Sixth Street, the global investment firm, has acquired a majority stake in Sunderland AFC Women, marking its first UK football investment. The deal is executed through its Bay Collective subsidiary, a platform focused on building women's football clubs. Sunderland AFC retains a minority stake in its women's team.

This move expands Sixth Street's sports portfolio, which already includes partnerships with FC Barcelona, Real Madrid, the San Francisco Giants, and the Boston Celtics. Sunderland AFC Women becomes Bay Collective's second club, following Bay FC in the US National Women's Soccer League. The investment underscores growing institutional confidence in women's sport's commercial potential. Sixth Street co-founder Alan Waxman previously stated he expects professional women's teams to become national and global consumer brands. 10,000 fans attended Sunderland's recent derby against Newcastle United, demonstrating significant local interest despite broader challenges in women's football attendance.

The timing aligns with Bristol City Women's recent majority stake sale to Mercury 13.
