Wall Street has rediscovered its appetite for the stars. Since SpaceX formally filed its IPO prospectus on 20 May 2026, offering the public its first detailed look at the company’s financials, listed space-sector stocks have moved higher. The filing has drawn fresh interest from both retail and institutional investors, increasing attention on a sector that had remained largely inaccessible through public markets.
The scale of what SpaceX is bringing to market is staggering. The company, which will list on the Nasdaq under the ticker SPCX, is seeking to raise upwards of $80 billion, which would handily eclipse the previous global IPO record of $29 billion set by Saudi Aramco in 2019. The deal is being underwritten by 23 financial institutions including Goldman Sachs, Morgan Stanley, Citigroup, and JP Morgan, and is targeting a valuation window of $1.75 trillion to $2 trillion, a range that would immediately place SpaceX among the most valuable publicly traded companies on Earth.
The SpaceX IPO buzz is also being backed by strong industry momentum. NASA is expanding its Moon Base plans, while US space spending is set to rise sharply, with the Space Force budget nearing $71 billion in 2027. Analysts say the global space economy could unlock trillions in value over the next two decades.
Companies like Rocket Lab and AST SpaceMobile have also gained investor attention on strong growth and ties with SpaceX. However, analysts remain cautious over SpaceX’s steep valuation and rising losses in its AI business, warning of short-term volatility after listing. For now, investor sentiment remains upbeat, with the IPO driving fresh interest across the space sector.
SpaceX IPO prospectus
SpaceX’s S-1 registration statement offers the first detailed public view of the company’s business operations ahead of its listing. The filing includes its Falcon launch business, Starship programme, Starlink satellite internet division and the artificial intelligence business linked to its merger with xAI. Analysts estimate Starlink could generate between $22 billion and $24 billion in revenue in 2026. In the filing, SpaceX estimates its total addressable market at $28.5 trillion across transport, communications, defence and orbital infrastructure.
Ahead of the listing, SpaceX also announced a 1-for-5 stock split, reducing the implied share price from about $526 to nearly $105. Reports indicate around 30% of the shares on offer may be allocated to retail investors.
As SpaceX remains privately held until its listing, investors have turned to publicly traded space companies linked to launches, satellites and defence contracts, driving a broad sector rally. Space-focused ETFs have also gained momentum this year, while Satellogic has emerged as one of the biggest movers with a sharp rise in its stock.
