"That sounds like a lot of money for the tier-one market but they generate 95 per cent of the revenues in a World Cup," Brett Gosper, World Rugby chief executive, said.
The remainder of the money was set to be invested into tier-two and tier-three countries and to develop the game in untapped markets such as Germany, Brazil, China, India and the USA.
Ireland was knocked out of the equation to host the tournament early in the voting, and France beat out South Africa by a margin of 24-15 in the second round.
While New Zealand Rugby voted for South Africa both times, they will now profit handsomely from the decision to host the tournament in the European nation.
