Michael Klein
Net worth: ~$6.9B (Bloomberg Billionaires Index, 2026 estimate)
Who they are
Michael Klein co-founded KKR in 1976 and is the firm's longest-tenured operating leader; he has served as Managing Director and, since 2022, as Co-Chairman of the Board alongside co-founder George Roberts. KKR is one of the largest alternative asset managers in the world, with assets under management of approximately $758 billion as of Q1 2026. Klein's career spans four decades of private equity, from the first leveraged buyouts to today's multi-strategy platform.
Why they matter
Klein is one of the original architects of modern private equity and the last of the 1976 founding group still deeply involved in the firm. His perspective on four decades of market cycles is unique in the industry, and his co-chairmanship anchors KKR's continuity through a multi-generational leadership transition.
The AI angle
KKR has been an active investor in AI infrastructure and software, and its global platform spans the data centers, power, and enterprise software that the AI buildout depends on. For AI strategists, KKR's relevance is as a large, diversified sponsor positioned across the physical and software layers of the AI economy.
