But as he prepares to tee off today in the Irish Open, McIlroy’s account is not set to benefit by even a cent even if he lifts the trophy following this week’s work.
If the Co Down golfer claims the first prize of £416,000 (€585,000), all of it will be donated to his own charitable foundation, which is hosting the tournament at Royal County Down.
“What I want to get out of it this year is just to raise a lot of money for the foundation for the cancer fund, and ultimately if I play well, and if I do well in the tournament, then all the money that I earn is going to go towards that as well,” he said.
“So I’m not really playing for myself this week. I’m playing for a lot of other people and it gives me an incentive to go out there and enjoy it and try to play well.”
The participation of world golfing superstars Rickie Fowler and Sergio Garcia in the tournament is believed to be down to McIlroy’s significant involvement in the event.
Yesterday, a host of celebrities, many of them from the Irish sporting world, took part in the pre-tournament pro-am.
Among those teeing off were the likes of snooker players Dennis Taylor and Ken Doherty, former rugby player Stephen Ferris, and newly retired champion jockey Tony McCoy.
The pro-am even gave Rory McIlroy the chance to bolster the charitable donations being made through the McIlroy Foundation.
At the pre-event dinner on Tuesday night, three men bid £150,000 to join Rory in a four-ball yesterday.
That money is to go to the Cancer Fund for Children.
