Reddit founder Alexis Ohanian has bought a stake in Women’s Super League champions Chelsea, the club have confirmed.

Ohanian, who is married to tennis great Serena Williams, will have a seat on Chelsea Women’s board after purchasing a 8-10% share, believed to be worth around £20m.

“This is a landmark day in the history of Chelsea Women and for women’s football in Europe and beyond,” said Aki Mandhar, chief executive Chelsea Women.

“This investment is validation of the club’s past success but more importantly it is yet another proof point in the market of the persistent growth and potential of women’s football.

“There is no greater champion of investing in the future of girls and women’s sports than Alexis, and we are incredibly proud to welcome him to the club.”

Ohanian, 42, has invested in women’s football previously, as the largest shareholder in American club side Angel City FC until it was sold in 2024 for £192.3m – the highest price for a women’s sports team until this deal.

“As Founding Control Owner of Angel City FC, I’ve seen the opportunity to create and grow a worldwide brand within women’s football, and I’m confident Chelsea FC Women is the next global women’s sports brand,” said Ohanian.

Ohanian had announced news of his investment on Wednesday and posted images of Chelsea kits with the names of his children, Olympia and Adira, on the backs.
