Budgeted CAT costs and allocation
The Budgeted CAT Costs for the July 1–December 31, 2025 period are $60,726,412. CEBBs collectively will be responsible for one-third ($20,242,137.33) of those Budgeted CAT Costs, and CEBSs collectively will be responsible for one-third ($20,242,137.33).
New CAT fee: $0.000009 per share
Starting July 1, 2025, Nasdaq will charge Industry Members who are CAT Executing Brokers a fee of $0.000009 per executed equivalent share through December 31, 2025. This fee replaces the prior CAT Fee 2025-1 (which had a rate of $0.000022 per share).
First invoices billed in August 2025
Brokers who are CAT Executing Brokers (CEBBs and CEBSs) will receive their first monthly invoice for the new CAT Fee 2025-2 in August 2025, and that invoice will be calculated based on their transactions as executing brokers in July 2025. The fee will be charged monthly for the July–December 2025 period.
Brokers may pass fee to clients
The filing states that CAT Executing Brokers may, but are not required to, pass CAT Fees through to their clients, and those clients could in turn pass fees to their clients until ultimately imposed on the account that executed the transaction. That means investors could see trading costs reflect the new CAT Fee 2025-2.
