SpaceX shares fell further in premarket trading July 17 after a Starship test flight was aborted when several engines failed to start, according to CNBC and Ars Technica reporting -- a fresh, technical operational setback layered directly on top of the stock's already-below-issue-price slide from earlier in the week.
This is a meaningfully different data point than the stock-price and Musk-net-worth story that dominated headlines just a day earlier: rather than a market-sentiment or political overhang, it's the underlying vehicle-testing program itself hitting a visible, engineering-level snag in full public view, on a test flight that had presumably been scheduled and anticipated by investors and space-industry watchers alike.
“What to watch next: SpaceX's timeline for the next Starship test attempt, and whether the stock stabilizes or continues sliding further below its $135 issue price.”
Starship's reusability roadmap and launch cadence sit at the center of the bull case embedded in SpaceX's roughly $1.7 trillion IPO valuation -- the vehicle is meant to eventually handle both Starlink satellite deployment at massive scale and NASA's Artemis lunar-lander contract, meaning any visible technical setback speaks directly to execution risk on the exact programs the valuation assumes will succeed on schedule.
For the late-stage VC funds and SPVs still holding pre-IPO SpaceX positions at marks well above the current $135 issue price, a second consecutive negative data point compounds the pressure building since the stock first traded below issue price -- turning what looked like it might be a brief, sentiment-driven dip into a more sustained pattern that public shareholders and private markholders alike now have to take seriously.
The bear case: scrubbed test flights due to engine issues are a normal, expected part of any aggressive rocket-development program, and SpaceX has successfully worked through numerous prior Starship setbacks on its way to eventual successful flights; a single aborted test doesn't necessarily indicate a deeper problem.
