I would venture to guess that most of the money is/will Federal money that the State gets now for handling cases involving tribes. They will pass it on to tribes or Feds will send directly.
A month or so ago the Alaska Supreme Court ruled on case that basically gave the tribes the same type on sovereignty that tribes on reservations have. 
Previously, Alaska has been/is a PL 280 State with the exception of Metlakatla,which meant the State had jurisdiction. Last year or so the State signed agreements with two tribes to have jurisdiction over low level crimes.The other "signal" is a few tribes that have been asking for land to be put into Trust by the Feds. This has been creeping up because the tribes want the sovereignty status and the state wins by saving money.
It is going to take a tremendous amount of training before most of the tribes will be ready to go full force, but hopefully it will happen. 
The tribes want autonomy and their sovereignty like the tribes in non-PL280 states.
