California Stock Exchange's architecture is built around a single rule: no single desk can alter the record. Matching, clearing, and settlement live in three separately governed layers so the transparency and independence demanded by regulators and capital markets are preserved throughout.
In modern capital markets, a back-office statement isn't enough. California Stock Exchange backs every execution with a secure, independently verifiable settlement record - not a PDF you have to take on faith.
Orders and quotes stream into the matching engine and execute on a transparent, price-time-priority order book.
Real-time surveillance detects anomalies and flags potential market abuse as it happens.
Clearing & risk settles each trade instantly and captures it in a secure, independently verifiable record.
Members, regulators, and custodians can independently verify any settlement for themselves - no single desk to trust.
The record no single desk can edit. Every settlement is captured in a secure, independently verifiable record with segregated governance, operated under regulatory oversight. Regulators, custodians, and members can verify the record for themselves.
A regulated, independently audited settlement record with segregated governance. No single desk - including any one at the exchange - can rewrite settled records.
Role-based access, activity logs, and rich queries make the settlement record auditable from execution to finality.
Every settlement is independently verifiable - the record either exists at the timestamp claimed, or it doesn't.
Because settlement governance is segregated, every historical settlement remains verifiable even if any one part of the exchange were to fail.
California Stock Exchange scales from a single listing or trading-membership onboarding to full multi-market participation across equities, digital assets, and private markets - at a cost that works for small-cap, high-growth issuers.

Three layers. One immutable record.
"California Stock Exchange doesn't just report trades; it proves they were fair. No layer can alter another - the transparency and independence demanded by regulators and investors are maintained throughout."
Answers to the most common questions members, issuers, and regulators ask about California Stock Exchange.
No. California Stock Exchange connects to the systems you already have through standard market-data and order-entry interfaces - your OMS, EMS, and custody stack stay in place. Our role is to match, clear, settle, and record trades, not to replace your front office.
List a single security, or onboard for full multi-market participation. Either way - the record is independently verifiable.
