> A company can also sell its shares in the open market to raise capital following a direct listing without restrictions, typically after it has reported quarterly earnings.

With the market being this hot (IMO it's a bubble, but only time will tell), enough public investors are clamoring over IPOs that companies could likely get away with a direct listing like this.

It's needless to say a direct listing has never been done this way.
