The co-working firm, once seen as the future of the office, has been plagued by financial problems.
WeWork has filed for bankruptcy in the US, a move that follows years of struggle for the co-working company.
The firm reported liabilities of up $10 to $50bn (£40.5bn), according to a bankruptcy filing in the New Jersey federal court.
The filing gives WeWork legal protection from its creditors and more tools for negotiations with landlords.
WeWork, known for renting on flexible terms, was once seen as the future of the office.
But it relied on rapid growth to mask its steep costs.
« I am deeply grateful for the support of our financial stakeholders as we work together to strengthen our capital structure and expedite this process through the restructuring support agreement, » WeWork chief executive David Tolley said in a statement.
