SpaceX locked in its IPO valuation at $135 per share, pricing more than 555 million shares in what becomes the world's largest public offering. The company will debut Friday on a major exchange, giving Elon Musk's aerospace venture its first path to public capital markets.

The $135 price point values SpaceX at approximately $75 billion based on fully diluted shares. This marks a decisive moment for the commercial space sector, which has drawn institutional and retail investor appetite as government contracts and satellite internet demand accelerate globally.

SpaceX raised its target price range twice during the roadshow, signaling strong demand from institutional investors. The final pricing landed at the top of the marketed range, suggesting the market views the company's government contracts, Starlink satellite internet expansion, and Mars ambitions as worth a premium valuation relative to aerospace peers.

The offering itself generates roughly $75 billion in gross proceeds, making it substantially larger than the 2014 Alibaba IPO that previously held the record for largest global offering by capital raised. The scale reflects both SpaceX's business scale and investor enthusiasm for space economy exposure.

SpaceX operates two primary revenue streams. Government contracts with NASA and the U.S. Space Force drive predictable revenue from national security launches and cargo resupply missions. Starlink, the satellite internet constellation, has already secured millions of subscribers globally and represents a long-term growth engine competing against traditional broadband providers.

The IPO timing comes as defense spending remains elevated and space becomes a contested domain between superpowers. SpaceX holds dominant market share in U.S. commercial launch capability. Friday's debut will immediately test whether that operational dominance translates to sustained stock performance or whether valuation expectations prove stretched.

The offering also allows some early SpaceX investors and employees to liquidate positions, though Musk retains significant control through voting structures typical of growth-stage tech companies transitioning public.

Investors monitoring aerospace valuations and government spending trends should watch the opening day volume and institutional accumulation patterns closely.
