Hello, I'm Sam Fenwick and welcome to Business Daily from the BBC World Service.

Today we're asking, when will we see the first female billionaire athlete?

I'm optimistic that this will happen in the next, I'll say, 20 years.

This is not going to happen overnight.

There are currently four athletes who financial magazine Forbes say

are billionaires and all of them are men. In February, on Business Daily, we looked into those four

people and how they made their fortune. But it raised one big question. With women's sport on the

rise, how close are we to seeing a woman in that list? The female athletes who are coming as close to the men as possible are in tennis and athletics.

Serena Williams, she always comes to top, Nomiya Sarka as well, and then Simone Biles is in the US for athletics.

So today it's the turn of the women. We find out how female athletes at the top of their game are investing their money,

what's stopping them getting the same level of sponsorship as their male counterparts, and ask

what a woman getting to this level would mean for sport. I had a conversation with one of the

big three in tennis, his agent, his manager, who was saying, you know, his instruction from his

client was, don't take any risks. The instruction I got from Naomi is take risks. Don't be afraid to mess a few

things up. That's all coming up on today's Business Daily. Let's start by giving you an idea

of what some of the biggest stars in both men's and women's sport

are worth. There are four men who are billionaires according to Forbes. Basketball great Michael

Jordan is top of the list. He's valued at $3.2 billion. Then we have golfing legend Tiger

Woods who sits at $ 1.3 billion.

Third on the list is NBA star LeBron James. He's worth 1.2 billion.

And the most recent to join the list is Magic Johnson.

Also a basketball player, he's worth 1.2 billion.
