The co-founder and CEO of WeWork, the fast-growing co-working startup, has sold and borrowed hundreds of millions of dollars in transactions involving his shares in the company, according to a report in the Wall Street Journal on Thursday.

Adam Neumann, WeWork's largest single shareholder, has cashed out some of his stake in the company in recent years, while also borrowing money against his holdings, according to the report. The news of Neumann's transactions, which the WSJ said totaled $700 million, comes as the office-space giant prepares for a highly anticipated IPO.

WeWork confidentially filed to go public in April and was valued at $47 billion in its most recent private funding round, in January.

Neumann sold some of his stake through stock sales during several rounds of financing, according to the report, which said it was unable to confirm his current stake. The WSJ said Neumann used some of the proceeds to exercise his stock options and purchase more shares in WeWork. Neumann, 40, has also used the money to buy five private residences, as well as to invest in commercial real estate and startups, the report said.

It is not uncommon for founders and other early stakeholders of private companies to cash out some of their holdings during financing rounds to entice large investors. But selling sizeable stakes ahead of a planned public offering sends Wall Street mixed signals about the founder's confidence in the company's long-term viability on public markets. According to anonymous sources quoted in the WSJ report, Neumann's borrowing against his stake proves he is confident in the co-working giant's long-term success.

The company has raised $10 billion in venture and debt funding since it was co-founded in 2011. The company's financials have come under scrutiny in the run-up to its public debut as it struggles to turn large real estate investments into a profitable business model.

WeWork declined to comment.
