Before the RDOF auction began there was a controversy about the FCC not having accurate service coverage data to determine what census tracts should be eligible for the program. The result was that something like $16 billion would be paid out in this first round of auction, and $4 billion was held back for a second auction to fill the gaps once we had more accurate data. Then the bidding actually went low enough that the FCC was able to cover all their first-round goals with just $9 billion, leaving $11 billion for the second round. My understanding is that any areas (and clawed back funds) that weren't serviced during the first round will go back into the pot for the next round.
