With a massive built-in user base that can be encouraged to try out the Facebook Marketplace, Facebook is positioned strongly to disrupt the Craigslist monopoly for online classifieds. The Craigslist decision not to enter the app space may be contributing to Facebook Marketplace's growth as the feature now appears as a permanent icon along the bottom of the Facebook app.
Other dedicated online marketplaces must also be following the growth of the Facebook Marketplace. As Facebook users gravitate to the Housing category and the Vehicles category sites like zillow.com and cars.com will be paying close attention.
