Alpaca Markets just closed a $135 million funding round led by Peak XV, and the thesis behind the check is pretty simple: the next wave of traders won’t be humans clicking buttons. They’ll be AI agents executing strategies across stocks, crypto, and tokenized assets through a single API.
The raise, which closed on July 16, 2026, is designed to accelerate Alpaca’s push into what the company calls “agent-first” brokerage infrastructure.
The numbers tell the story
Alpaca’s monthly active API users grew nearly 4x in the six months leading up to mid-2026, and the company attributes most of it to AI agents being plugged into its trading infrastructure.
The $135 million round follows an already substantial funding history. Alpaca raised $150 million in a Series D back in January 2026, which valued the company at $1.15 billion. Before that, a $52 million Series C landed in 2025.
