Elon Musk has done something nobody in corporate history has ever pulled off. He took two private companies, merged them at a combined valuation of $1.25 trillion, and is now gearing up for an IPO that would value the result at $1.75 trillion. That is not a typo. That would be the largest initial public offering ever, by a factor that makes Saudi Aramco look modest.

SpaceX officially absorbed xAI in February 2026 in what analysts are calling the largest private corporate combination in history. The logic is straightforward if you squint: rockets need AI for autonomous navigation, satellite networks generate data that AI can process, and Grok needs compute infrastructure that SpaceX can help finance. The reality is messier. This is Musk consolidating his empire into a single entity that touches space, telecommunications, artificial intelligence, and semiconductor fabrication.

The IPO That Could Break Wall Street

SpaceX has confidentially filed for an IPO that is expected to value the merged company at $1.75 trillion. For perspective, Apple took 44 years to reach that market cap. Musk wants to get there on day one of trading.

The timing is deliberate. The secondary market for AI company shares has never been hotter. According to TechCrunch, Rainmaker Securities president Glen Anderson says private share trading is at historic highs, with AI companies driving most of the volume. Musk wants to ride that wave before it crests.

What This Means for the AI Race

The merger changes the competitive landscape in ways that should worry OpenAI and Anthropic. SpaceX-xAI will have access to a massive compute footprint, vertically integrated hardware supply chains, and the ability to fund AI research with aerospace cash flow. Grok may be the weakest of the frontier models today, but being backed by the most valuable private entity in human history tends to close capability gaps quickly.

Meanwhile, the secondary market is delivering its own verdict. Bloomberg reports $2 billion in institutional capital chasing Anthropic shares with almost no sellers, while roughly $600 million in OpenAI shares sit unsold. Investors are repricing the AI race in real time, and the SpaceX IPO could redirect massive amounts of capital that might otherwise flow to AI-pure-play companies.

The question nobody can answer yet: is a rocket company that also does AI worth $1.75 trillion, or is this the moment where Musk conglomerate finally tries to do too many things at once? History says conglomerates get punished by markets. But Musk has made history look wrong before.
