- SpaceX stock trades near $144 as Elon Musk again leaves the door open to a possible Tesla-SpaceX merger
- Cathie Wood says Starship could generate about $1 billion per launch, implying $10 trillion annually at 10,000 flights
- Flight 14 is targeted for September 22, giving investors a nearer-term test for the SpaceX stock forecast
SpaceX stock is back in focus after Elon Musk again left the door open to a Tesla-SpaceX merger, just as Cathie Wood put a huge number on Starship’s long-term potential. Shares have slipped from last week’s highs, but the company’s next orbital Starship flight is only days away. Between the merger talk and Wood’s $10 trillion revenue math, investors suddenly have two very different reasons to watch what happens next.

SpaceX Stock Slips as Musk Reopens Merger Question

SpaceX closed Tuesday at $143.49, down 3.15% for the session and about 4.1% over five days. The stock is still above its $135 June IPO price, when SpaceX raised $75 billion at a $1.77 trillion valuation. It was called the largest US IPO on record.
More attention came as Musk revived the merger discussion at the All-In Summit. Asked why Tesla and SpaceX remain separate, he called it a “great question” and pointed to how closely the businesses are already working together. He stopped there. There was no deal, timeline, or structure announced. He added,
“With all this collaboration, on so many levels, who can imagine what action one might take when there’s so much close collaboration in so many areas.”
The financial links are already meaningful. Tesla’s latest SEC filing shows it recorded a $1.00 billion net gain on its SpaceX investment in the second quarter. Tesla’s operating income for the same period was just $398 million. That does not make a merger more likely, but it explains why the relationship is getting more attention from investors.
Cathie Wood Puts $10T Number on Starship Revenue
Cathie Wood’s SpaceX call is much more aggressive. She said a future Starship launch could generate around $1 billion in revenue. Apply that to Musk’s target of 10,000 annual flights by 2030, and the math reaches $10 trillion in yearly Starship revenue.
Wood’s $10 trillion figure is not a SpaceX forecast. It comes from applying Musk’s 10,000-flight target to her estimate that each Starship launch could bring in around $1 billion.
There is a nearer test coming first. SpaceX is targeting September 22 for Flight 14, which is expected to attempt Starship’s first orbital mission and deploy the first batch of Starlink V3 satellites. The launch remains subject to regulatory approval.
For the near-term SpaceX stock forecast, that flight gives investors something more concrete to watch. The merger is still speculation, while Flight 14 will show how much closer Starship is getting to regular commercial operations.
