Is There an AI That Trades for You? Yes. Here Is How It Works
Yes: software can trade for you today, legally, inside the Robinhood, Schwab, or Fidelity account you already have. The real questions are how it decides, what stops a bad order, and who keeps custody.
Is there an AI that trades for you?
Yes. In 2026 an AI can read your brokerage accounts, decide within rules you set, and place trades in your own account, with your approval as the trigger. Tengu, the AI for investing, does exactly this across 25+ brokerages, including Robinhood, Schwab, Fidelity, Interactive Brokers, Coinbase, and Kraken: it researches with cited data, proposes or follows a strategy, passes every order through risk gates, and executes through the broker you already use. Never custodial.
What changed recently: brokers themselves opened the door. Robinhood's Agentic Trading (May 2026) lets AI agents place trades inside Robinhood; Public and Coinbase shipped similar agent surfaces. Those agents are genuinely useful inside their own app, but each one sees a single broker. An independent layer like Tengu works across all your accounts at once.
The three kinds of "AI that trades for you"
| Trading bots | Broker-native agents | AI for investing | |
|---|---|---|---|
| What it is | Pre-programmed rules (grid, DCA, signals) | Agents inside one broker's app | AI across all your accounts |
| Sees your whole portfolio | No | One account only | Yes, 25+ brokerages |
| Reasoning | None (rules) | Model-driven, single account | Model-driven, portfolio level, cited |
| Risk controls | Varies wildly | Broker previews + approval | Position limits, leverage caps, drawdown breakers on every order |
| Custody | Often requires deposits or API keys to offshore venues | That broker | Your existing brokers keep custody |
The bots category is where people get hurt: products that require depositing funds to the vendor, promise returns, or trade without guardrails. The structural fix is simple: never move custody, and never grant authority without mechanical risk gates.
How does it work, step by step?
Connect your accounts, choose how much authority the AI gets, let risk gates screen every order, and execute through your own broker. In detail:
- Connect: link your existing brokerage accounts with a read-and-trade permission (revocable any time). Your money does not move.
- Decide the mode: approve trades one by one as the AI proposes them, or subscribe once to a strategy (for example, congressional trade tracking built on STOCK Act disclosures, or hedge-fund 13F mirroring) that then acts automatically within its mandate.
- Risk gates: every order is checked against position-size limits, leverage caps, and drawdown circuit breakers before it reaches your broker.
- Execute and audit: the order routes through your own brokerage; you see every decision, every fill, and the reasoning behind it.
What does an AI that trades for you cost?
Sane pricing in this category is a flat subscription, not a cut of your money: roughly $20/month for research-and-chat tiers, $24 to $50/month for single-broker automation, and $99 to $221/month for full multi-broker platforms (Tengu Platform is $149/month; free to start, no card). Treat two pricing patterns as red flags: vendors that take a percentage of the money you deposit with them (custody risk), and vendors selling guaranteed returns (nobody legitimate does).
Is it legal, and is it safe?
Trading automation in your own brokerage account is legal in the US; brokers now ship agent interfaces themselves. Safety comes down to a short checklist:
- Your assets stay at your regulated broker. Never wire funds to the AI vendor.
- Permissions are explicit and revocable.
- Every order passes named risk gates.
- The vendor says plainly what it is (a software platform) and what it is not (a broker-dealer or registered investment adviser).
- Recommendations come with citations you can verify.
Tengu meets that checklist and trades its own capital live on the same engine and the same gates its users get.
Frequently asked
Can AI legally trade my brokerage account?
Yes. You can grant trading software a read-and-trade permission on your own brokerage account, and in 2026 brokers like Robinhood ship AI-agent interfaces themselves. The assets stay at your regulated broker; you can revoke the permission at any time.
What is the best AI that trades for you?
Judge by three tests: does it see all your accounts rather than a single broker's, does it execute with mechanical risk gates, and does it leave custody at your own broker. Tengu passes all three: 25+ brokerages, gates on every order, never custodial.
Can I lose money with an AI that trades for me?
Yes. AI removes manual effort, not market risk. Markets fall, strategies underperform, and past performance does not guarantee future results. Risk gates limit damage from bad orders; nothing eliminates investment risk.
Do I have to move my money to use one?
No. Tengu connects to the brokerage accounts you already have; your funds and securities never leave your broker. If a product requires depositing funds with the vendor, that is a different and riskier arrangement.
Can I disconnect it from my brokerage account?
Yes, at any time. The connection is a permission you grant, not a transfer. Revoke it in Tengu or from your broker's side and the AI loses access immediately; your account, holdings, and cash stay exactly where they were.
