The data supplier signed the original deal in 2018, acquiring official rights to the PGA Tour’s data for betting purposes across all events on its schedule.
The expanded deal provides IMG Arena with exclusive access to live, shot-by-shot match and event data.
Freddie Longe, SVP and Managing Director of IMG Arena, said: "As the sports betting market in the US evolves, extending our relationship with the PGA Tour is an important next step for IMG Arena.
"We continue to feel golf has the audience, interest and following to become one
of the leading in-play betting sports globally."
The spread of legalised sports betting in the US has led to several exclusive deals between the North American major leagues and data suppliers.
However, these were called into question when earlier this year a Sports Handle article claimed Sportradar had pushed operators for integrity fees on the NBA and MLB’s behalf.
The debate over integrity fees is still ongoing and could potentially see operators
charged a percentage of sports betting handle.
