What happened
SpaceX's Starship rocket completed its first successful orbital flight on September 29, 2026. CEO Elon Musk confirmed the milestone, posting that "First Orbital Flight Successful" according to 24/7 Wall Street. The Flight 14 mission achieved orbit despite one engine shutting down during ascent, according to Proactive Investors.
The achievement drew coverage from multiple financial outlets including Market Watch, The Motley Fool, Barrons, and Finbold. Market Watch highlighted Citi Research's note that Starship brings SpaceX "a step closer" to CEO Elon Musk's projection of reaching a $12 trillion valuation. Barrons reported bullish analyst ratings following reviews of the Starship program.
Why the stock moved
The orbital milestone represents a significant technical validation for SpaceX's largest and most ambitious vehicle. Starship is central to the company's long-term plans for lunar missions, Mars colonization, and heavy satellite deployment. Multiple analysts cited in Finbold and Barrons updated their SpaceX price targets following the Flight 14 achievement.
The news followed several days of positive coverage around Starship development. On September 28, The Motley Fool published an analysis titled "SpaceX's Starship Just Reached Orbit For The First Time. Is it Lift-Off Time For the Stock?" The site also examined whether Starship, Starlink, or xAI could move SPCX stock most in 2027.
GuruFocus and Invezz reported that analysts are viewing SpaceX's potential compute-leasing business as an emerging revenue driver alongside the core launch business.
The numbers
SPCX closed at $149.27 on September 29, up 2.6% for the regular session. Post-market activity showed a modest additional gain of 0.19% to $149.56. Trading volume totaled approximately 80 million shares, roughly in line with the stock's average daily volume of 80.3 million shares. The company's market capitalization stands at approximately $1.12 trillion with 7.49 billion shares outstanding.
Short interest sits at 162.3 million shares with 2.02 days to cover, suggesting modest bearish positioning ahead of the announcement.
The company's most recent SEC filings include an 8-K filed August 14, 2026, and a 10-Q filed August 4, 2026.
What to watch
Investors will monitor for details on when Starship's orbital capability translates to commercial missions. The vehicle's reusability and payload capacity could eventually support Starlink expansion and government contracts under the Starshield program. Barrons noted analyst enthusiasm around the vehicle's development trajectory following the Flight 14 success.
SpaceX's next operational milestones for Starship, including payload deployment or reusability demonstrations, may drive further analyst adjustments. The company's quarterly filings and any updates to Starlink subscriber growth or contract awards will provide additional data points for the investment case.
