SpaceX’s blockbuster market debut is set to begin Friday after the company priced its IPO at $135 a share, generating approximately $75 billion in gross proceeds. The deal consists entirely of newly issued stock, with over 555 million Class A shares sold and an option for underwriters to acquire another 83.3 million shares.

The company will trade on Nasdaq and Nasdaq Texas under the ticker SPCX. The offering is among the largest IPOs ever completed and represents a major milestone for Elon Musk’s space company as it opens ownership to public investors.

Orders from retail investors to buy SpaceX shares have exceeded $100 billion ahead of Friday’s IPO, according to a Bloomberg report citing people familiar with the matter.

Separately, the Wall Street Journal reported that BlackRock sought to purchase at least $5 billion of shares in the offering. Retail investors have requested more than $70 billion in stock amid strong appetite for the long-awaited public debut.
