British Olympic silver medallist Matthew Hudson-Smith won $100,000 (£77,000) after winning the 200m at the first ever Grand Slam Track event on Saturday.
The event is the brainchild of Olympic legend Michael Johnson with the first of four meets taking place in Kingston, Jamaica.
Athletes are placed in 12 groups and compete over two races per meet.
The points totals from those runs determine the champion of each group.
The groups are split out into men’s and women’s short sprints, long sprints, short hurdles, long hurdles, short distance and long distance.
Hudson-Smith put himself in a great position to win his group after lying second in the standings after Friday’s 400m.
He then won it outright with a total of 20 points when he crossed the finish line in the 200m in 20.77 seconds.
“Great to get the first one, I’m really excited and grateful,” the Paris 400m silver medalist said.
“I’m getting to the end of my career so it’s time to start saving.”
Writing on social media alongside a picture with Johnson, Hudson-Smith said: “Won the golden ticket.”
Three more athletes headed home on Saturday with healthier bank balances, including USA Olympic star Gabby Thomas.
She backed up her 200m win with a second place in the 400m to top her group.
“I’m not sure I’ve ever been more tired in my life,” Thomas said.
“I heard them saying on the home stretch ‘$100K on the line’ and it really, really motivated me.”
British athlete Zharnel Hughes scooped $50,000 after he finished second in his short sprint group.
Grand Slam Track has been questioned after few fans in Jamaica attended the races over the weekend.
Vast swathes of empty seats could seen as the athletes took to the track.
Ahead of the races, Johnson told BBC Sport: “My objective is to create the opportunities that athletes have always wanted and to put them on a stage that is worthy of their greatness, with races that mean something.
“To do that you have to have the best competing against each other. That is what is compelling about the biggest sports in the world. That’s what we’re creating.”
Johnson and his fellow Grand Slam bosses will be hoping for a better turnout in Miami next month, before they head to Philadelphia and Los Angeles.
