Uncertainty and mixed signals have carried over to the second quarter of the year in IT staffing, and the question on the minds of many now is, “What will happen in the second half?”

While that question remains to be answered, something that almost everyone in the industry can be certain about is that 2022 (particularly the first half of the year) was a good one. And that was reflected in our recently released Largest IT Staffing Firms in the US: 2023 Update report.

The report lists 71 companies with greater than $100 million in US IT staffing revenue, for which combined total $35 billion in revenue, or roughly 83% of the entire US IT staffing market. Seven companies had greater than $1 billion in IT staffing revenue. The largest three were TEKSystems (Allegis Group), Insight Global and ASGN — combining for 24% of the market.

Eleven of the companies included in this year’s report (15% of the companies on the list) did not appear in last year’s report. And this was despite some consolidation among a couple of large players in the industry; in 2022, Adecco acquired Akka, and Motion Recruitment acquired Matrix Resources.

A marketplace with 71 companies with $100 million or more in revenue is a byproduct of digital transformation-fueled growth in IT staffing in the last two years (per our April US Staffing Forecast, 17% in 2021 and 16% in 2022) which consequently has led to higher bill rates.

The way 2023 is playing out so far, next year’s largest list might not show as much growth. After a May Pulse Report in which April IT staffing revenue was flat on a median basis, the July Pulse will be a good indicator for the trajectory we’re on for the remainder of the year. The Pulse Survey will open in the first half of July — visit our surveys page for more info.
