Buybacks start with common markets on Arc mainnet. Until the buyback contract deploys there is nothing to buy with, so these read zero; after that they read live from the contract.

USDC is Arc mainnet's gas token. The treasury and market contracts aren't on Arc mainnet yet; they join this table when they deploy.
Who gets each fee
A 1% fee on every buy and sell. Collected so far on Arc mainnet: $0, since markets open after their audit.
