NEW YORK, July 17, 2026 – SpaceX (NASDAQ:SPCX) shares tumbled 4.52% to $125.18 in early premarket trading on Friday, following the abrupt cancellation of Starship Flight 13 on Thursday evening. The failed launch wiped out an estimated $53 billion in implied equity value, according to preliminary calculations.
Launch Abort Details
Flight 13 was scrubbed just before liftoff when four of the 33 Super Heavy booster engines failed to ignite. The automated launch abort system then shut down the remaining 29 engines, keeping the rocket safely on the pad. Elon Musk confirmed via Reuters that two Raptor engines would be replaced, with a retry likely early next week.
The suborbital mission was designed as a systems test, carrying 20 V3 satellites that would briefly link with the existing Starlink network before burning up on reentry. SpaceX noted the flight would have added no lasting network capacity.
Market Reaction
The $53 billion loss is a preliminary estimate based on a 3.08% aftermarket decline applied to SpaceX's $1.73 trillion closing market value. The stock had already closed at $131.11 on Thursday, below its $135 IPO price for the first time, marking its fifth consecutive decline.
The broader space sector was also under pressure. Rocket Lab (NASDAQ:RKLB) fell 11.61%, while AST SpaceMobile (NASDAQ:ASTS) dropped 17.04%. The Nasdaq Composite lost 1.47%. The additional decline in SpaceX shares began after the abort, suggesting investors isolated launch risk from the broader selloff.
Implications for Starlink Deployment
The abort raises concerns about the timeline for deploying next-generation V3 satellites. An operational Starship can carry up to 60 V3 satellites, with a total designed downlink capacity of 60 Tbps. In comparison, Flight 13's 20 satellites would have provided only 20 Tbps. SpaceX expects Starship payload delivery to begin in the second half of 2026, but its prospectus warns that delays could slow deployment.
For context, SpaceX spent $3.004 billion on space-segment R&D in 2025. The estimated $53 billion loss is nearly 18 times that annual spending, highlighting the market's sensitivity to launch milestones.
What's Next
Next week begins with engine replacement and a new launch window. Investors will be watching closely to see if all 33 Raptors ignite and remain stable. President Gwynne Shotwell has indicated that Flight 14 could attempt orbit, depending on Flight 13's success. SpaceX targets a monthly launch cadence.
Risks remain, including lower liquidity and higher volatility in extended-hours trading. Further engine or pad issues could delay the V3 rollout and its capacity gains. The market will be watching for any updates from SpaceX as the next launch attempt approaches.
