How I Made $1,500 Risk-Free on Polymarket by Exploiting Bot Incentives

By spotting illiquid Harmonix markets on Polymarket, I exploited rebalancing bots chasing USDC rewards. With just $100, I repeatedly trapped their auto-orders between bid-ask spreads—earning $1,500 in two hours, completely risk-free.

I just made 1500$ on @Polymarket in 2 hours, fully risk free, with just 100$ capital.

For context, Polymarket has an incentive program where you can get USDC rewards for placing limit order around mid price of a market

Some people have bot that automatically rebalance their limit order when the price move, so they continue to accrue USDC rewards

But what happen when the market is illiquid ? They get rekt😬

Today, I just discovered these illiquid Harmonix markets, we will only focus on the "25m fdv" market here

The best bid is at 33c, and when I put a 5 shares sell order at 34c, the bot automatically add 100 shares sell order at the same price to stay in range

So I buy his 100 shares at 34c Then I will put a 5 shares buy order at 58c (best ask is 59c)
The bot will put 100 shares buy order at 58c (to stay within the range for USDC incentives), and I will dump on him

Just repeat until the bot run out of money
