Caixin: SpaceX IPO First Day Free Float Market Cap Could Be Between $440 Billion and $530 Billion

Odaily reported that Caixin published an article titled "SpaceX's $1.75 Trillion IPO Approaches: Who Can Buy and Is It Worth It?", which points out: Wall Street has never encountered a listed company with such a massive IPO scale while simultaneously having such a complex relationship with the U.S. government. Nasdaq has previously passed a new "Fast Entry" rule, allowing newly listed companies with a market capitalization ranking among the top 40 of the Nasdaq 100 Index to be quickly included in the Nasdaq 100 within 15 trading days after listing. This rule will officially take effect on May 1, 2026, and is also considered to be designed for the upcoming SpaceX IPO, while potentially paving the way for the listings of OpenAI and Anthropic, which may occur in 2026 or 2027.

Assuming SpaceX lists with a $1.75 trillion valuation and a free float ratio of 25% to 30%, the free float market cap on the first day of the IPO would be approximately between $440 billion and $530 billion. Based on the weight calculation of the Nasdaq 100, SpaceX would directly enter the top ten weighted stocks. According to market sources, the S&P 500 is also evaluating some form of "fast inclusion" plan, though details have not yet been disclosed. (Caixin)
