SpaceX completed the largest stock-market debut in history on June 12, 2026, raising $75 billion [1] during its initial public offering.
The debut marks a pivotal shift in the aerospace and AI sectors, as the capital influx supports the company's growth following its merger with xAI [2, 3]. The scale of the offering reflects the immense investor appetite for integrated space and artificial intelligence infrastructure.
Trading on the Nasdaq exchange in the U.S. began with shares opening at $150 [4]. The stock experienced a significant first-day surge, with reports placing the increase between 17% and 20% [4]. This momentum pushed the company's market capitalization to approximately $2.2 trillion [1]. Other reports confirmed the valuation exceeded $2 trillion [5].
The financial windfall has established founder Elon Musk as the world's first trillionaire [1, 2]. This milestone follows a broader trend of mega-IPOs from AI-related companies seeking massive capital to scale operations [2, 3].
By transitioning from a private entity to a public company, SpaceX has gained access to a vast pool of liquid capital. This funding is intended to accelerate the company's ambitious goals in satellite deployment, and interplanetary travel. The merger with xAI further positions the company at the intersection of autonomous intelligence and orbital logistics.

The SpaceX IPO represents more than a personal financial milestone for Elon Musk; it signals the market's belief in the convergence of AI and aerospace. By merging with xAI and going public, SpaceX is transitioning from a launch provider into a massive data and infrastructure conglomerate. This valuation sets a new benchmark for private-to-public transitions in the tech sector and provides the company with the financial leverage to dominate the next era of orbital economy.
