SpaceX IPO: 5 Stocks to Buy Before the Sector Soars

Bloomberg reported that Elon Musk's SpaceX is preparing to file for an IPO, targeting roughly $75 billion in proceeds, which would make it the largest initial public offering in history. The combined entity, which now includes Musk's xAI venture, is expected to seek a valuation between $1.5 trillion and $1.75 trillion, with a listing likely in June.

The market's reaction was immediate and powerful. Publicly traded space stocks surged on the news, with Rocket Lab (RKLB) up 10%, AST SpaceMobile (ASTS) jumping 12%, and Firefly Aerospace (FLY) rocketing 16%. The message was clear: the arrival of the industry's dominant player to the public markets is seen as a major validation event for the entire sector.

SpaceX in 2026 is a different beast than many imagine. Its Starlink satellite internet division now has over 9.2 million subscribers and generated more than $16 billion in revenue last year, with software-like margins. The launch business remains dominant, controlling roughly 80% of global commercial launch mass, with the massive Starship rocket now operational.

The confidential SEC filing allows SpaceX to work through regulatory details privately before a public roadshow. If timelines hold, institutional investors could be pricing their allocations by April, setting the stage for a historic market debut.

This IPO fundamentally changes the investment landscape for the space economy. It will bring unprecedented mainstream investor attention and capital into a sector that was once considered niche. The sheer size of the offering will force every major fund to consider space exposure, and that spotlight will shine on the existing public companies.

For investors, the core opportunity and challenge is that you cannot buy SpaceX stock today. Therefore, positioning in the publicly traded companies that are poised to benefit from the incoming capital and sector re-rating becomes the primary play. These stocks act as proxies for the SpaceX momentum.

However, the risks are substantial. Many of these stocks trade on sky-high momentum multiples, not fundamentals. Rocket Lab (RKLB) trades at 59 times trailing revenue, while AST SpaceMobile (ASTS) trades at over 500 times. If SpaceX's IPO disappoints or faces delays, the entire sector could see a sharp correction.

Furthermore, SpaceX itself is the dominant competitor in launch and satellite communications. Its public listing will give it even more capital to press its advantages, directly threatening the addressable markets of companies like ASTS, RKLB, and FLY. Profitability also remains elusive for most pure-play space companies, making them dependent on continued access to capital markets.

Despite the risks, the structural tailwinds are powerful. Government space spending is accelerating, commercial satellite demand is surging, and the space economy is now a $600 billion industry growing at 9% annually. The SpaceX IPO is the catalyst that could supercharge this growth for years to come.
