Someone [reported](https://www.reddit.com/r/fidelityinvestments/comments/1scwoco/payment_for_order_flow/) this yesterday over at the fidelityinvestment sub. Looks like it's something new.
Fine print from Fidelity's March 2026 brokerage statement:
>Payment for Order Flow: Fidelity Brokerage Services LLC ("FBS") receives remuneration, compensation, or consideration for directing orders particular broker/dealers or market centers for execution.
