Alpaca, a company specializing in brokerage infrastructure, has successfully raised $435 million, divided into $135 million in equity and $300 million in debt. This significant capital injection aims to expand its services into prime brokerage, positioning the startup to compete directly with established institutions like Goldman Sachs and Morgan Stanley.

Notably, Alpaca's technology currently facilitates the clearing of about 94% of U.S. equities and ETFs, serving as a backbone for several innovative tokenization projects, including those on Kraken's platform. Here, users can purchase fractional shares of traditional stocks through a crypto-native interface, with Alpaca managing the necessary clearing and settlement processes.

In the first quarter of 2026, Alpaca experienced an impressive fourfold increase in API trading volume, driven predominantly by AI agents, rather than traditional human traders. This shift reflects a broader trend in the industry, highlighting the growing role of AI in executing trades. To support this transition, Alpaca has introduced tools such as its Trading MCP Server, tailored for AI applications.

The fresh equity raised builds on a prior $150 million Series D round completed in January 2026, which valued Alpaca at $1.15 billion. With a total equity funding now surpassing $320 million, the company’s investor base includes prominent names like Drive Capital, Spark Capital, Tribe Capital, Horizons Ventures, and Y Combinator.

While this funding round does not introduce new crypto tokens, Alpaca remains focused on enhancing its operational infrastructure rather than chasing speculative asset launches. The substantial debt component is crucial for enabling margin lending services, which are capital-intensive and essential to the prime brokerage landscape.

The growing demand for AI-driven trading mechanisms illustrates a key shift in the market, demonstrating how innovative technologies redefine traditional trading practices and relationships.
