Top 20 Private Equity Firms Worldwide
Private equity firms play a major role in the global economy by investing in private companies, acquiring listed businesses, financing corporate transformations and supporting long-term growth.

This selection brings together 20 prominent private equity firms with significant international reach, substantial investment platforms or distinctive expertise in buyouts, growth equity and private markets. It includes large diversified investment groups as well as firms focused on specific strategies.
