SpaceX IPO Prospectus Filing Expected as Soon as Next Week

CNBC reported Thursday that SpaceX is preparing to publicly file its IPO prospectus as soon as next week. The move brings Elon Musk’s reusable rocket company closer to what analysts expect to be the largest public market debut in history.

Roadshow and Timeline Take Shape

Sources told CNBC the company is targeting a June 8 roadshow launch to formally pitch the offering to institutional investors. Securities rules require the prospectus to be publicly disclosed at least 15 calendar days before that roadshow begins. SpaceX and its advisers are reportedly aiming to file slightly ahead of that minimum window. That would give prospective investors additional time to review the company’s financial disclosures before marketing begins. Sources cautioned the schedule remains subject to change. SpaceX did not respond to CNBC’s request for comment.

A Valuation Shaped by the xAI Merger

SpaceX confidentially filed IPO paperwork in April, CNBC noted. The company’s expected scale is rooted in its February merger with xAI, Musk’s artificial intelligence venture. That combination was valued at $1.25 trillion at close. Bloomberg separately reported that SpaceX is targeting a listing size of roughly $70 billion to $75 billion. That would place the deal at more than double the size of Saudi Aramco’s 2019 offering, which currently holds the record for the world’s largest IPO.

Advisers Scout Global Retail Channels

Because no company has ever attempted to sell this volume of shares in a single offering, SpaceX’s bankers are pursuing unconventional distribution strategies. Advisers are actively courting brokers in the United Kingdom, Japan and Canada to secure allocations for long-term retail clients outside the United States. The outreach reflects a deliberate effort to broaden the investor base beyond traditional U.S. institutional buyers.

Market Appetite Arrives at the Right Moment

Wall Street’s enthusiasm for the deal is landing against a backdrop of renewed IPO hunger. AI chipmaker Cerebras surged 68% on its market debut Thursday, closing with a market capitalisation near $95 billion. That performance signals strong investor appetite for AI-adjacent listings. OpenAI and Anthropic are also reportedly pursuing offerings before year-end, with both companies chasing valuations above $1 trillion. The cluster of mega-cap AI listings could define the second half of 2026 for equity markets.
