Public.com Lets AI Agents Automate Bank Transfers

Why it matters

Public.com is trying to turn brokerage automation into a product wedge against larger consumer trading apps. Bank-linked transfers make its AI Agents more useful, but they also move the risk boundary from research and alerts into automated cash movement that investors will need to understand before enabling.

Public.com, the New York-based investing platform founded in 2019, is adding dynamic bank transfers to its AI Agents, extending its automation pitch beyond portfolio rules and into cash-flow management.

The company has spent the last several years expanding well beyond commission-free stock trading. Its platform now offers access to stocks, fractional shares, ETFs, options, cryptocurrencies, bonds, Treasuries, IRAs, high-yield cash accounts, direct indexing, social features, research tools, and AI-powered investing tools.

Public.com has recently described itself as the world's first "Agentic Brokerage," a framing that points to a broader shift from merely offering investment products to automating investment decisions and workflows. The new bank-transfer capability is a concrete example of that strategy: users can set rules in plain English that monitor balances, schedules, or market conditions, then move money between linked accounts when those conditions are met.

In a short product demonstration, the company shows a user creating an automation that says: "Anytime my brokerage cash drops below $5,000, automatically transfer $1,000 from my connected bank account."

The demo also shows other fund-management workflows, including automatically transferring cash into a brokerage account when balances fall below a threshold, sweeping excess funds from checking accounts into investment accounts, moving money into high-yield cash products on a schedule, and funding market purchases during specific events, such as significant intraday declines in SPY.

The update moves Public.com's AI Agents from portfolio management toward liquidity management across banking and brokerage accounts. For retail investors, that matters because sophisticated automation has historically required a mix of financial institutions, third-party software, spreadsheets, or custom code.

Public.com is trying to collapse that complexity into a conversational interface. Instead of manually moving money between accounts or configuring rigid banking rules, users can describe what they want to happen and have AI agents monitor balances, schedules, and market conditions on their behalf.

The implications go beyond convenience. Automated cash management can help investors keep idle cash invested, maintain minimum account balances, systematically buy market dips, or enforce long-term investing rules without constant manual intervention. For investors prone to procrastination, FOMO, or market-timing mistakes, rule-based automation may improve consistency.

The launch also fits a larger fintech shift: AI moving from an information layer to an execution layer. Many brokerages now offer AI-assisted research or portfolio insights. Public.com is pushing toward agents that can monitor conditions and execute approved actions, bringing some of the workflow automation long used by professional investors closer to retail accounts.

The company has raised more than $400 million from investors. Its most recent financing, a $135 million Series D-2 announced in December 2024, included $105 million in equity financing and $30 million in debt led by Accel. Other backers include Greycroft, Lakestar, Tiger Global, and individuals including Will Smith, Tony Hawk, Maria Sharapova, and The Chainsmokers.

Public.com operates as a registered broker-dealer and has continued to broaden its product lineup as competition among retail investing platforms intensifies. The bank-linking feature is less about a single transfer tool than about establishing AI agents as a trusted operating layer for personal finance.

That vision is still early. Investors remain responsible for the rules they create, and all investing carries risk. Public.com says it emphasizes transparency through activity logs and user approvals.

Still, the direction is clear: brokerages are beginning to compete not only on assets, fees, and research tools, but on who can build the most capable financial agents. Public.com is betting that the future investor will not just use software. They will manage a team of AI agents working on their behalf.
