Clear Street — Modernizing the brokerage ecosystem
Quick links
Broker-Dealers and Market Makers
Whether agency, omnibus or fully disclosed, broker-dealers rely on Clear Street for flexible clearing, financing and execution infrastructure.
Built for Broker-to-Broker Scale
Many broker-dealers operate on legacy clearing stacks with heavy reserve/computation workflows, fragmented routing and thin coverage during spikes. Clear Street’s cloud-native ledger unifies execution, clearing, financing and reporting, delivering STP, elastic capacity and faster product/exchange onboarding. Use us as carrying broker, an executing broker to extend venue/algos/desk coverage or clearing broker for your market making and prop units.

Common questions
Simple answers

Prospective clients can get in touch with our sales and onboarding team via our Contact page. A representative will reach out to discuss your execution, financing and clearing needs.
What makes Clear Street different?
Clear Street’s mission is to give every sophisticated investor access to every asset, in every market, through a unified platform built for speed, transparency and scale.
We give our clients the technology, tools and service once reserved for the largest institutions, rebuilt with modern infrastructure. Our single, cloud-native, end-to-end capital markets platform powers investor growth today and is transforming how they can interact with markets tomorrow.
Do we keep the client relationship if Clear Street carries or executes our flow?
Yes. You retain client ownership; we operate as carrying/executing counterparty behind the scenes with white-label reporting and segregated entitlements for supervision and audit.
How do you handle peak volumes and market changes like T+1?
Our cloud-native rails deliver high STP and uptime and elastically scale during spikes. During T+1, our unified ledger absorbed the shift to shorter settlement without lengthy rebuilds. Other instances of volatile markets, such as the effects of global trade uncertainty in Spring 2025, have further proved our model’s resiliency as volumes spiked significantly with no material impact on clearing timelines.
How do you onboard joint back-office (JBO) relationships?
We run a structured program: confirm JBO eligibility and account structure, align margin policy (including A6 where applicable) and set entitlements/supervision and pre-trade controls. In parallel, we stand up connectivity (FIX/API, drop copy), clearing numbers and CMTA details and wire books and records plus daily reserve/net-capital files. We then parallel-test order flow, margin and settlement, and cut over in phases with SLAs.
