There is a programmer intern in Guangzhou who built a robot using Claude and earned $223,000 on Polymarket.

His bot executes 113 trades per hour, focusing on the microstructure of short-term crypto up/down markets; the median trade size is only $2.12 per trade.
The strategy is simple:
When the outcome is basically decided, but there is still room for profit on Polymarket, buy in the $0.98 to $0.999 range. Then use small positions—$0.01 to $0.05—to buy some tail outcomes, to prevent the underlying asset from suddenly moving in the last few seconds. Sometimes, when an arbitrage opportunity is spotted, he goes ahead and takes it as well.

Just by relying on this strategy and executing cleanly, he has been consistently profitable, and his capital has been gradually growing.
