Welsh Rugby Union interim chief executive Nigel Walker says the four professional sides in Wales will receive the first instalment of money from the new Professional Rugby Agreement within the coming days.
The regions have been waiting on payment since March, when a new six-year framework between the WRU and the regions was agreed.
At the time of the new PRA being signed, it was announced that some key features would be "reliant on certain external approvals related to existing loan arrangements", with that approval being required from organisations including the Welsh Government.
