Alpaca Scaling as Trading Infrastructure

This volume jump shows Alpaca is scaling like infrastructure, not like a consumer brokerage. Each new fintech partner can bring thousands of end accounts onto the same APIs, so growth comes from adding distribution nodes rather than winning users one by one. Once Alpaca moved to self clearing, that extra volume became more valuable because it could keep more of the fees tied to execution, margin, and cash balances.1 2 3 4 5

• Alpaca sells a broker in a box. A partner plugs in trading, account opening, reporting, and back office flows through APIs, while Alpaca handles order routing, clearing, settlement, and compliance underneath. That makes it easy for a neobank or regional fintech to add U.S. stocks without building a brokerage from scratch.1 4 5
• Self clearing changed the economics. Before April 2024, a third party would take part of the trade stack. After joining DTCC directly, Alpaca controlled the books and records and the settlement layer, which supports better unit economics and faster product rollouts like options and 24/5 trading.2 4 6
• The closest comparables are DriveWealth and Apex. Apex has bigger legacy scale in clearing and custody, while DriveWealth is the nearest API first rival. Alpaca is differentiating with faster developer integration, more global partner coverage, and a broader product set that now spans equities, options, crypto, and fixed income.5 7 8 9

The next step is turning trading volume into a wider financial stack. As Alpaca adds more markets, more asset classes, and more always on trading windows, it becomes harder for partners to switch because the API is no longer just for stock orders, it is the operating system for their investing product.3 6 8
