SpaceX shares jump 5% as Starship sets September 22 for first orbital flight

SpaceX shares climb on confirmed Starship launch date

SpaceX (NASDAQ: SPCX) shares rose sharply on September 16, 2026, trading at $151.12, up about 5% on the session, after Barron's reported that the company has set September 22 as the launch date for Starship's next test flight. The mission is positioned as the vehicle's first attempt to place its upper stage into a stable Earth orbit, a threshold that separates a rocket still in its test program from one capable of carrying revenue-generating payloads. The stock remained down roughly 7% from its June trading debut despite the day's gain.

Sector peers held flat, framing the move as SpaceX-specific

The broader space sector barely participated in the rally. The Procure Space ETF (NASDAQ: UFO) was up just 0.8% at $43.21, while the SPDR S&P 500 ETF Trust (NYSEARCA: SPY) rose 0.3% to $759.99. Rocket Lab (NASDAQ: RKLB) was essentially flat at $63.75, up only 0.3%, and AST SpaceMobile (NASDAQ: ASTS) traded at $59.27, up 0.85%. The narrow spread of peer moves signaled that investors were repricing SpaceX on its own headline rather than rotating into broad space exposure.

Why the orbital threshold matters commercially

Starship has flown twice since SpaceX began trading, and both previous attempts stayed suborbital, leaving September 22 as the first real test of whether the vehicle can complete an orbital mission. Reaching stable Earth orbit is the point at which Starship can begin hauling paying satellites rather than ferrying test articles. Wednesday's move tracked the launch date more than any long-range forecast, with near-term confidence dependent on the vehicle first completing an orbital run.

Cathie Wood's $10 trillion revenue projection

ARK Invest founder Cathie Wood separately projected that Starship could generate $10 trillion in annual revenue by the end of the decade, calling SpaceX's $1.75 trillion listing a bargain on that basis. Wood's projection builds from Starlink connectivity revenue per unit of launched network capacity rather than from launch fees, though the forecast rests on assumptions about flight cadence and payload utilization the vehicle has not yet demonstrated. The $10 trillion figure, if realized, would exceed the yearly economic output of every nation except the United States and China.

What's next on September 22

The September 22 attempt is the next real information point for SpaceX. A clean run to a stable orbit would open the door to revenue-carrying payload flights and begin validating the commercial timeline underpinning the company's current valuation, while a second suborbital outcome would keep that timeline open-ended and put renewed pressure on a stock still trading below its June debut levels.
