Spencer Stuart’s March 2025 CMO Tenure Study found average Fortune 500 CMO tenure rose to 4.3 years in 2024 from 4.2 in 2023, with most departing CMOs moving to equal or better roles. Separately, Forrester reported in August 2026 that 88% of B2B marketing organizations have adopted AI tools, even as leaders cite unresolved gaps in strategy and measurement.

66% of Fortune 500 companies had a C-suite marketing leader in 2024; the other third structure marketing across business units, combine it with other functions, or use hybrid arrangements.
When Fortune 500 CMOs depart, 65% are promoted internally or move to comparable or higher-level roles, and 10% become CEOs.
88% of B2B marketing organizations have adopted AI tools, but report gaps in strategy clarity, measurement capability, data infrastructure, and knowing where to apply AI.
