Building a Polymarket 5-minute BTC desk with Claude Code and Jev probabilities
Combining jevymarket's decision pipeline with Polymarket's SDK lets Jev output probabilities from BTC evidence while code enforces position limits, kill switches and trade logging.
5-MINUTE BTC MARKETS JUST HAD THEIR CTRL+V MOMENT The building blocks of a Polymarket trading desk are already on GitHub. Now put Claude Code between them. markusbug/jevymarket → Jev's decision pipeline. Polymarket/py-sdk → official data and execution. One prompt tells Claude how to turn those pieces into a BTC trading lab: > Discover the next 5-minute Up/Down market. > Stream fresh BTC data and read the actual settlement rule. > Ask Jev for a probability using the evidence you provide. > Compare it with executable odds after fees and slippage. > Let code enforce position limits, exposure caps and the kill switch. > Record every forecast, skipped trade, fill and resolved outcome. 288 windows a day. Every decision becomes something you can test. Change one variable. Replay the results. Keep what survives validation. Claude builds. Jev evaluates. Code controls the money. The barrier to building this machinery is collapsing. The next competitor in your market could be someone who opened GitHub yesterday. Save the prompt. Paste it into Claude Code. Build your own loop.
