SpaceX: IPO Valuation Note

This month's SUINS note steps away from the macro tape to confront the deal everyone is talking about. On 12 June, SpaceX is set to become the largest IPO ever at an implied equity value near $1.75 trillion. We asked a deliberately simple question: ignore the headline price, value the three businesses on their own cash flows, and see what the math actually supports.

Key Data Points:

The Ask: SpaceX is seeking roughly $75bn (about 3x Saudi Aramco's record 2019 raise) at ~$1.75tn implied equity, or $135 per share, listing on the Nasdaq as SPCX.

Our Base Case: A 20-year sum-of-the-parts DCF, already crediting two decades of aggressive outperformance, lands at ~$417bn of equity value (~$32 per share), roughly one-quarter of the ask and a ~4.2x gap. Even our most generous scenario reaches only ~$593bn.

Starlink Is the Anchor: At ~$226bn, satellite broadband is over half of our valuation and the only consistently profitable, cash-generative unit, behaving like a high-growth emerging-markets telecom.

AI and Space Are Optionality, Not Foundation: xAI (~$107bn) and the launch business (~$101bn) are earlier, thinner and far more uncertain, with implied-value ranges wide enough that reasonable people can disagree by hundreds of billions.

A Tiny Float, Total Control: Only ~3 to 4% of the company is offered, while super-voting stock leaves Elon Musk with over 82% of the vote, so small flows can swing the implied cap sharply.

The Bottom Line:

On the economics SpaceX itself discloses, the company is worth a fraction of its IPO price. This is not a verdict on an extraordinary operating business, it is a verdict on the price: the gap between intrinsic value and the offer is a bet on narrative, optionality and momentum, not on the cash flows in the filing. With index-inclusion mechanics and a minuscule float, the stock can still run well past fundamentals, which is exactly why valuation discipline matters most here.
