TLDR
- SpaceX shares fell below IPO price despite a successful Starship Flight 13 heat-shield test.
- Investors want evidence of rapid refurbishment, lower costs, and repeatable reusability.
- Starship completed key in-space maneuvers and returned intact after a high-stress reentry.
- Upcoming earnings and Flight 14 could become major catalysts for SpaceX stock.
SpaceX shares slipped below their initial public offering price on Monday, signaling growing investor skepticism even as the company achieved one of its most encouraging Starship engineering milestones to date.
The stock closed at $113.50, down 1.36% for the session, and continued lower in after-hours trading to around $112.03.
The decline leaves SpaceX nearly 16% below its June IPO price of $135 and almost 50% beneath its post-listing peak of $225.64. While the company remains one of the world’s most valuable aerospace and technology businesses, the market is increasingly demanding evidence that Starship can become not just reusable in theory, but economically reusable in practice.

Heat Shield Under Pressure
Flight 13 was designed to push Starship harder than previous missions. SpaceX intentionally exposed the vehicle’s heat-shield tile system to greater acceleration and dynamic pressure during reentry, creating a more demanding test of tile attachment and structural performance.
The spacecraft later splashed down intact in the Indian Ocean, and six of the 20 deployed Starlink V3 satellites photographed the heat shield during flight. Elon Musk described the mission as successful and said the company collected more data than expected.
From an engineering perspective, the outcome was significant. The upper stage also completed several planned objectives, including deploying 20 Starlink satellites, reigniting a Raptor engine in space, performing a banking maneuver, executing a landing flip, and carrying out a controlled descent burn before splashdown.
These achievements suggest that SpaceX is making meaningful progress toward a reusable upper stage, long considered the most difficult part of the Starship architecture.
Reuse Economics Still Missing
The market’s muted response highlights a different concern. Investors are no longer asking whether Starship can survive reentry; they are asking whether it can be inspected, refurbished, and launched again quickly enough to transform SpaceX’s cost structure.
The company did not disclose how many heat-shield tiles required replacement, how long refurbishment would take, or what the expected per-flight cost might be after reuse. Without those numbers, analysts cannot estimate future margins or determine when Starship could begin generating substantial operational leverage.
The distinction is crucial. A spacecraft that returns intact is an engineering achievement. A spacecraft that returns, undergoes minimal maintenance, and flies again within days or weeks is a fundamentally different business model.
That is the proof Wall Street is still waiting for.
Booster Questions Persist
Not everything went perfectly during Flight 13. The Super Heavy booster completed its ascent and boostback phases, but not all landing engines successfully reignited before splashdown. The booster therefore descended faster than intended, continuing a pattern that has appeared in earlier tests.
This matters because full-stack reusability requires reliable recovery of both the upper stage and the booster. Progress on one half of the system does not yet establish a fully reusable launch vehicle.
SpaceX has indicated that the next major milestone could be an attempted upper-stage tower catch on Flight 14, assuming post-flight reviews do not uncover significant issues. The company has not announced a launch date.
Earnings Become Next Catalyst
The stock reaction also reflected a comparison with peers. Rocket Lab shares moved higher after the company secured a $266 million U.S. Space Force contract, giving investors a clearer line of sight to future revenue. SpaceX, by contrast, delivered an engineering milestone without providing equivalent commercial visibility.
Morgan Stanley maintained an Overweight rating and a $300 price target, arguing that the successful satellite deployment, engine relight, and intact splashdown were important steps forward. However, even bullish analysts acknowledge that rapid turnaround and repeatable reuse remain the critical missing pieces.
Attention is now turning to SpaceX’s expected second-quarter results on August 4. Analysts are projecting roughly $6.82 billion in revenue and a loss of about $0.23 per share. Investors will be looking for commentary on Starship spending, Starlink V3 deployment timing, refurbishment targets, and long-term launch economics.
The broader implications extend beyond SpaceX shareholders. NASA’s Artemis schedule still depends on several capabilities that Starship has not yet demonstrated, including orbital operations, docking, and propellant transfer.
Flight 13 may have changed the conversation around heat-shield survival. The next phase is about repeatability. Until SpaceX can show that Starship can return, be quickly cleared for flight, and launch again at materially lower cost, the market appears unwilling to reward engineering progress with a higher valuation.
