The Race to Dubai event was first organized in 2009
Golf's largest prize is awarded during the end of year event of the European Tour in Dubai in November.
The winner will earn $ 3m net 2.3 million), an increase of $ 1.67 million on the amount won by the Englishman Danny Willett last year.
The goal is to encourage more big names to complete the race to Dubai.
Last year, number one Justin Rose died in the tournament at Jumeirah Golf Estates because he did not have the chance to overhaul Francesco Molinari for the general Race to Dubai title.
Only two players, Molinari and Tommy Fleetwood, still had the opportunity to win the season-long money list by the time players in the Middle East arrived for the final event.
The total prize fund remains at $ 8 million (£ 6.2 million), but the field is reduced from 60 to the top 50 on the money list. The distribution of prize money will be top-loaded to deliver the biggest winner's test for an individual tournament.
It is one of a series of changes announced by the European Tour for the highlight of the 2019 season. There are also significant increases to finish first at the Turkish Airlines Open and the Nedbank Challenge in South Africa.
The champion in Turkey takes home $ 2 million and the next week at Sun City the winner wins $ 2.5 million.
Once again, the total prize money for both tournaments remains unchanged, but the fields will be reduced, with 70 men at the Turkish event and 60 in South Africa.

Pelley added: "If this extra race to Dubai points had been available for the past five years, on average between five and 16 players would have come to our last event with a chance to race to Dubai. win, in addition to an average of 43 players at the end of the season have a chance of bonus pool money – both numbers considerably higher than in those years
"With the revised breakdown of the prize money and the extra Race to Dubai -points in place for 2019, this provides a huge boost for our players. "
Earlier, the top 10 finishers on the race to Dubai shared the bonus pool of $ 5 million, but now that sum will be split between only the leading five finishers.
