Co-founded by Yoshi Yokokawa (CEO) and Hitoshi Harada (CTO/CPO), Alpaca achieved unicorn status in January 2026 after raising $150 million in a Series D funding round, valuing the company at $1.15 billion. This funding, along with a $40 million line of credit, is intended to strengthen its global infrastructure and expand its regulatory footprint. Alpaca has expanded its product suite to include multi-leg options, fixed-income, and 24/5 US stock trading, and has reinforced its position as a full-stack brokerage infrastructure by becoming a member of the OCC, FICC, and Nasdaq Exchange in 2025.
