SpaceX shares jumped almost 20% on Friday, closing at $160.95 and lifting the rocket‑AI group’s market value to about $2.1tn. The debut, the largest ever, placed the company as the world’s sixth‑largest public firm and propelled Elon Musk’s net worth past the trillion‑dollar mark. More than $80bn of stock changed hands in a single session today for investors worldwide now.

The IPO raised $75bn on Thursday, with a greenshoe option that could push proceeds to $86bn. Orders topped three times the supply, drawing asset managers, sovereign wealth funds, hedge funds and retail investors. Individual investors alone placed over $100bn in orders and received roughly a quarter of the allocation, while Citadel Securities flagged record‑high participation in the pre‑market auction today.

Musk owns about 42% of SpaceX, valuing his stake at more than $800bn; combined with his $280bn Tesla holding, his wealth now exceeds $1tn, roughly a third of the FTSE 100 market cap. Proceeds will fund Starship development, a Mars colony, lunar ventures and a network of orbital AI data centres. The listing also primes Anthropic and OpenAI for trillion‑dollar IPOs.
