SpaceX is gearing up for what could become the largest initial public offering in history, with shares expected to begin trading on the Nasdaq next week. The rocket manufacturer plans to sell 555,555,555 shares at $135 each, generating approximately $75 billion in proceeds. This massive offering positions the company to join the ranks of the world's most valuable businesses.

The IPO targets a valuation of roughly $1.77 trillion, representing a doubling from SpaceX's worth just six months prior. Such rapid appreciation reflects investor enthusiasm for the company's dominant position in commercial spaceflight and its Starlink satellite internet constellation. The valuation would place SpaceX alongside tech giants like Apple and Microsoft in terms of market capitalization.

Investor appetite for the offering will largely hinge on confidence in Elon Musk's ambitious long-term vision, including Mars colonization and space-based data centers. These futuristic projects carry significant execution risk but also potential for massive returns if realized. The company's track record of vertical integration and reusable rocket technology provides some foundation for these goals.

The Wall Street Journal is hosting a live Q&A session on June 5 to discuss the IPO details and answer subscriber questions before the expected June 12 trading debut.
