Deposit market share is measured at the county level from the FDIC Summary of Deposits, an annual branch-level filing as of each June 30. County data shows which institutions actually hold balances in a given market and how concentrated that market is — a question state-level totals cannot answer, because a bank can be small statewide and dominant in its home county.
Vault republishes public FDIC and NCUA filings without modification. Bank figures come from quarterly call reports; credit union figures from NCUA 5300 filings; branch and deposit market share from the FDIC Summary of Deposits. Data is free to access and free to cite, with no login or paywall. The same data is available to AI agents through a public Model Context Protocol server at vaultbot.ai/mcp.
