From a transaction volume standpoint, the pandemic of 2020 was not kind to iBuyers. Overall volumes and market share are set to drop by 50 percent compared to 2019, a reflection of the iBuyer business model coming to a complete standstill followed by a slow recovery.

Segment market share continues to shift among the big four iBuyers. Opendoor's share of the market is down to 50 percent -- a gradual decline from 2018 as new players entered the market and the overall segment grew rapidly. Zillow has made a strong entrance while Offerpad has maintained its position.

The pandemic of 2020 affected real estate in a variety of unprecedented ways. The drop in iBuyer market share and transaction volumes isn't a failure of the model, but it is a result of the model. The iBuyers face a slow climb back to the levels of 2019, as they conservatively ramp up operations in a new, uncertain housing market.
