A newly reported investment round has brought in $112.5 million for the Boring Company, the venture that billionaire techie Elon Musk created last year to build transit tunnels.
And most of those millions came from Musk.
Documents filed today with the Securities and Exchange Commission say 31 unnamed investors contributed to the funding round.
Musk himself put in more than 90 percent of the money, according the Boring Company. The company said the rest came from early employees, with no involvement by venture capitalists or outside investors.
