Polymarket has initiated a review of its Builders Program following concerns over copy trading applications and insider-like behavior. The program, launched in November, allows developers to create trading apps on Polymarket's infrastructure, attracting around 200 developers with potential funding of up to $2.5 million. However, several developers have focused on copy-trading apps, which replicate trades from accounts with high win rates, raising ethical concerns. The trading volume from the Builders Program surged from $100 million in November to over $600 million in March, comprising 16% of Polymarket's total volume. Despite the growth, security issues have arisen, with apps like PolyGun and Polycule suffering hacks resulting in significant financial losses. Additionally, insider trading concerns have been highlighted by suspicious betting activities, prompting Polymarket to partner with Palantir for enhanced compliance monitoring. The platform's trading volume reached $23 billion in March, amid scrutiny from U.S. legislators over its operations.
