Opendoor: Is a Monopoly Forming?

Real estate is one of society's largest, oldest industries and has managed to resist significant disruption for many decades. In recent years, companies like Opendoor Technologies (NASDAQ: OPEN) have been attempting to improve the homebuying process with iBuying, where companies buy homes and resell them on the market. Opendoor's largest competitor, Zillow (NASDAQ: ZG) (NASDAQ: Z), recently quit iBuying, causing investors to question whether the business model can work.
