Setup for Claude Code

The 98¢ Trade

A prediction-market bot that sets itself up. Download the folder, open it in Claude Code and type hi.

Backtested on 8,318 Polymarket trades. 99% paid out.

What you get for €5

  1. A bot that runs every day

    Claude installs it and schedules a daily scan in about ten minutes. You paste one API key and never write a line of code.

  2. A small, tested edge

    It buys bets priced 97 to 99.5¢ that settle within a week, after Jev, TypeSafe's AI, has read each market's rules. It starts with practice money and only suggests real trades once it passes a checklist.

  3. An idea you'll understand

    Crowds slightly underprice outcomes that are nearly certain. The guides explain why that happens, how a market decides who gets paid, and how to test a strategy before you trust it.

  4. Code you can build on

    You get all of it: the Python bot, the research scripts and all 8,318 backtested trades. Add a market, try your own filter, or point Jev at something else entirely.

From losing 5 trades in 7 to losing 1 in 104

The first bot guessed which way crypto would move in the next five minutes, and most guesses lost. The 98¢ Trade stopped guessing. It only buys what the market already prices at 97 to 99.5¢, and Jev reads each market’s rules first.

Questions

Do I need to know how to code?
No. Claude installs everything and walks you through each step. The only thing you do yourself is paste one API key into a file.
Does it trade with my money?
Not at first. It trades practice money on real prices. Once it passes its go-live checklist, usually after four to eight weeks, it suggests real trades and you place them yourself.
How much can I make?
Nobody can promise a number. In the backtest the average trade made +0.58%, and about 1 in 100 lost its whole stake. Expect small, steady gains.
What does it cost to run?
Jev costs about 1 to 2 cents a day, paid to TypeSafe. The €5 is a one-time payment with no subscription. You also need Claude Code, which comes with a paid Claude plan.
Can I use it where I live?
Practice trading works anywhere. Real trading depends on your country: international Polymarket doesn't accept orders from the US, the UK, Italy and a few others, and Kalshi covers the US and many more. The folder has a guide to both.
How do I get it?
The download opens right after you pay, and the folder is emailed to you as well. If you buy on your phone, open the email on your computer.

Not financial advice. About 1 in 100 of these trades loses its stake, and past results don’t guarantee future ones. Prediction markets are restricted in some countries.
