into September 2026.
AST SpaceMobile (ASTS), Rocket Lab (RKLB), SpaceX (SPCX), and Intuitive Machines (LUNR) are each positioned differently as Falcon 9 capacity shifts away from commercial payloads.
LUNR has led the group in August with a 35% gain, followed by SPCX at 27%, FLY at 9%, ASTS at 5%, and RKLB at 3%.
SpaceX completed its last Falcon 9 Starlink mission from Florida on Tuesday, marking a significant transition toward Starship-led East Coast operations.
SpaceX Vice President of Launch Kiko Dontchev confirmed the milestone on X, saying “This morning’s @SpaceX mission from pad 40 was the last planned Falcon 9 Starlink launch from Florida,” calling it “the end of an era.”
CEO Elon Musk said Falcon will be wound down “once Starship is flying reliably several times per week,” freeing up what he called “super scarce” resources to achieve multiple Starship launches per day.
Falcon 9 is on pace for 155 missions in 2026, down from its record of 165 in 2025, while the rocket will continue supporting Crew Dragon, NASA, and national-security missions.
Rocket Lab’s Neutron rocket, designed to carry 13 to 15 metric tons into low Earth orbit, is directly targeting the medium-lift gap that Falcon 9’s commercial wind-down will create.
Rocket Lab’s backlog reached a record $2.36 billion in the second quarter, up 137% from a year ago, with more than 90 launches already under contract including a Kepler Communications flight no earlier than 2028.
Firefly Aerospace is pursuing the same commercial opening, with its Alpha Block 2 rocket targeting a fourth-quarter debut and most of its 2027 manifest already sold.
Firefly’s Northrop Grumman-backed Eclipse medium-lift rocket, designed to carry 16 metric tons to low Earth orbit, is targeting its first flight in 2027, adding further competitive weight to the mid-size launch segment.
Firefly CEO Jason Kim has called launch capacity “the most constrained I’ve ever seen,” a view that aligns with KeyBanc Capital Markets’ June assessment that the market could remain undersupplied for more than a decade.
KeyBanc had upgraded both Rocket Lab and Firefly to “Overweight,” citing the likelihood that Starship’s early capacity would largely serve SpaceX’s own internal payloads rather than commercial customers.
AST SpaceMobile’s dependence on third-party launch providers leaves its BlueBird satellite rollout exposed to scheduling delays and capacity constraints as the Falcon 9 commercial market contracts.
SpaceX launched BlueBirds 8 through 10 in June and BlueBirds 11 through 13 earlier this month, bringing AST SpaceMobile to 12 commercial BlueBirds in orbit as of August 10.
The company has 10 launches booked across two providers and is targeting deployment of approximately 45 satellites by early 2027 to support initial commercial service.
Freeing Florida pad time from Starlink missions could benefit AST SpaceMobile’s booked Falcon 9 flights by improving scheduling capacity at the Cape Canaveral complex.
Intuitive Machines faces comparatively less exposure to the Falcon 9 transition since its lunar missions are predominantly backed by NASA contracts rather than commercial arrangements.
Its IM-3 mission, carrying the Trinity Nova-C lander and Altus-1 lunar relay satellite, is targeting the second half of 2026 or a window extending into the first quarter of 2027, with IM-4 planned for 2027 also aboard Falcon 9.
Retail sentiment on Stocktwits remained cautious, with SPCX, ASTS, RKLB, and FLY all rated “bearish” and LUNR drawing a “neutral” reading, with message volume “low” across all five tickers.
Over the past year, LUNR has posted an 87% gain to lead the group, with RKLB up 42% and ASTS up 24%, while SPCX declined 14% and FLY fell 50%.
