Private Stock Market Excludes Public Investors
There's a big change happening in the stock market.
Companies are waiting much longer before they sell their stocks to the public.
Instead, they're raising money from a small group of very wealthy investors.
This means that regular people miss out on the big profits that come from investing in these companies when they're still growing.
For example, companies like OpenAI and SpaceX have raised billions of dollars from just a few investors.
Some people, like the chairman of the SEC, think this isn't fair and want to make it easier for everyone to invest in these companies.
But others worry that regular investors might get into trouble because private companies don't have to share as much information as public ones.
OpenAI raised $40 billion in a private funding round available only to a select group of wealthy investors.
The number of public companies in the U.S. has halved since the late 1990s, limiting investment opportunities for the general public.
Companies are waiting longer to go public, with the median age increasing from 6 years in 2000 to 14 years today.
Private companies like SpaceX and Figure AI have seen significant valuation increases through private funding rounds.
SEC Chairman Paul Atkins is advocating for opening up private markets to a wider group of investors to reduce wealth disparity.
