Why it matters

Public, a New York City-based brokerage founded in 2019, began rolling out AI Agents on March 31, 2026, enabling investors to automate trading strategies, monitor markets in real-time, move money, and execute trades across stocks, ETFs, options, crypto, and bonds without manual intervention[1][2][4][8]. Users define intents via natural language prompts (e.g., buying protective puts on oil spikes, cash sweeps to higher-yield bonds, or 20% stop-loss orders), with AI asking follow-up questions to refine triggers, timing, and conditions before activation[1][2][4]. Agents operate securely within Public's financial-grade infrastructure, offering full transparency via logs, trading history, and user controls to pause, edit, or stop at any time[2][4].

Key players include Public (self-styled "world's first Agentic Brokerage," managing billions in assets, backed by over $400M from Accel and Tiger Global) and co-founder/CEO Yannick Ling (noted in prior AI announcements)[2][4][6]. The feature builds on Public's AI integrations since 2023, including a 2025 research assistant and November 2025 "Generated Assets" launch previewing agentic tools, with early 2026 plans for automated cash investing, dip-buying, and tax-loss harvesting[4][6][9].

This advances investing from manual orders to "intent-based" automation, shifting users from screen-glued monitoring to AI execution[2][4][8]. Newsworthy now amid rising AI adoption in finance—sparking market selloffs in sectors like asset management over replacement fears—and as the first brokerage to deploy such agents, positioning Public competitively while live for select users with a waitlist[2][4][5].
