Apollo Global Management acquired 55% of Atlético de Madrid for $2.7B enterprise value, marking the largest PE sports acquisition in European football history. The deal includes €100M capital deployment for Ciudad del Deporte stadium infrastructure and expands the board from 5 to 11 seats, cementing operational control. Per Matchex data, mega-cap sports acquisitions above $2B remain concentrated in North American franchises and soccer media rights; this represents a structural shift toward consolidated European club ownership by institutional capital.
