Robinhood vs. Public vs. eToro: Comparing Agentic Trading Platforms

eToro takes a fundamentally different approach: instead of building and offering its own agent, it gives you the connection layer to bring your own. You link a custom AI agent, one you've built or sourced from a third party, to a dedicated sub-portfolio through a scoped API key, with a minimum investment of $200 to fund it.

This is the option built for a more technically confident user. Strategies can range from scheduled rebalancing to signal-reactive trading tied to specific events like earnings releases, but building or evaluating that agent is entirely on you. eToro isn't vouching for the agent's quality the way Robinhood or Public are vouching for their own; it's providing the pipe and letting you decide what runs through it.

Interactive Brokers took a deliberately more conservative path when it introduced its AI feature in June 2026. Rather than autonomous execution, IBKR built a semi-automated "human in the middle" system: the AI researches, analyzes live market conditions, and recommends, but every single trade requires your explicit approval before it executes. Coverage is limited to equities and ETFs.

If the idea of an AI placing trades without your direct sign-off makes you uneasy, and for most traders it reasonably should, IBKR's approval-required model is worth serious consideration over any of the three fully autonomous options above. It captures much of the research and monitoring benefit of an AI agent while keeping a human as the last checkpoint before capital actually moves.

Robinhood is the stronger choice if you're already a Robinhood customer, want the AI feature built into an app you use daily, and are comfortable being an early user of a beta product as Robinhood works out the rough edges.

Public is the stronger choice if granular, explicit permission control matters more to you than convenience, and you want to see exactly what you're authorizing before the agent can act.

eToro is the stronger choice if you already have, or are capable of building, your own trading agent and want a broker that will connect it to real capital without imposing its own agent's logic on top of yours.

Interactive Brokers is the stronger choice if you want the research and monitoring benefits of an AI system without giving up final say on every trade, which, for most active traders, is the more defensible starting point.

For most day traders reading this, that last option deserves more weight than the marketing around "fully autonomous" trading tends to suggest. Removing yourself entirely from the execution decision is a significant step, and it's worth taking only after you've validated how an AI agent actually behaves with real money on the line, in an approval-required setting first.

Choosing the right platform doesn't eliminate the underlying risk this entire category carries. All three broker-built agents, and the eToro bring-your-own-agent model most of all, run on MCP-based connections that inherit the same documented security weaknesses covered in Connecting Claude or ChatGPT to Your Brokerage: permission scoping that varies wildly by implementation, limited standardized activity logging, and an attack surface that security researchers have flagged as actively exploited elsewhere in the MCP ecosystem. Account isolation and confirmation screens reduce the blast radius of a problem. They don't eliminate the underlying protocol-level risk.
