#SpaceXSecretlyFilesForIPO

The biggest open secret in tech just became official. SpaceX quietly filed a confidential S-1 with the SEC on April 1, 2026, setting the stage for what could be the largest IPO in history.

The numbers alone are staggering. The company is targeting a valuation north of $1.75 trillion and aims to raise as much as $75 billion in the offering, which would shatter Saudi Aramco's $29 billion record debut from 2019 by a wide margin. A June listing is reportedly on the table.

This is not just a rocket company going public anymore. Earlier this year, SpaceX absorbed Musk's AI venture xAI in an all-stock deal, folding together Starlink's satellite broadband empire, Falcon 9's launch dominance, and xAI's artificial intelligence infrastructure into one single entity. Last year the combined business reportedly pulled in roughly $16 billion in revenue with about $8 billion in profit. The IPO is designed to fund both the capital-hungry AI buildout and the next generation of space infrastructure, including solar-powered orbital data centers that Musk believes will be the cheapest path to meeting global AI compute demands within a few years.

When the listing eventually happens, Musk will become the first person in history to simultaneously lead two separate trillion-dollar publicly traded companies. He currently owns roughly 42% of SpaceX according to available data, a stake whose value will shift once new shares are issued.

The confidential filing gives SpaceX room to negotiate with regulators before releasing public numbers, with full disclosure required at least 15 days before the road show kicks off.

OpenAI and Anthropic are also quietly moving toward their own public offerings this year, making 2026 shaping up to be one of the most consequential years for tech capital markets in a generation. But SpaceX, sitting at the intersection of space, AI, and internet infrastructure, is in a category of its own.
