Alpaca Raises $50M Series B for API-Driven Stock Brokerage Platform

Alpaca announced a $50 million Series B funding round on September 1, 2021, for its API-first stock brokerage platform. The company enables fintechs and developers to embed commission-free stock trading, fractional share investing, and emerging crypto trading capabilities into their applications through its developer-friendly APIs. Alpaca's platform integrates with Plaid for account connectivity, streamlining the onboarding experience for end users.

The funding will be used to expand into multi-asset classes including cryptocurrency and to grow the platform's global reach. Alpaca's model removes the need for partners to obtain their own brokerage licenses or build trading infrastructure, embodying the BaaS approach applied to capital markets. The round followed closely on the heels of the Series B close and reflects strong demand for embedded investment infrastructure among fintech developers.
