The 2023 Mega 1000 reveals how production continues to concentrate among the nation’s largest brokerages. This article presents a digest of the data behind that trend.

On April 25, T3 Sixty released the sixth annual Mega 1000, a ranking of the nation’s 1,000 largest brokerages by sales volume, and its 100 largest brokerages by transaction sides and agent count.

The 2023 report reveals a years-long trend of concentration of brokerage production among the nation’s largest brokerages. Leaders in all areas of the country feel this trend, but analyzing the Mega 1000 numbers shows just how big it is and some of the ways brokerages are finding ways to grow.

This article spotlights the trend and presents some of the numbers and data behind it.

Mega 1000 Production Growth

Between 2017 and 2022, the overall real estate brokerage market saw sales volume grow 42.7% and transaction sides actually drop 8.7%.

Mega 1000 brokerages, however, saw sales volume grow nearly twice that amount at 78.1% growth and transaction sides grow 25.0%.

Just looking at the nation’s 10 largest brokerages, that segment of the Mega 1000 saw the biggest gains in that six-year span: 135.7% growth in sales volume and 48.4% in transaction sides.
