Musk Net Worth Falls Below $800 Billion After Starship Scrub

Elon Musk’s net worth fell below $800 billion after SpaceX aborted a Starship launch attempt, according to Forbes.

The latest estimate marks a drop from earlier valuations and follows a setback tied to SpaceX’s next-generation rocket program. The aborted launch drew attention to Starship’s role in the company’s plans and the stakes attached to major test milestones.

Forbes reported the decline in Musk’s net worth alongside separate coverage noting that Musk is no longer a “trillionaire,” citing changes in SpaceX’s stock price after the aborted launch. AOL.com also reported on the shift, referencing Forbes’ assessment and linking the move to SpaceX’s valuation changes following the scrubbed attempt.

SpaceX’s Starship is the company’s most prominent development program and is central to future heavy-lift missions. The vehicle’s testing cadence and outcomes have become closely watched moments for the company and for Musk, who leads multiple high-profile businesses.

Additional reports in recent days have pointed to technical issues during SpaceX rocket testing. The Arkansas Democrat-Gazette reported that SpaceX saw an engine failure at a rocket test. While the reports do not provide exhaustive technical detail, they underscore that propulsion performance remains a focal point in the testing and development of advanced launch systems.

The net worth move matters because Musk’s wealth is tightly linked to valuations of the companies most closely associated with him, particularly SpaceX. When a major program faces a public setback, investor and market perceptions can shift quickly, affecting private-company valuations used in wealth estimates compiled by outlets like Forbes.

The episode also highlights how closely watched Starship has become beyond aerospace circles. Starship testing has been treated as a marker for SpaceX’s broader ambitions, and high-visibility test days tend to have outsized reputational consequences compared with routine development work that happens out of public view.

What happens next will depend on SpaceX’s steps following the aborted attempt and the results of any follow-on testing. SpaceX typically proceeds through investigation, corrective actions, and another attempt once the company is ready, but no timeline is provided in the context available here.

For Musk, the immediate next chapter is whether SpaceX can move past the aborted launch and deliver a successful test milestone that stabilizes confidence around the program’s progress. The latest Forbes estimate places his fortune below $800 billion for now, reflecting how quickly headline events around Starship can ripple into widely followed measures of wealth.
