SpaceX IPO News Triggers Rally in Aerospace Stocks: AST SpaceMobile (ASTS) and Rocket Lab Lead Gains

Key Takeaways

• Reports indicate SpaceX may file IPO paperwork imminently, seeking a $1.75 trillion market capitalization
• The potential offering could generate upwards of $75 billion, establishing a new record for public listings
• Aerospace equities rallied Wednesday, with Firefly Aerospace climbing 16% and AST SpaceMobile advancing 10%
• Rocket Lab and York Space posted substantial gains following the IPO speculation
• A successful public debut could elevate Elon Musk to trillionaire status

Elon Musk’s SpaceX may submit documentation for its public market debut in the coming days, based on reporting from The Information. Such a move would initiate what analysts expect could be the most significant stock offering ever recorded.

The aerospace manufacturer is reportedly seeking a market capitalization near $1.75 trillion. Should the equity sale generate the rumored $75 billion-plus, it would eclipse every previous IPO in financial history.

Speculation surrounding the imminent filing propelled space-focused equities significantly higher during Wednesday’s trading session. Firefly Aerospace topped the sector’s performance with a 16% advance.

AST SpaceMobile and Rocket Lab both registered approximately 10% increases. York Space, which completed its own public listing in January, climbed 5%.

AST SpaceMobile, Inc., ASTS

Intuitive Machines posted gains approaching 15%. Planet Labs surged more than 10%, while Sidus Space jumped nearly 19%.

Elon Musk established SpaceX in 2002. Beyond the aerospace company, Musk oversees Tesla, X, Neuralink, and xAI.

SpaceX completed the acquisition of Musk’s xAI last month. That transaction valued the merged entity at $1.25 trillion.

According to Forbes, Musk’s current net worth exceeds $820 billion. An IPO achieving the anticipated valuation could propel his personal wealth beyond the $1 trillion threshold.

Over the past twenty years, SpaceX has established itself as a dominant force in aerospace. The company maintains multibillion-dollar contractual relationships with the United States government.

Satellite Operations and Defense Contracts

SpaceX manages Starlink, a global satellite internet network currently consisting of more than 9,500 orbiting satellites. In January, Musk floated the concept of scaling this constellation to 1 million satellites, a proposal that has generated pushback from environmental researchers.

The broader space industry has received additional momentum from President Donald Trump’s proposed “Golden Dome” missile defense architecture. Enterprises specializing in defense technologies and satellite communications have experienced heightened investor attention in response.

Orbital Data Infrastructure

Industry observers are increasingly examining the feasibility of deploying data processing facilities in orbit to address escalating terrestrial electricity expenses. The aggressive expansion of artificial intelligence computing infrastructure has intensified power consumption, positioning space-based solutions as a potential alternative.

Nevertheless, this concept confronts significant obstacles, particularly regarding launch economics and spacecraft capacity constraints.

SpaceX has not issued official confirmation regarding the IPO submission. The BBC indicated it reached out to SpaceX for verification but had not received a response as of publication.

Firefly Aerospace, which transitioned to public markets in August 2025, appreciated 16% Wednesday. York Space, which debuted in January 2026, advanced 5%.
