SpaceX is considering a mid-June 2026 initial public offering that could raise as much as $50bn and value the company at roughly $1.5tn, in what would be the largest stock market debut in history.

The potential listing, first reported by the Financial Times, would eclipse Saudi Aramco’s $29bn IPO in 2019, which valued the oil giant at $1.7tn.

Chief financial officer Bret Johnsen has held talks with existing private investors since December to explore the feasibility of a listing, the newspaper said. While founder Elon Musk has historically favoured keeping SpaceX private, the company’s surging valuation and the rapid growth of its Starlink satellite internet unit are understood to have shifted internal thinking.

Reuters reported last week that SpaceX is lining up four Wall Street banks to lead the transaction. A successful offering would mark a landmark liquidity event for the company’s private backers and employees.

The move comes as US equity capital markets rebound after several subdued years, with investors bracing for a wave of large-scale listings. Artificial intelligence groups including Anthropic and OpenAI are also laying early groundwork for potential IPOs.

For private equity and growth investors, SpaceX’s deliberations underscore renewed confidence in public markets as an exit route for scaled technology and infrastructure-heavy platforms.
