Timing is key for IPOs

British billionaire Sir Richard Branson's space tourism venture is set to go public by year-end and dozens more, including unicorns and tech stocks, are planning to raise funds in the capital markets this year.

Virgin Galactic is the first human spaceflight company with over 600 reservations for its first commercial flight to space. Branson needs funding in the race to space for his Virgin Galactic to take on Jeff Bezos’ (the world's richest man) Blue Ocean.
