International Team Wins Zillow’s $1 Million Prize for Improving Zestimates

The winning trio, from the U.S., Canada and Morocco, teamed up in the final round of the contest.

After nearly two years of competition among more than 3,800 teams from 91 countries, Zillow awarded the $1 million Zillow Prize in the contest to improve the accuracy of the Zestimate. The winning team beat the Zillow benchmark model by approximately 13 percent. As a result of these improvements, their work will help push the Zestimate’s current nationwide error rate of 4.5 percent to below 4 percent.
