Best for

Brokerages, wealth firms and fintech apps seeking outsourced custody and clearing, API access and broad asset coverage.

Not ideal for

Firms needing published pricing, or advisors seeking a turnkey custodian that includes ready-made practice software.

Verdict

Apex supplies the systems behind investing apps and brokerages. Clearing, custody and trading sit on a real-time ledger in the AscendOS platform. Apex Clearing handles 24x5 trading for US equities and ETFs, and it also handles futures, options, mutual funds, fixed income and alternatives. Crypto is offered through the affiliate Apex Digital Assets, and prediction markets through the partner Kalshi. Apex reported assets under custody of $276 billion and 41 million brokerage accounts as of June 30, 2026, and in 2026 Cash App Investing transferred its clearing to Apex.

Developers receive SDKs for four languages, API documentation and a sandbox, so integration is straightforward for technical teams. The commercial side and diligence both take work: prices are not published, and FINRA BrokerCheck shows 8 arbitrations and 50 regulatory event disclosures on Apex Clearing, and buyers should read the record in context, as this clearing firm has been registered since 1983.
