Wall Street funds are building cash positions in preparation for potential initial public offerings (IPOs) from SpaceX, OpenAI and Anthropic. The source says SpaceX is being valued at $1.5 trillion to $1.75 trillion. It also says FTSE Russell (global index provider), Nasdaq (U.S. stock exchange operator) and S&P Dow Jones (index provider) are accelerating fast-track index inclusion rules. That matters because companies added quickly to major stock indexes can attract automatic buying from passive funds (investment vehicles that track indexes), which typically purchase shares to mirror benchmark weightings after a listing.
