CEO Yoshi Yokokawa says monthly active API users have grown nearly 4x in six months, while tokenized equities on Alpaca reached $1.5B in assets under custody.
Alpaca says AI agents are already driving a sharp increase in activity on its trading infrastructure, with CEO Yoshi Yokokawa pointing to nearly 4x growth in monthly active API users over the past six months. The acceleration became visible in Q1 2026, when API usage surged nearly 4x quarter-over-quarter and monthly growth rates moved from single digits in Q4 2025 to about 30% in early 2026. The company attributes that shift to AI agents and has been expanding AI-native tools, including a Trading MCP Server, a command-line interface, and an open-source Skills Library. Alpaca said it now serves hundreds of clients in more than 40 countries, supports over 10 million brokerage accounts, and manages $1.5B in tokenized equities (blockchain-based stock representations) under AUC (assets under custody). On July 16, 2026, the company closed a $135 million equity raise led by Peak XV, lifting total financing to $435 million at an approximate $1.15B valuation. The round followed a $150 million Series D in January 2026. Alpaca also said revenue has doubled year-over-year for three consecutive years, as Yokokawa frames APIs (software connections between systems) as the core infrastructure for AI-enabled market participation across stocks, ETFs, options, crypto, and tokenized assets.
