CME’s October release reports micro equity-index contracts at 50% of category volume and a separate $313.9bn rolling average of customer collateral. Contract counts, economic exposure and collateral are different measures.
Official October 2026 reports put Cboe Global FX average daily notional at $60.388 billion and CME's EBS spot FX at $62.3 billion. The apparent closeness and similarly reported annual growth conceal different trading books, reference periods and methods. The comparison creates a reproducible benchmark, not a ranking of execution quality or global market share.
Reconstructing the first half shows that Q3 generated a larger share of the fee increase than of the contract-volume increase. A lower average fee rate still offset part of the volume benefit.
CME, Cboe, Nasdaq and ICE all reported strong growth in information-oriented businesses. A line-by-line reconstruction shows why adding their headline categories mixes feeds, connectivity, indices, workflow software and execution services.
The exchange operator’s largest asset had an equal liability; the footnotes separate restricted clearing resources, retained interest, default capital and corporate capacity.
CME’s Q3 collateral-earnings line equalled 80% of company revenue, yet a matched $1.269bn distribution expense left an analytical residual of $122.7m. The underlying $139.1bn Federal Reserve balance was clearing collateral, not corporate cash.
