This wave of exits isn’t simply a statistical outlier, the firm says. More than ever, companies are relying on interim chiefs, and the short-term revolving door has become so common that the highest-paid corner office is increasingly looking like a “gig economy” job, Challenger says, adding: “2025 marks the rise of the CEO gig economy.”

CEOs as gig workers

Through June 2025, a staggering 33% of newly named CEOs had stepped into their roles on an interim basis, compared to just 9% during the same period last year. Many of these leaders, including veterans who navigated companies through the Covid-19 pandemic, are returning to guide firms on their own terms, choosing flexible, project-based tenures over the once-standard multi-year engagement.

“With growing uncertainty across the economy, shifting corporate values like DEI, the impact of tariffs, potential deregulation, evolving consumer behavior, and the rapid implementation of new technologies such as AI, identifying the right leader for long-term success has become increasingly difficult,” said Andy Challenger, labor and workplace expert at Challenger, Gray & Christmas.

Interim roles offer both organizations and executives a strategic edge: companies gain agility and fresh perspectives swiftly; executives gain exposure and maintain flexibility.

The perils of the C-suite gig economy

There are real risks to a gig-like approach to the corner office. Teams led by an interim or short-term CEO may struggle with trust, long-term cohesion, and cultural stability. “When teams know their leader could leave at any moment,” Andy Challenger notes, “it’s harder to build lasting cohesion or trust.” Frequent leadership turnover can disrupt culture, diminish morale, and spark higher employee attrition—particularly if staff feel their voices aren’t heard or priorities are in constant flux.

Another sharp trend is the even split between internal and external interim CEOs: 53% were selected from within the organization, while 47% came from outside. When interim roles become permanent, internal and external candidates fare equally: 20% of each ultimately landed the role long-term.

The surge in CEO gig work contrasts with another shift: the lagging rate of new women CEOs. Only 25% of new CEOs appointed in 2025 are women, down from 28% last year.

Industries with surging turnover

Some sectors have been especially hard hit. The government/non-profit space leads (or trails), with 256 CEO exits through June—1.6% higher than last year’s 252 exits through the first half. The space has seen the highest turnover in both years.

Then there’s a big drop to technology, with 138 CEO departures through June, one of the highest monthly totals of the year; the turnover represented a 16% increase from 2024 as well. Health care/products saw 121 exits, a 20% increase from 2024. Hospitals, a subset, saw 68 departures, up 3%. Financial firms had 76 CEO exits year-to-date, a 29% increase year-over-year.

This upheaval reflects broad changes—uncertainty, rapid tech shifts, pressure on traditional leadership models—that are turning the CEO role into something more fluid, flexible, and, increasingly, temporary. In this era of “gig economy” leadership, both organizations and executives face new rules—and new risks—in navigating the future of the C-suite.
