The Women’s Tennis Association has announced a long-term partnership with Mercedes-Benz which has the potential to be the largest in women’s sport.

The German car manufacturer will become the premier partner of the WTA and pour $50m (£37.5m) per year into women’s tennis for up to 10 years.

The deal has been described as the “most significant” in the WTA’s history, and could ultimately be worth up to half a billion dollars (£375m).

The National Women’s Soccer League in America signed a $240m (£180m) four-year media rights deal in November 2023, while Nike has invested $350m (£262m) across multiple women’s football leagues.

Announced on Wednesday, the WTA deal will help with the tour’s commitment to have equal prize money at events where both men and women feature by 2027 and at non-combined events by 2033.

Equal prize money was one of the key goals when the WTA was founded in 1973.

American tennis great Billie Jean King, who founded the WTA and was its first president, said the deal shows the tour “continues to lead the way in women’s sport”.

“Women are making their mark now and it’s just beginning,” she told BBC Sport.

“Equal prize money is so important and sends a really strong message.

“Can you imagine being a kid today, looking at all the different opportunities?”
