Three listed exchange operators reported broadly flat transaction revenue in their most recent filings, while custody, staking services and subscription products grew as a share of the total.
The shift matters because the two revenue lines behave differently. Trading fees are cyclical and correlate with volatility; custody and staking fees accrue on balances and survive quiet quarters.
It also changes the regulatory surface. Holding client assets and operating staking services attract supervisory attention that a matching engine does not.
Margins on the service business are thinner than the headline suggests once insurance, audit and reserve costs are included, according to two of the three filings.
All figures cited here come from published financial statements. Where companies use non-standard segment definitions, we say so rather than blending them.
