SpaceX IPO Could Hit $85.7B If Overallotment Option Exercised

📌 UPDATE — June 4, 2026

New reports indicate SpaceX is targeting a staggering $1.75 trillion IPO valuation — a figure that puts the company's growth trajectory in breathtaking perspective. SpaceX was valued at under $100 million when Elon Musk founded it in 2003, meaning the company has grown its valuation by more than 17,000x in roughly two decades. This $1.75T target would dwarf the $85.7B offering figure previously reported and would place SpaceX among the most valuable companies ever to go public. The reported valuation reflects SpaceX's dominance in commercial launch, Starlink's expanding subscriber base, and its long-term ambitions in deep space exploration.

📌 UPDATE — June 4, 2026

SpaceX has officially confirmed retail investors will be able to participate in the IPO at the same price as institutional investors, with an expected share price of $135 per share under the ticker symbol SPCX. The company publicly thanked @TuttleCapital for reserving the SPCX ticker, adding a lighthearted "live long and prosper 🖖" to the announcement. SpaceX also reinforced its broader strategic pitch, describing itself as "the only company building the infrastructure of the future across space, connectivity, and AI."

The SpaceX IPO is now moving into its final stretch, with SoFi confirming the offering is currently on track for a June 12th debut (dates subject to change). Retail investors can now submit their indication of interest for SpaceX shares directly through SoFi, which is one of a handful of brokerages named in SpaceX's S-1 filing designated to allocate IPO shares to everyday investors — a notable step toward broader public access to the offering.

SpaceX's historic IPO just got a potential upside figure attached to it. If demand is strong enough for underwriters to fully exercise their overallotment option, the total value of shares sold could climb by approximately $11.25 billion — pushing the offering's total size to roughly $85.7 billion, according to analyst and Tesla tracker Sawyer Merritt.

The overallotment option — sometimes called a greenshoe — is a standard IPO mechanism that lets underwriters sell additional shares beyond the original offering size when investor demand exceeds expectations. It's a signal of confidence, not a guarantee: the option only gets exercised if the book is genuinely oversubscribed.

The base offering itself is already staggering. According to SEC filings, SpaceX set its IPO price at $135 per share across 555.56 million shares, targeting $75 billion in proceeds. That alone would make it the largest IPO in history. The company is aiming for a Nasdaq listing under the ticker SPCX as early as June 12, 2026, with Goldman Sachs and Morgan Stanley leading underwriting duties. The implied valuation sits in the $1.75 trillion to $2 trillion range — a figure that dwarfs most publicly traded companies on earth.

The $85.7 billion ceiling, if reached, would represent a landmark moment not just for SpaceX but for the broader private-to-public transition in the aerospace and technology sectors. Whether underwriters pull the trigger on the full overallotment will depend on order book strength in the days leading up to the June 12 target date. Watch the S-1/A filings — SpaceX already submitted an amended registration on June 3, suggesting active fine-tuning ahead of launch.
