SoftBank is reportedly weighing an investment between $15 billion and $20 billion, which would come from its $92 billion Vision Fund, a super-sized venture fund led by Japanese entrepreneur and investor Masayoshi Son.
WeWork declined to comment.
SoftBank already owns some 20 percent of WeWork. The firm invested $4.4 billion in the company in August 2017, $1.4 billion of which was set aside to help WeWork expand in China, Japan and Southeast Asia.
This August, WeWork raised another $1 billion from SoftBank in convertible debt. At the same time, WeWork disclosed financials to a handful of media outlets, sharing that its revenue had doubled to $763.8 million in the first half of 2018 as losses increased to $723 million.
SoftBank, for its part, seems to have a hankering for real estate tech. Not only has it become a key stakeholder in WeWork, but it has deployed significant amounts of capital to Opendoor, Compass, Katerra and others.
Last month, the Vision Fund backed Opendoor, a platform for buying and selling homes, with $400 million. The same day, it led a $400 million round for Compass, valuing the real estate brokerage startup at $4.4 billion. As for Katerra, SoftBank poured $865 million into the construction tech business in January.
WeWork, founded in 2010 by Adam Neumann and Miguel McKelvey, has raised nearly $5 billion in a combination of debt and equity funding to date. It was valued at $20 billion in 2017, though reports earlier this summer estimated its valuation would fall somewhere between $35 billion and $40 billion with additional capital from SoftBank. A $40 billion valuation would make it the second most valuable VC-backed company in the U.S. behind only Uber.
WeWork has more than 268,000 members across 287 locations in 23 countries.
