SpaceX IPO prospectus to be disclosed as early as next week; roadshow to begin on June 8

According to CNBC on May 14 citing multiple insiders, SpaceX plans to publicly file its prospectus as early as next week. The company secretly submitted its IPO application in April. Insiders confirmed that SpaceX targets launching the roadshow on June 8; under the rules, the relevant documents must be made public at least 15 natural days before the roadshow, and the exact timing may still be adjusted.

Confirmed IPO Process Timeline

Based on information provided to CNBC by insiders, insiders also confirmed the timeline may still be adjusted:

April 2026: SpaceX secretly files its IPO application

Prospectus disclosure: earliest next week (exact timing may still be adjusted)

Target roadshow start date: June 8, 2026

Statutory disclosure requirements: documents must be made public at least 15 natural days before the roadshow

Starship 12th test flight target date: May 19, 2026 (previously confirmed by SpaceX)

Financing size and market backdrop: $75 billion of historical significance

If the target financing amount of $70 billion to $75 billion is achieved, it would surpass the following existing records:

Saudi Aramco (2019): about $29.4 billion, the current largest IPO globally

If $75 billion is reached: more than double the scale of the Saudi Aramco record

Meanwhile, the AI-related IPO market is heating up: Cerebras (an AI chip manufacturer) listed on May 14, jumping 68% on its first day, closing with a market cap of about $95 billion. OpenAI and Anthropic also plan to list as early as this year. The combination of SpaceX and xAI gives this IPO a dual narrative covering both aerospace and AI.

Global retail allocation strategy: seeking non-US investors with longer holding periods

Given that the IPO size would be unprecedented, SpaceX’s advisors are exploring non-traditional distribution channels. Insiders said the advisors are reaching out to brokers in countries such as the UK, Japan, and Canada, seeking allocation shares for their clients, with the goal of attracting retail investors outside the United States who plan longer holding periods.

FAQ

Has the disclosure timing for SpaceX’s prospectus been finalized?

Based on CNBC’s report, insiders said the plan is to disclose as early as next week, but also clearly stated that “the exact timing may still be adjusted.” SpaceX has not issued an official response on this matter; all information comes from anonymous insiders and has not been formally confirmed by the company.

How does the merger of SpaceX and xAI affect this IPO?

In February 2026, SpaceX completed its merger with xAI, the artificial intelligence company of Musk. After the merger, the entity’s valuation reached $1.25 trillion. The merger integrates SpaceX’s aerospace business (including the Starlink satellite internet and the Starship rockets) with xAI’s AI technology, giving this IPO a dual positioning in both aerospace and artificial intelligence.

Why is the $75 billion financing target historically significant compared with Saudi Aramco?

Saudi Aramco’s IPO in 2019 raised about $29.4 billion, the largest IPO in the world to date. If SpaceX achieves its $70 billion to $75 billion target, it would surpass the Saudi Aramco record by more than two times, rewriting the global history record for IPO scale.
