About Public
What is Public?
Public is the world's first agentic brokerage—a multi-asset investing platform that lets you trade stocks, bonds, treasuries, options, crypto, and ETFs all in one place. It combines AI tools (like Agents, Generated Assets, and earnings call summaries) with traditional brokerage features to help both active traders and long-term investors make smarter decisions.
What problem does Public solve?
Investors often struggle to analyze market moves, manage complex portfolios, and find low-cost trading. Public solves this by embedding AI into every part of the investing experience—from automated portfolio management via Agents to instant research answers on any stock. It also offers industry-leading margin rates (as low as 4.90%) and options trading rebates of $0.06–$0.18 per contract, reducing costs for active traders.
Who is Public for?
Public is ideal for active retail investors, options traders, and crypto enthusiasts who want advanced tools without institutional pricing. It's also great for AI-curious investors who want automated insights and programmatic trading via its API. It may not suit buy-and-hold beginners seeking a simple, no-frills app, as the platform emphasizes AI and active strategies. Common use cases include day trading options, building custom AI-generated indices, and earning yield on cash (3.30% APY on High-Yield Cash Account).
