"Polymarket is in the process of hiring an in-house team to engage in trading activities against its customers, and it's important to understand the potential risks associated with this decision. By allowing their own employees to trade against users, Polymarket could create a conflict of interest that may undermine customer trust, lead to ethical concerns, and ultimately affect the integrity of the platform. This raises questions about the fairness of the trading environment and whether customers can expect a level playing field when participating in the markets."
