Is QuantGPT legit?
Updated October 22, 2026
Yes. QuantGPT (quantgpt.co) is research software made by QuantGPT LLC, a Florida company. It lets you, or Claude and ChatGPT connected over MCP, run backtests on decades of US market history. It does not hold your money, does not take deposits, does not promise returns and cannot place trades for you on its own: no tool your AI can call through QuantGPT places an order, and QuantGPT never decides, sizes or manages a trade.
On QuantGPT Pro, your own code can run on QuantGPT Cloud and send orders to your own Alpaca account, under your keys. Those orders are your code's, never QuantGPT's choice.

What QuantGPT is
- A research platform. The terminal at terminal.quantgpt.co runs backtests, screens and studies on decades of US market data, on QuantGPT's own servers.
- An MCP server at
https://terminal.quantgpt.co/mcp. Claude, ChatGPT, Gemini, Cursor and any MCP client connect to it and run the same tools from a chat. - A strategy library of 175 documented strategies from the research literature and well-known investors, 55 of them runnable in one click. It is free to read.
- Two plans. QuantGPT is $49 a month and QuantGPT Pro $149 a month ($490 and $1,490 a year). Each starts with a 3-day free trial, card up front: cancel any time before the 3 days end and you pay nothing. Every new account starts on one of the two plans, with that trial.
What QuantGPT is not
| QuantGPT is not | What that means |
|---|---|
| An investment adviser | It publishes research and runs tests that return the same result for anyone who asks the same thing. It never tells you what to buy, sell or hold. |
| A broker or a fund | It holds no money, takes no deposits and pools nothing. Your money stays at your own broker. Plans are a flat subscription, never a fee on trades or results. |
| An auto-trading bot that trades for you | No tool your AI can call through QuantGPT places, changes or cancels an order. On QuantGPT Pro your own code can run on QuantGPT Cloud at your own Alpaca account, under your keys; before it trades a live account, you attest that you wrote or reviewed every line. QuantGPT never decides, sizes, times or manages a trade. |
| A promise of returns | A backtest shows what a rule did on past data. It is not a prediction, and nothing on QuantGPT promises a profit. |
QuantGPT is not Quantum AI or QuantumGPT
Regulators in several countries have published warnings about a firm calling itself Quantum AI, among them the UK Financial Conduct Authority (first published May 14, 2025) and the Danish Financial Supervisory Authority (October 30, 2025). QuantGPT LLC has no connection to that firm or to any other business with a similar name.
- QuantGPT never asks for a deposit and never holds or invests anyone's money.
- QuantGPT never calls or messages anyone to solicit an investment.
- QuantGPT never promises profits.
- The only charge to a member is the plan subscription, paid by card through Stripe at checkout from terminal.quantgpt.co/join.
Anyone who asks you for money "for QuantGPT" any other way is not us. Report it to desk@quantgpt.co.
Not the open-source QuantGPT projects
Several open-source projects on GitHub are also named QuantGPT. They are separate projects with no connection to QuantGPT LLC or quantgpt.co. QuantGPT's own GitHub organization is github.com/quantgptco, and its public repository is github.com/quantgptco/quantgpt-mcp, the listing for the hosted MCP server at https://terminal.quantgpt.co/mcp.
How you can check us yourself
- The data. The verify page needs no key and no signup. It publishes the warehouse's coverage and method, and returns any daily bar, by ticker and date, to check against a source you trust.
- The results. Every backtest in the terminal shows its worst fall from a peak, its losing calendar years and the same statistics split at a cut year (2015 unless you pick another), beside the benchmark, gross of trading costs.
- The trial. The 3-day trial runs on the plan's full daily limits: 200 backtests a day, and 500 AI calls a day on QuantGPT or 1,500 on QuantGPT Pro.
- The tools. Once your AI is connected, ask it to call
available_tools(ChatGPT shows them in its tool list instead): it lists every tool by name and description, and none of them places, changes or cancels an order.describe_capabilitiesreturns the map of the data, the factors, the benchmarks and the method.

QuantGPT reviews

It is listed in The Official MCP Registry (co.quantgpt/mcp), Smithery (smithery.ai/servers/quantgpt/quantgpt) and GitHub (github.com/quantgptco/quantgpt-mcp). Those are directory listings, not reviews, and QuantGPT publishes no testimonials. Independent reviews are welcome: write to desk@quantgpt.co.
Is QuantGPT a good platform for AI trading?
QuantGPT is built for the research side: Claude, ChatGPT or any MCP client connects to decades of US market data, and the backtests run on QuantGPT's servers, so your AI gets back finished results with the worst fall, the losing years and a cut-year split. It does not trade for you. Orders go through your own broker: you place them, or on QuantGPT Pro your own code on QuantGPT Cloud sends them to your own Alpaca account, under your keys. Whether it fits depends on what you want to test.
Is QuantGPT Pro worth it?
That depends on whether you use what it adds. QuantGPT Pro is $149 a month ($1,490 a year) against $49 for QuantGPT, and adds 1,500 AI calls a day and 5 keys (against 500 and 3), the QuantGPT Pro rooms on the forum, the Excel valuation model, and QuantGPT Cloud, which runs your own code at your own Alpaca account. The leaderboard is on both plans. Each plan starts with a 3-day free trial on its full daily limits.
