SpaceX's $75bn IPO breaks from Wall Street tradition on two counts

SpaceX is days away from what would be the largest initial public offering in history, and, predictably for an Elon Musk company, it is doing things differently.

Rather than following the conventional playbook, where companies announce a price range, spend weeks on investor roadshows, and set a final price based on demand, SpaceX has opted for the highly unusual approach of setting a fixed price of $135 per share ahead of presentations to investors and formal bookbuilding.

The company is targeting a raise of $75 billion, selling 555.6 million shares, at a valuation of at least $1.8 trillion.

There is no rule banning the approach, but it is a significant departure from standard practice.

In a conventional IPO, a price range serves two purposes: it frames valuation expectations and gives underwriters room to adjust to demand signals. By locking in a price upfront, SpaceX is, in effect, telling the market it does not need that mechanism. It already knows what it is worth.

That confidence may be warranted given the company's profile, but the timing is genuinely complex. Alphabet has announced an $80 billion equity raise for AI infrastructure, directly competing with SpaceX for institutional capital at precisely the same moment.

Behind them, OpenAI and Anthropic are both preparing listings of their own, offerings that will test whether investor appetite for transformative but loss-making AI ventures has a ceiling.

SpaceX's own prospectus disclosed AI-related losses of more than $6 billion in 2025, with a further $2.5 billion burned in the first quarter of 2026 alone. The company posted a net loss of $4.28 billion in that quarter against a $1.75 trillion target valuation. That is not the profile of a business priced for caution.

In another break from convention, SpaceX has reserved 30% of its IPO shares for retail investors, three times the historical norm for major listings. The roadshow began on 4 June, with pricing expected on 11 June and trading set to begin on 12 June under the Nasdaq ticker SPCX.

The deal would more than double Saudi Aramco's 2019 listing as the largest IPO on record. Whether the fixed-price structure reflects supreme self-assurance or a deliberate squeeze on Wall Street's standard bookbuilding leverage is an open question.

Either way, the next week will tell markets something important: not just about SpaceX, but about how much further the AI capital cycle has to run.
