SpaceX stock came under pressure after Elon Musk laid out a path toward eventually retiring the company’s Falcon rocket family and shifting engineering and manufacturing resources toward Starship.
Shares of Space Exploration Technologies (NASDAQ: SPCX) closed Monday at $135, down roughly 1.4%. The stock was attempting a modest recovery in Tuesday premarket trading.

The catalyst was Musk’s clearest indication yet that Falcon 9 and Falcon Heavy could eventually be phased out.
“Once Starship is flying reliably several times per week, it makes sense to shift super scarce SpaceX engineering and production resources to Starship to get launch rate to several times per day, which means winding down Falcon,” Musk said on X.
Falcon 9 Retirement Raises the Stakes for Starship
Importantly, Musk’s comments describe a condition rather than a fixed retirement date. Falcon is still the backbone of SpaceX’s launch business and is operating at an extraordinary pace.
SpaceX completed its 100th Falcon-family mission of 2026 on Aug. 22, including 99 Falcon 9 flights, after Falcon 9 set a record with 165 successful missions in 2025. Another mission was scheduled to see booster B1067 fly for a record 37th time.
The transition therefore carries massive execution risk. Starship is designed to reuse both its booster and upper stage, which could potentially lower launch costs dramatically while supporting far higher launch frequencies.
However, SpaceX still has major milestones to clear. Musk recently pushed the first attempt to catch Starship’s upper stage with its launch tower back by several months. He expects the first reflight of a Starship upper stage around the end of 2026 or early 2027, while Flight 14 is expected to attempt Starship’s first orbital mission.
SpaceX Stock Faces Another Near-Term Test
Rocket development is not the only source of volatility for SPCX investors. Up to 319 million shares held by early investors and employees are becoming eligible for trading, equivalent to roughly 7% of insider-owned stock. The additional supply could increase short-term volatility even if insiders choose not to sell.
Institutional investors are hardly universally bearish, however. Cathie Wood’s ARK Invest bought more than 200,000 SpaceX shares worth nearly $27 million on Friday.
That leaves investors weighing one of SpaceX’s biggest strategic bets yet: replacing perhaps the world’s most successful operational rocket with a system that promises vastly better economics — but still has plenty left to prove.
