A user profile on Polymarket has reportedly leveraged a DIY market maker bot to exploit early-market inefficiencies, generating approximately $181,000 in profit. The bot has executed nearly 1,000,000 trades across 22,790 markets, effectively acting as an unofficial automated market maker (AMM) in the absence of an official one on the platform. The strategy involves entering markets immediately upon opening to secure optimal entry points before human traders can react. By maintaining minimal downside risk and capitalizing on market repricing, the bot systematically profits from early probability buys. This highlights the importance of speed and discipline over complex analysis in Polymarket trading, where bots often set the initial efficient prices.
