I reverse engineered 3 Polymarket bots that made $4.3M · Lewis Jackson

Bot X-Ray, from the video.

Paste one prompt into Claude Code or Codex and it installs on your own computer. Give it any Polymarket wallet and it shows what the bot does, whether it was skill or luck, and whether it still works.

No charge for the prompt or the app. Mac, Windows or Linux. It reads Polymarket’s public data, so you don’t need an account, and it never trades on Polymarket.

Bot X-Ray’s Wallet screen for 0x8dxd: its lifetime P&L as a line that stops rising, with blue lines on the days Polymarket changed its rules
A real screenshot of Bot X-Ray, 16 Oct 2026: 0x8dxd made $2.17M, then stopped. The blue lines are the days Polymarket changed its rules.

Where the numbers come from

Every trade on Polymarket is public. Bot X-Ray reads it from Polymarket’s own public data, with no account and no API key.

What it doesn’t do: trade on Polymarket. In the UK, the US and much of Europe you can’t open trades there anyway. It shows what bots did, and it promises nothing about what a strategy will make.

What you get

  • The Wallet screen in Bot X-Ray: a wallet’s lifetime P&L as a line, with blue lines on the days Polymarket changed its rules
    Wallet

    Any wallet’s lifetime P&L, with the days Polymarket changed the rules marked: fees on 5 January, the half-second delay removed around 18 February, the new fee curve on 30 March. Then month by month: P&L, volume, fees and profit on every dollar.

  • The What it does screen in Bot X-Ray: a one-sentence summary of the bot, the Binance test and which markets it trades
    What it does

    The trick in one sentence. Which markets it trades, whether it buys both sides and what a pair costs it, whether it ever sells, and the Binance test: after Bitcoin moves, does the bot buy that side?

  • The Skill or luck screen in Bot X-Ray: green days, the longest winning run and the odds of getting it by flipping a coin
    Skill or luck

    Green days, the longest winning run and the odds of getting it by flipping a coin, plus the checks quant desks use to tell an edge from a lucky streak.

  • The Still working screen in Bot X-Ray: the last 30, 60 and 90 days against the wallet’s lifetime
    Still working?

    The last 30, 60 and 90 days against its lifetime, profit on every dollar month by month, and how much of the profit fees took.

  • The Who’s winning now screen in Bot X-Ray, filtered to the wallets whose results a coin flip can’t explain
    Who’s winning now

    The top crypto earners on Polymarket this week, this month or all time, each tagged by what its latest trades show and checked for skill or luck. Filter to the ones a coin flip can’t explain.

  • The Trade it with a broker screen in Bot X-Ray: 0x8dxd’s speed trade converted for a crypto exchange, with the rules, what’s lost and the prompt Claude builds it from
    Trade it with a broker

    Every bot here traded Polymarket’s yes-or-no markets. This tab converts each one to markets a broker offers: options, Kalshi, a crypto exchange, a stock broker or futures. You get the rules, with numbers from the bot’s own trades, and what’s lost on the way. Two versions are built in and run on paper. Claude writes the rest when you ask, and the tab says which is which.

  • The Live gap screen in Bot X-Ray: Bitcoin on Binance against Polymarket’s 15-minute market, once a second
    Live gap

    Once a second: Bitcoin on Binance against Polymarket’s 15-minute market. Every “bargain” a simple model spots becomes a paper trade, so you can watch whether it was real.

  • The Strategy screen in Bot X-Ray in paper mode: open positions and the contracts the model prices too low
    The strategy, on paper

    The one that’s still running: price a “will it be above this price on Friday” market like an option, buy the side priced too low and hold it to the end. It runs on paper on markets you can trade where you live: Kalshi’s Bitcoin and Ether markets in the US, or Bitcoin and Ether ETF option spreads with a broker that offers US-listed options. Connect your own broker when you’re ready. Nothing trades until you arm it yourself.

  • Ask Claude

    One command connects Claude Code. Then ask it: “Reverse engineer the Polymarket wallet 0x8dxd,” or “Convert it for my broker.”

Questions

Does it cost anything?

No charge for the prompt or the app. You need Claude Code or Codex to run the prompt, and those come with their own plans.

Do I need a Polymarket account?

No. Every trade on Polymarket is public, so Bot X-Ray reads it without one. In the UK, the US and much of Europe you can’t open trades on Polymarket, and Bot X-Ray never trades there.

I can’t trade on Polymarket. What do I do with this?

Open the “Trade it with a broker” tab on any bot. It converts the bot’s trick to markets a broker offers and says which versions are built in and which Claude writes for you. Some tricks don’t convert at all, and it says why: a spot position can’t copy a yes-or-no payoff, for example.

Is this the $1M bot?

No. It shows what that bot and the others did, from their own trades. Two of the three famous bots stopped after Polymarket changed its rules. Anyone selling “the bot” in comments or messages is a scam.

Where does the data come from?

Polymarket’s public data for trades, P&L and results, Binance for Bitcoin second by second, and Kalshi and CBOE for the strategy’s prices. The table above says how fresh each one is.

Can the strategy trade real money?

It starts on paper. When you’re ready, ask Claude to connect your own broker, and it stays on paper until you arm it yourself in your own terminal. Kalshi’s markets are for US residents and the other countries Kalshi accepts. The ETF option spreads need an options account with a broker that offers US-listed options where you live.

Will it make money?

It shows what other wallets made, which is public record. That says nothing about what you’ll make, and nothing here promises a profit. Most of the “bargains” a simple model spots are the model being wrong.

Do I need to know how to code?

No. You paste one prompt and the agent does the setup.

How long does it take to set up?

In testing, Claude Code finished in 27 seconds, starting from an empty folder.

Does it work on Windows?

Yes. Windows, Mac and Linux, with Node.js 18 or newer.

How do I update it?

Paste the prompt again in the same folder. Your settings and paper trades stay.
