Money Map — US Capital Concentration

Money Map builds a unified picture of US capital concentration using public data from seven sources: USASpending.gov ($6.5T/yr in federal awards), SEC 13F filings (institutional equity holdings), FDIC call reports ($23T in banking assets), IRS Form 990 (nonprofit assets), DOL Form 5500 (pension funds), IRS Statistics of Income, and Census Government Finance.

The focus is on leverage points — nodes where a small amount of control governs a large amount of stock or flow. The output is a ranked, evidence-backed answer to: which ~50-200 entities, through ownership, lending, spending, and policy, shape the majority of US economic activity?

Analysis methods: Herfindahl index, PageRank, betweenness centrality, control-to-ownership ratios.
