Shared office provider, WeWork, has filed paperwork to enable it to list its shares on the US stock market as it seeks further funds for expansion.
Founded in the US in 2010, WeWork is already London and New York's largest private office occupier.
But it has yet to make a profit, with losses last year doubling to USD1.9 billion.
The firm's business model is based on short-term revenue agreements and long-term loan liabilities.
Ratings agencies have given it a "junk" or risky credit score because it has borrowed heavily to fund its expansion.
Despite this, the firm - which operates in 600 cities globally - was valued at some USD47 billion by private investors when it raised fresh funding in January.
