BetBright will donate £10,000 to the Injured Jockeys Fund in either Britain or Ireland, depending upon the outcome of the BetBright Cup at next week's Cheltenham Festival.
The competition pits Britain and Ireland against each other, with whichever country sending out the most winners being crowned the Festival champions.
BetBright will give the cash to the winning side's IJF, with the firm's chairman Rich Ricci delighted to be supporting such a worthy cause.
He said: "The prize-money is a new feature added this year, the Injured Jockeys Fund is such an incredible charity that caters to the enhanced care, rehabilitation and welfare of jockeys past and present.
"We could not be more proud of supporting such an organisation and look forward to seeing the amazing work they do now and into the future."
Ex-England cricketer Phil Tufnell will captain the British side this year with TV personality Hector O'hEochagain assuming the role as chief of the Irish side once more.
