The answer of totalSupply() on the USDC contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base (chain 8453), read from the chain's own public RPC endpoint https://mainnet.base.org at the latest block and scaled from the token's 6 decimals. It is the supply on this chain only, not the issuer's total across chains, and it says nothing about reserves. Anyone can make the same call and compare.
