A sophomore computer science student used Claude to write a quant trading robot, which has been running automatically on Polymarket. So far, it has netted more than $140k.

The robot went live on March 24, ran for 105 days, averaged $1,366 in daily earnings, and completed more than 29 trades per hour—pretty high frequency. It made 73,015 cumulative prediction trades, and its long-term win rate has remained stable at 59%.

The trader account is here:

The concept of the gameplay isn’t actually complicated. It’s essentially a reusable playbook:
· Watch short-term crypto market moves, and enter in the exact moment when the order book quotes can’t keep up;
· When the market has adjusted the price and the spread is about to disappear, close the position and leave;
· Tens of thousands of trades, all following this same process—mechanical execution with no emotions;
· Don’t rely on hitting some one big bet to make huge gains; instead, roll over each small spread repeatedly to slowly stack profits.

The top three profitable trades in the account:
1. Invested $2,207, got back $3,562, net profit $1,355, return 61.4%
2. Invested $1,166, got back $2,288, net profit $1,122, return 96.2%
3. Invested $1,354, got back $2,453, net profit $1,098, return 81.1%

This system can keep making money. The key isn’t catching some big breakout—it’s grabbing those fleeting pricing discrepancies, trade after trade, grinding them down, and steadily shaping the profit curve into an upward-sloping line that just keeps going.
